More recently, researchers have identified early forms of whales, including Ambulocetus, which has been called a ‘walking whale’ because it was able to walk on land.

of a sea creature found in the Arctic Skeleton Has surprised the scientists. Researchers have speculated that this may be the oldest fossil. Significantly, the scientists engaged in the research of fossils had estimated that 250 million years ago, there must have been the most primitive form of any organism. But it has changed the perception of scientists. Scientists have started research from a new end.
whale-like Ichthyosaur Scientists are bewildered after seeing the fossils of. Although scientists have not yet given any special name to it. Scientists have found that his shape suggests that he must have been physically advanced in his time.
was prosperous even in the time of the dinosaurs
Scientists believe that the ichthyosaurs were an active group of marine creatures that dinosaur Must have been prosperous during his lifetime. He was about 70 feet i.e. 21 meters tall. Whale is considered to be the largest creature in the oceans but it must have been bigger than that.
Scientists say that its origin seems a bit mysterious. They have found the remains of the earliest known ichthyosaur, which lived nearly 2 million years after it was extinct from Earth. Who endured the Siberian volcano on a large scale. Even after this he kept his life safe. That is, he was able to withstand the most difficult situations.
progenitor of the oceans
It has also been learned that he was a mammal like a whale and was the ancestor of all the creatures living in the oceans. Scientists say that its existence is full of surprises. He’s been a fast grower. His blood must have been very hot. He is a creature living entirely in the ocean.
The place where the fossils were found is an arctic site with high snow-capped mountains along the coast. 250 million years ago, fish, sharks, shelled squid-like ammonoids and crocodile-like marine creatures called temnospondyls lived in the ocean.
some even looked like dolphins
Scientists believe that their mass extinction affected the earth and marine ecology. New species opened up new opportunities to fill the places vacated by extinct organisms. Ichthyosaurs lived until about 90 million years ago.
Many ichthyosaurs looked like dolphins and some looked like big whales. The largest Ichthyosaur was about 70 feet i.e. 21 meters. They used to eat fish.
There are many implications of this discovery. Most importantly, there is an indication that these were in the formative years of dinosaurs. However, the oldest known dinosaurs did not appear until about 230 million years ago.
