What is a fossil reptile?
Living reptiles include snakes, lizards, crocodiles, and turtles; most of these groups contain members that look very similar to their Mesozoic forebears. Reptiles also include dinosaurs and their descendants, the birds.
Which fossils were found in both Africa and South America?
Mesosaurus, (genus Mesosaurus), early aquatic relative of reptiles, found as fossils from the Early Permian Period (299 million to 271 million years ago) in South Africa and South America.
What are fossils in South America similar to?
Moreover, the fossils in South America are dissimilar to European fossils but have similarities with extant (i.e. currently living) plants and animals in South America.
Which fossils were found in both Africa and South America Brainly?
Fossils of the reptile Mesosaurus have been found in both Africa and South America.
Are reptiles older than dinosaurs?
The earliest amniotes appeared about 350 million years ago, and the earliest reptiles evolved from a sauropsida ancestor by about 315 million years ago. Dinosaurs evolved around 225 million years ago and dominated animal life on land until 65 million years ago, when they all went extinct.
Which animal is known as living fossil?
Horseshoe crab (Limulus) includes marine arthropods which belong to the family Limulidae and order xiphosura. They are mostly found in soft sandy or muddy bottoms around shallow ocean water. Their origin was found 450 million year ago. They are considered as the living fossils.
Is the presence of animal fossils tells that South America?
Answer: A German scientist named Alfred Wegener proposed that all of the continents once had been joined in a supercontinent that he called Pangaea. Wegener found the same rock formations and fossils in Africa, South America, and Antarctica.
Is the presence of animal fossils tells the 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.
Why were fossils of Mesosaurus were found in both Africa and South America?
It would have been physiologically impossible for Mesosaurus to swim between the continents. This suggests that South America and Africa were joined during the Early Permian. It is found as fossils only in South Africa and South America.
How does the theory of plate tectonics explain how fossils of the Mesosaurus were found in South America and Africa?
As the plates started to move away from each other, they started to form new continents, with South America and Africa being two separate land masses thousands of km away, so despite their distance in the present, we have fossils of the same animal in both of them.
Are sharks dinosaurs?
Today’s sharks are descended from relatives that swam alongside dinosaurs in prehistoric times. It lived just after the dinosaurs, 23 million years ago, and only went extinct 2.6 million years ago.
What was the first animal on earth?
A comb jelly. The evolutionary history of the comb jelly has revealed surprising clues about Earth’s first animal.
