Dinosaurs Grew Fast and Bred Young

Posted by kdawson on from the dinosaur-named-sue dept.

Smivs writes "It is thought that dinosaurs were able to breed before they were fully grown, much like todays mammals. This ensured that they could breed before they were predated in the violent world of the Mesozoic era. Calcium-rich medullary bone, which, in birds, is used to produce egg shells, was found inside the fossilized shin-bones of two specimens: the meat-eating Allosaurus and the plant-eater Tenontosaurus.Sarah Werning and Andrew Lee of the University of California, Berkeley, deduced from growth rings inside the bone that the two females were aged eight and 10, very young for dinosaurs, which lived to about 30. 'This shows us beyond any doubt how fast dinosaurs grow,' said Kevin Padian, a professor at UC Berkeley's Museum of Palaeontology. 'They're growing as fast as big birds and big mammals.'"

    Now this doesn't mean they are giving birth to kids but they are sexually active and those are just the ones with HIV.


    Or that they were born to parents that were HIV positive and contracted it at or before childbirth...
