The chance discovery of large fossil specimens in a museum drawer has led researchers to conclude there was a gigantic marine reptile swimming the seas 152 million years ago, a study finds
The chance discovery of large fossil specimens in a museum drawer have led researchers to conclude there was a gigantic marine reptile called a pliosaur swimming the seas 152 million years ago, according to a recent study. The findings from the Late Jurassic period, though fragmentary, suggest the pliosaur was about twice the size of a killer whale — and move lead study author David Martill closer to redemption.
“It isn’t out of the question that pliosaurs may have exceeded 15 metres long,” Smith said via email. However, he cautioned that an increase in length corresponds with an “exponential increase in volume … placing a biological limit on the upper size pliosaurs could reach.” Smith wasn’t involved in the study. Pliosaurs were “a group of large carnivorous marine reptiles characterized by massive heads, short necks and streamlined tear-shaped bodies,” according to Britannica.
