Jurassic fossil gives missing link in crocodile family tree
A study of a 180 million-year-old fossil has uncovered how some ancient crocodiles evolved into dolphin-like animals. Some Jurassic-era crocodiles had armoured bodies and limbs for walking on land while another group had tail fins and flippers. However, this species was armoured and also had a tail fin, suggesting it is a missing link between the two groups, said researchers.
