What does the discovery of glossopteris fossils in five continents suggest

The Glossopteris fossil is found in Australia, Antarctica, India, South Africa, and South America—all the southern continents. Now, the Glossopteris seed is known to be large and bulky and therefore could not have drifted or flown across the oceans to a separate continent Glossopteris fossils were critical in recognizing former connections between the various fragments of Gondwana: South America, Africa, India, Australia, New Zealand, and Antarctica

Evidence Alfred Wegener: Building a Case for Continental

In the above map, orange indicates the fossil remains of Cynognathus, a Triassic land reptile. Dark blue indicates fossil remains of the freshwater reptile Mesosaurus. Green indicates fossils of the fern Glossopteris, found in all of the southern continents. Brown indicates fossil evidence of the Triassic land reptile Lystrosaurus Glossopteris, genus of fossilized woody plants known from rocks that have been dated to the Permian and Triassic periods (roughly 300 to 200 million years ago), deposited on the southern supercontinent of Gondwana. Glossopteris occurred in a variety of growth forms

The locations of glossopteris fossils, mesosaurs fossils found in South America and Africa, the make up of the Appalachia mountains is the same as ancient mountains in Greenland and Western Europe, cynognathus fossils found in South America and Africa, Brachiosaurus fossils found in Colorado and Tanzania, coal deposits found in Antarctica, all of these along with the shape of the continents suggest that they were all once part of the same land mass, or single continent The discovery of Glossopteris fossils proves that the continents were once connected. Q14. Finding Glossopteris fossils in Antarctica shows us that the climate there was? Finding Glossopteris fossils in Antarctica would mean that its climate was tropical to subtropical at one time

Can you suggest a possible mechanism driving the movement of entire continents? Glossopteris is a genus of fern plants known to have thrived in humid tropical and temperate climates. What does this information tell you about the climate of ancient Antarctica? Lystrosaurus fossils have been discovered in present-day China and Southeast Asia. These fossils do strongly indicate that the landmasses were once joined together, as these come from creatures that could not have swam or drifted across the oceans. But it's not just these fossils. Other species with similar geographic spread and limited water-borne mobility have also been found One plant, the Glossopteris was discovered five different continents. Its heavy seeds couldn't have been blown by the wind or floated across the wide ocean. So Wegener concluded that all those continents must have been connected with Glossopteris was alive Fossils of Lystrosaurus are only found in Antarctica, India and South Africa. Glossopteris was a woody, seed-bearing shrub or tree, named after the Greek descripton of 'tongue' - a description of the shape of the leaves. Some reached 30m tall. It evolved during the Early Permian (299 million years ago) and went on to become the dominant. The locations where Glossopteris fossils not have evolved on separate continents, and the presence of the fossils and coal beds was best explained if all of the Laws & Discovery 5:2

Fossil evidence of Glossopteris has been discovered in South America, Africa, India, Antarctica and Australia. Importantly, the seeds of the plant were massive and could not have floated or been. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator. This would indicate that the glaciers either formed in the middle of the ocean and/or covered most of the Earth

  1. The Glossopteridales (Glossopteris fossils ) occur on the most landmasses. Their distribution across several detached landmasses led scientists to believe that these were once merged into a single supercontinent, Pangea. Which fossil occurs on most of the landmasses What does this suggest about when these continents broke up
  2. Yet Glossopteris fossils are found in South America, Africa, Australia, India, and Antarctica! The mountain belts along the margins of North America, Africa, and Europe line up as well and have similar rock types, an indication that the continents at one time were joined as Pangaea

Glossopteris fossil plant genus Britannic

The scientists found fossils of Glossopteris, a tree-like plant. Glossopteris fossils had already been found in Australia and Africa. Glossopteris Fossil of part of Glossopteris (not to scale) The discovery of Glossopteris fossils in Antarctica provided evidence for Wegener's theory. Suggest how Glossopteris and coal do not occur above the Permo-Triassic boundary, however. In their place are red beds that formed in a warm and wet interval at the beginning of the Triassic. Following the Permian-Triassic extinction, the Dicroidium flora in Antarctica and other Gondwana continents replaced the typical Glossopteris flora

Ancient fossils of the same species of extinct plants and animals are found in rocks of the same age but are on continents that are now widely separated (figure 3). Wegener proposed that the organisms had lived side by side, but that the lands had moved apart after they were dead and fossilized answer choices. having the longest necks to reach food at higher levels than the others. having the brightest fur to blend into the environment, avoiding predators. having the most spots to be able to attract more mates for reproduction. having the sharpest teeth to break down plant matter, absorbing more nutrients The fossils of Mesosaurus, a freshwater reptile, or rather a small crocodile, found both in Brazil and South Africa, are one example. Another is the discovery of fossils of the land reptile Lystrosaurus found in rocks of the same age in places in Africa, India and Antarctica. There is also evidence that the same animals are found on two continents The Independent reported Erik Gulbranson and John Isbell of the University of Wisconsin-Milwaukee are behind this impressive discovery. The two scientists trekked across the Transantarctic Mountains during the continent's summer, between November and January. They found 280-million-year-old tree fossils among the rocks where a leafy forest. By 1828, fossils of Glossopteris had been discovered to have inhabited both the Northern and Southern Hemisphere continents in the remote geological past. To explain the observed distribution patterns of flora and fauna, scientists hypothesized that land bridges had linked the widely separated Southern Hemisphere continents in the geological past


Q13. What do the Glossopteris fossils tell us about the ..

  1. 16. According to paragraph 2, maps played a role in the development of the plate tectonics theory by. (A) showing the paths of the moving continents. (B) helping scientists record the locations of different fossils. (C) stimulating curiosity about the parallels between coastlines. (D) outlining the locations of underwater land bridges
  2. Early Evidence: Fossils and Puzzle Pieces. Plate tectonics is a relatively new theory. It was first proposed in 1912 by Alfred Lother Wegener as a theory called continental drift. Wegener's theory was initially based upon the remarkable shape of our continents, particularly South America and Africa. He spent his life traveling around the.
  3. The figure below shows how some of the continents were joined as part of Pangaea 250 million years ago. The lighter area on the map shows where Glossopteris fossils have been found. Notice that the plant once grew in parts of five continents-South America, Africa, India, Antarctica, and Australia. Because these plants grew in a swamp
  4. Continental Drift. Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils
  5. In the fall of 1911, though, he came across a scientific paper that described the locations of identical plant and animal fossils on very different continents. These fossils included mesosaurus.
  6. area on the map shows where Glossopteris fossils have been found. Notice that the plant once grew in parts of five continents—South America, Africa, India, Antarctica, and Australia. Because these plants grew in a swampy environment, this region, including Antarctica, was different from how it is today. Most of Antarctica is covered in ice.
  7. Alfred Wegener's Theory Of Pangaea And Continental Drift. Of the fossils used were Glossopteris and Mesosaurus. One may wonder why these two. The Glossopteris (seed fern) produced seeds that were too large and heavy to be carried upon the air over oceans (Lutgens, Tarbuck, & Tasa, 2014). The Glossopteris has been found on several continents.

Lystrosaurus Lystrosaurus (meaning shovel lizard in Greek) is an extinct genus of dicynodont therapsid that lived during the Late Permian and Early Triassic periods, around 250 million years ago in what is now Antarctica, India and South Africa. At present 4 to 6 species are recognized, although from the 1930s to 1970s the number of species was thought to be much higher. Lystrosaurus had. Marine Plain in the Vestfold Hills has a great diversity of fossils from 4.5 to 4.1 million years ago. The best known are the fossil dolphins and whales. About 5 or 6 species are known. The dolphins are very different from modern dolphins. They consist of two species, one about 4.5 m long and the other about 8 to 9 m long Glacial Deposits. Today, glacial deposits formed during the Permo-Carboniferous glaciation (about 300 million years ago) are found in Antarctica, Africa, South America, India and Australia. If the continents haven't moved, then this would suggest an ice sheet extended from the south pole to the equator at this time - which is unlikely as the.

  1. d goes when its cartesian other half is stuck between four walls. From the Dunning-Kruger effect, much in.
  2. For example, rocks in Alaska contain fossil palm tree leaves though there have not been palm trees at that latitude for a very long time. In addition, when you look critically at the map of the world, some of the continents can be fit together like a puzzle. For instance, South America and Africa can be fitted together
  3. In the fossil record, identical plants, such as the extinct seed fern Glossopteris, are found on now widely disparate continents. And mountain chains that now lie on different continents, such as.
  4. From the mid-19th century, fossils were used as evidence for continental drift - but mainstream scientists didn't buy it until the 1950s. Frank Jacobs. 10 April, 2020. Fossil finds pointed the.

Glossopteris fossils, found in Antarctica (and all southern continents), inspired Alfred Wegner to first propose the concept of Pangaea and continental drift. Cultural artifacts found in Alaska suggest an ancient migration across the Bering land bridge. Recently discovered dinosaur fossils in both polar regions raise interesting questions about. The name Pangea comes from an ancient Greek word meaning all lands. This term was first used in the early 20th century when Alfred Wegener noticed that the Earth's continents seemed to fit together like a jigsaw puzzle. He later developed the theory of continental drift to explain the shapes and positions of continents and coined the title Pangea at a symposium in 1927 on the topic

Alfred Wegener, German meteorologist and geophysicist who formulated the first complete statement of the continental drift hypothesis. His theory was rejected by most geologists during his lifetime but was resurrected and made a central feature of modern geology as part of the theory of plate tectonics in the 1960s Another fossil was of a small fern, Glossopteris, which were found widely across all southern continents, also suggesting that the landmasses were once joined and such creatures and plants lived in the whole combined area continental drift was Glossopteris, a seed fern that resembled low shrubs. Fossils of this plant had been found on many continents, which today have very different climates. Because he had a strong background in meteorology,Wegener was able to reason that the area separating these fossil finds was too large to have had a single cli-mate

Do the glossopteris fossils tell us that all landmasses

Therefore, these creatures must have lived on a giant continent that later broke apart, and the pieces drifted away from each other. Fossil records are strong evidence that the continents do drift. Answer 5: Fossils are formed when living organisms (plants or animals) die and become buried in dirt, sand or mud 2. The land mass broke apart, and the continents _____to their present positions. 3. Evidence for continental drift a. Puzzle-like fit of the continents b. Similar fossils have been found on different continents. c. Remains of warm-weather plants in Arctic areas and glacial deposits in tropical areas suggest that continents have moved. d

The Origin of Continents and Oceans. Topics: Plate tectonics, Continent, Geology Pages: 1 (279 words) Published: March 7, 2013. In 1915 the first edition of The Origin of Continents and Oceans, a book outlining the Continental Drift theory of Alfred Lothar Wegener, a German meteorologist, was published; expanded editions were published in 1920. The discovery of a presumed coniferophyte with erect terminal ovules from the Permian of Antarctica adds support to the hypothesis that there were at least two major groups of conifer-like plants present during the late Paleozoic. Smaller shoots that contain fewer leaves suggest stem diameters of about 2.5 and Glossopteris fossils from. About Mesosaurus . Mesosaurus was the odd duck (if you'll excuse the mixed species metaphor) among its fellow prehistoric reptiles of the early Permian period. For one thing, this slender creature was an anapsid reptile, meaning it did not have any characteristic openings on the sides of its skull, rather than a more common synapsid (a category that embraced the pelycosaurs, archosaurs and.

Glencoe: Focus on Earth Science: Chapter 4: Lesson 1

Fossil Evidence. As early as the 1900's, scientists had found many examples of fossils of the same species of plant or animal, but were found on completely different continents. Some of the same fossils were even separated by entire oceans. Turn on the Fossil Distribution layer. List the continents that Glossopteris Fossils have been found on Almost 200 years after the discovery and formal description of Glossopteris, a widespread fossil gymnosperm of India and the southern continents, several key questions remain unanswered about this plant group

5. Note that the map changes, moving the continents to their positions during the time period that you clicked. In 1-3 sentences, describe changes in the distribution of your fossil. Also, save a copy of your map and paste it here. Part 2: Mesosaurus, and Glossopteris 1. Enter Mesosaurus in the search field and click enter. 2 Antarctica is a continent on the bottom of the world. During the age of dinosaurs and reptiles, Antarctica was located further north close to Australia and was home to lush conifer forest where many dinosaurs thrived in these conditions. After the dinosaurs in the Cenozoic, while the continents.. Genus Tiktaalik is a transitional fossil meaning that it has an evolutionary transition being from fish to four legged animals 3. 2004 4. Devonian 5. In a Poland quarry tracks were found that suggested that the many tetrapods existed long before the genus tiktaalik

The Geological Societ

One of the fossils he studied, the Glossopteris, a fern that could grow to 30m in height that lived during the Permian period, had been found on the continents of South America, Australia, Africa, and Antarctica, as well as India and Madagascar. This phenomenon had previously been explained by Suess's idea of sunken continents (land bridges. The distribution of Glossopteris across the now dispersed southern continents (Fig. 5) was cited as early evidence in support of the theory of continental drift proposed by Alfred Wegener (1880-1930). Figure 5 - Distribution of Glossopteris fossils across the southern continents. Animals of the coal swamps the fossils he studied. Glossopteris fossil Coal in Antarctica Glacial Deposits Glossopteris distribution map Coal in Antarctica Distance between the Atlantic The distance from South America to Africa is roughly 1600 miles. If these continents move apart at a rate of .5 inches per year, how many years would it hav The discovery of rich assemblages of Glossopteris Flora sharing the same taxa at different austral continents today distant from each other, is one of the most important geological evidence that these continental lands were once connected to each other (Plumstead, 1973) Dinosaur and mosasaur (massive swimming reptiles) fossils occur on every continent including Antarctica. These discoveries demonstrate that a much warmer global climate existed in the pre-Flood world. 2 Warm-weather plants like Glossopteris have been found in Permian rocks on Antarctica for decades and are often used to make plate tectonic.

Glossopteris was formally defined by Brongniart (), and the genus has been emended subsequently by several workers.This fossil-genus of tongue-shaped leaves with reticulate venation characterizes continental strata throughout the middle- to high-latitude regions of the Gondwanan Permian (McLoughlin, 2001, 2011).Indeed, the distribution of the genus was central to early arguments that the. Beautifully preserved coalified specimens of dichotomously branched elongated, ribbon like thalloid metzgeriinean bryophyte, Pantiathallites gondwanensis gen. et sp. nov. is described from the late early Permian of Gondwana, India. The thalloid bryophytes once or twice forked with wider midrib occur abundantly in a rich assemblage of Glossopteris and Gangamopteris species and diverse sterile.

Cleary asserts that other discoveries suggest that the pre-Flood climate was much warmer than many assumed: Dinosaur and mosasaur (massive swimming reptiles) fossils occur on every continent. All the localities containing Lower Gondwana fossils, but bearing the lithological characteristics of the Upper Gondwanas such as Panchet, Pachmari, Parsona, Maleri etc. are retained in the Middle Gondwana (Table 1.3). The Middle Gondwana is characterised by Dicroidium flora, present in between the Glossopteris and Ptilophyllum floras extends beyond the continent until there is a large change in slope. By about 300 million years ago, a unique community of plants had evolved known as the European flora. Fossils of these plants are found in Europe and other areas. Color the areas with these fossils yellow. Fossils of the fern Glossopteris have been found in these locations. The reason why Glossopteris, a tropical plant was discovered in Antartica is, because the continents were connected together as one continent, also known as Pangea. Antartica was probably a hot. • fossil remains of mesosaurus, a prehistoric reptile, are found in both southern Africa and South America; • the plant Glossopteris is a fern that has been found in Africa, Antarctica, Australia and South America. It is used as evidence that these continents must have been joined together around 250 million years ago

Lesson Summary. Alfred Wegener gathered evidence that the continents had moved around on Earth's surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climate zones. Although the evidence was extremely strong, scientists did. Evidence of Plate Tectonics. Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life rode on diverging plates, became isolated, and evolved into new species

Distribution of Fossils across the Gondwanaland Presence of glossopteris vegetation in Carboniferous rocks of India, Australia, South Africa, Falkland Islands (Overseas territory of UK), Antarctica, etc. (all split from the same landmass called Gondwana) can be explained from the fact that parts were linked in the past Fossils and geologic evidence show that most of the continents used to have startlingly different climates than they do today. Wegener thought continental drift was the key to these climatic puzzles, so he and Vladimir Koppen plotted ancient deserts, jungles, and ice sheets on paleogeographic maps based on Wegener's theory Suess based his deductions on the fossil plant Glossopteris, which is found throughout India, South America, southern Africa, Australia, and Antarctica. Fossils of Mesosaurus (one of the first marine reptiles, even older than the dinosaurs) were found in both South America and South Africa. These finds, plus the study of sedimentation and the.

Glossopteris: Fossils, Overview - Video & Lesson

Earth is 5 billion years old but the history of life on earth began almost 3,5 mya. CONTINENTAL DRIFT: All the continents were joined as one big land mass called PANGAEA and began to break into smaller continents making wider oceans and place for more marine life. South African examples of continental drift include the discovery of the fossils of Alfred Wegener and Plate Tectonics. Close examination of a globe often results in the observation that most of the continents seem to fit together like a puzzle: the west African coastline seems to snuggle nicely into the east coast of South America and the Caribbean sea; and a similar fit appears across the Pacific that live only on one continent. For example, lions live in Africa but not in South America. Because oceans separate the continents, animals cannot travel from one continent to another by natural means. However, fossils of similar organisms have been discovered on several continents that are now separated by oceans. Glossopteris (glahs AHP tur us

Description of Fossil Location:Glossopteris Latitude and Longitude (approximate) South America: fossils have been found in a small area that extends from the middle of the continent to its eastern coast. a band from 32 o S, 65 o W to 34 o S, 53 o W that extends back to 37 o S, 58 o W Africa: fossils have been found in a band that extends from. The scientists used many kinds of evidence to advance their theories. They found similar fossil remains of plants and animals on different present-day continents. The scientists hypothesized that the continents were once connected Wegener reasoned that the area separating these fossils was too large to have had a single climate. Wegener argued that because . Glossopteris. grew in . temperate. climates, the places where the fossils had been found had been closer to the equator. This led him to conclude that the rocks containing these fossil ferns had once been joined

Although sandstone fossils for this area are rare the ones that are discovered offer an insight into what it may have been like during this period. A few years ago a fossil collector found bone fragments amongst rocks that had been bulldozed for road works near Picton, after six years a near-complete one meter long fossil of a fresh water shark. 2. FOSSILS Wegener also found fossils of the same plants and animals on different continents now separated by vast oceans. They could only be found this way if the continents had once been joined together Plate Tectonics, Fossils, & Extinction. In 1915 German geologist Alfred Wegener proposed the theory of continental drift by arguing that the earth's continents move over time on earth's surface.. Today plate tectonic theory based on Wegener's work is accepted as the unifying theory of geology, the study of earth's physical structures.. P late tectonics is the theory that the outer rigid. Wegener's accumulated evidence could be most logically explained by continental drift. His ideas attracted much attention in the 1920s —and generated much controversy. Some Southern Hemisphere geologists, particularly in South Africa, responded with enthusiasm. The general response to Wegener's hypothesis, however, was disbelief ferns are compared with the fossil genus, and in one example of Glossopteris certain ill-defined spots are spoken of as traces of rounded groups of sori. Since Brongniart's diagnosis was published thousands of Glossopteris leaves have been discovered in India, Australia and Africa, but we are still in doubt as to the precise affinities of the.
