What do Glossopteris fossils tell us about the early position of continents it proves that?
Glossopteris fossils tell us that the continents especially Southern Africa, Australia, India and Antarctica which are now separated by wide oceans were once connected because the large seeds of this plant could not possibly travel a long journey by the wind or survive a rough ride through ocean waves.
What do Glossopteris fossils tell us?
The glossopteris fossils mirror the proof of separation of continents like southern Africa, Australia, India, and Antarctica which became in large part separated through the big and extensive ocean which became in advance linked with every different due to the fact the big seeds of this plant couldn't probably tour a ...
Why are Glossopteris fossils important what can they tell us about Earth?

What does the Glossopteris plant tell us about the climate of Antarctica?
Throughout the area the scientists found the tongue-shaped imprints of fallen Glossopteris leaves. Deciduous trees such as Glossopteris are an indicator of a warm climate, as is the absence of frost rings.
What best describes Glossopteris?
Glossopteris, which gives its name to the flora, is characterized by a leaf with a fairly well defined midrib and a reticulate (net-like) venation. G. indica is the last species referred to the genus and to the family Glossopteridales. It is known from the Triassic of India.
What does Glossopteris suggest about when these particular continents broke up?
The Glossopteris Plant occurs on the most land masses. This suggests that the climate around these particular continents had been very similar, if not completely the same, and that the Glossopteris had been a common plant back in the days, in addition to it being able to adapt well.
How do Glossopteris fossils support Pangaea?
WEGNER'S EVIDENCE FOR CONTINENTAL DRIFT Evidence from fossilized organisms and mountain chains can be used to reconstruct the positions of today's continents and landmasses to form the supercontinent Pangea. Glossopteris ferns had very heavy seeds that could not move by wind or drift on ocean currents.
What can plant fossils tell us?
Some animals and plant are only known to us as fossils. By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments.
Why was Glossopteris so widespread?
Importance and Extinction of Glossopteris
They were so abundant for so long that accumulations of the dead plants eventually formed massive coal beds that are mined in Brazil, India, Australia and South Africa and also found in Antarctica.
Why are there no Glossopteris fossils in North America and Europe?
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. Therefore, the continents must have been joined at least one point in time in order to maintain the Glossopteris' wide range across the southern continents.
How did the discovery of Glossopteris support?
How did the discovery of Glossopteris support Wegener's continental drift hypothesis? It shows its was spread around in all different continents whose climates are all different now. ... They found more rock, fossils and climate evidence because of today's technology.
What was significant about finding Glossopteris fossils on three different continents?
The wide distribution of Glossopteris on different continents at the same point in the fossil record lent support to the idea that these now-separate continents were once joined.
Is the presence of animal fossils tells that South America Africa and Antarctica were once connected?
Answer: Yes, because these fossils indicated the former connections of the continents before which was called Gondwana in the Triassic Period, 200 million years ago.
Which of the following is an example of fossils found in South America and Africa?
For example, fossils of ancient reptiles called Cynognathus and Mesosaurus have been found on South America and Africa. Also, fossils of the plant Glossopteris have been found on South America, Africa, India, Antarctica, and Australia.
What does the presence of Glossopteris flora suggest about the locations of the continents in the past?
Terms in this set (17)
The occurrence of Glossopteris on landmasses that are now separated by oceans indicates that Pangaea once existed. Mesosaurus and Lystrosaurus fossils have been found in places now separated by oceans.
What kind of organism was the Glossopteris?
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.
What kind of organism was the Glossopteris What did it look like what type of climate did it live in?
Glossopteris is an extinct type of plant referred to as a seed fern. These plants most likely thrived in warm tropical climates.
Did geologist Eduard Seuss points out that fossils of the Glossopteris plant are found in southern Africa South America Australia Antarctica and India?

In what continents do Glossopteris fossils were found What do the Glossopteris fossils tell us about the early positions of the continents?
The glossopteris fossils reflects the evidence of separation of continents like southern Africa, Australia, India and Antarctica which was largely separated by huge and wide ocean which was larlier connected with each other.
Why do true fossils give us the best information about once living organisms?
Living fossils are organisms that haven't changed much in millions of years and are still alive today. Fossils give clues about the history of life on Earth, environments, climate, movement of plates, and other events.
