What is a Glossopteris fossil?
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 fossils were found in South America and Africa?
Remains of Mesosaurus, a freshwater crocodile-like reptile that lived during the early Permian (between 286 and 258 million years ago), are found solely in Southern Africa and Eastern South America. It would have been physiologically impossible for Mesosaurus to swim between the continents.
What do the Glossopteris fossils were found in Antarctica?
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.
Do the Glossopteris fossils tell us?
Answer: Yes. Because they indicate biological identity of these plants that were critical for recognizing former connections between the various fragments of Gondwana: South America, Africa, India, Australia, New Zealand, and Antarctica.
Is the presence of animal fossils tells that South America Africa and Antarctica were once connected?
Many scientists thought that Africa, India, Australia, South America, and Antarctica had once been connected into a large ancient continent known as Gondwana. Those fossils belonged to a species previously found in Africa, providing further evidence that the distant present-day continents were once connected.
What evidence shows that Africa and South America were once connected?
To him, the presence of identical fossil species along the coastal parts of Africa and South America was the most compelling evidence that the two continents were once joined.
Why are Mesosaurus fossils found in South America and Africa?
The fossils of this prehistoric reptile have been discovered in eastern South America and southern Africa, and since Mesosaurus lived in freshwater lakes and rivers, it clearly couldn’t have swum across the expanse of the southern Atlantic Ocean.
Which animal was found on two continents even after it went extinct?
Eight species of pangolins are found on two continents. They range from Vulnerable to Critically Endangered.
How much does a pangolin cost as a pet?
This makes it clear that their businesses are booming and that they can afford to splurge. They pay up to $1,000 for a live pangolin and $300 per kilo for the meat.
Why do they kill pangolins?
Tens of thousands of pangolins are poached every year, killed for their scales for use in traditional Chinese medicine and for their meat, a delicacy among some ultra-wealthy in China and Vietnam. There are eight species of pangolins. All species face declining populations because of illegal trade.
Are pangolins illegal in China?
The Chinese government continues to allow the use of pangolin scales for traditional medicine despite promises to crack down on a trade that has made them the most illegally trafficked mammals in the world.
Is it legal to own a pangolin?
If pangolins are protected as endangered under U.S. law, the import and interstate sale of all pangolins would be prohibited in the United States, unless such activity can be shown to promote the conservation of the species.
Can we ban the sale of pangolins?
If pangolins are protected as endangered, the law bans import and interstate sale of pangolin parts in the United States, except for scientific or other conservation purposes.
How many pangolins are left in the world today?
They are seldom seen in the wild, and are very hard to raise in captivity. Yet, pangolins have become the most heavily trafficked wild mammal in the world. Up to 200,000 are estimated to be taken from the wild every year across Africa and Asia.
Did Covid come from Pangolin?
Continued. Study co-author Donald Benton said, “We still don’t have evidence to confirm the evolutionary path of SARS-CoV-2 or to prove definitively that this virus did pass through pangolins to humans.
