In an objective summary of "Pregnant Plesiosaur Fossil May Shed Light on Ancient Animal’s Behavior," I would include key details such as the discovery of the first-ever fossil of a pregnant plesiosaur, the age of the fossil estimated at 78 million years, and the significant finding that it gave birth to live young rather than laying eggs. I would also mention the implications of this finding regarding the social behavior of plesiosaurs, likening it to modern social marine animals like toothed whales and dolphins. However, I would not include extraneous information, such as specific measurements of the fossil or descriptions of its size in comparison to modern objects unless they directly support the main points about reproductive behavior and social implications. The aim would be to convey the essence of the research and its relevance to understanding ancient animal behavior without superfluous details.
"Pregnant Fossil May Shed Light on Animal Behavior" by PBS NewsHour Scientists have pieced together the first-ever fossil of a pregnant plesiosaur, a giant Mesozoic sea reptile from the Cretaceous Era, with an embryo still inside. The animal, which roamed the seas 78-million years ago, is about 15-feet long—the length of a minibus—and bones indicate that the baby plesiosaur would have been as long as six feet when born. The finding, published in the online edition of the journal Science on Thursday, is definitive evidence that the giant sea creature gave birth to single, live offspring, rather than laying eggs, like most reptiles, says paleontologist and lead author F. Robin O’Keefe. This reproductive behavior also indicates that the animals were gregarious social creatures that cared for their young, similar to toothed whales or dolphins, according to the paper. © NewsHour Productions LLC.
