Hello! Today, I’ll write about Cenozoic animals.
Pakicetus attocki is the early whale that walked. It isn’t similar to modern whales, but there are same points in ears.
Dorudon atrox is the early swimming whale. It is similar to modern whales, but it has small hind legs and structures of fore legs remain in its flippers well.
Aetiocetus polydentatus is the early baleen whale, but it has teeth in place of baleen.
Mixocetus sp. is similar to modern baleen whales. This skull looks like a surfboard.
Paleoparadoxia tabatai is one of the unique prehistoric animal in Japan. It may be one of the most mysterious mammals ever lived.
Chilotherium anderssoni has a pair of tusks in the front of lower jaw. I think they were used for digging roots (It’s only my thinking. You shouldn’t believe.).
Platybelodon grangeri has the long lower jaw like a shovel. I think It’s one of the most unique elephants ever lived.
Thank you for reading! Next is the final time. I’ll write about extra place in next time.
