A female dinosaur is called: cow So next time you see a female dinosaur, don't call her a woman! Although people would understand what you mean, it would be more correct to call her a cow. What this implies, in evolutionary terms, is that female T. Rex appears to have been sexually dimorphic in another way: many paleontologists now believe that the females of this species were significantly larger than the males, over and above the size of their hips. At 38-feet-long and weighing in at 7 tons, the fossil skeleton now called the Nation's T-rex will get its moment in the spotlight, as part of the museum's dinosaur hall, which will close for. After ownership disputes were settled, the fossil was auctioned in October 1997 for US$8.3. It was discovered on August 12, 1990, by Sue Hendrickson, an explorer and fossil collector, and was named after her. The only specimen with a confirmed gender (female) is MOR 1125 or B.Rex if you want to call her that, it had also been argued that there's no sexual dimorphism between rexes an the size and the robustness of a T.Rex would depend on the specimen you're using Sue is the nickname given to FMNH PR 2081, which is one of the largest, most extensive, and best preserved Tyrannosaurus rex specimens ever found, at over 90 percent recovered by bulk. How Do You Tell The Sex Of A T Rex - Tyrannosaurus Re The females of large dinosaurs like Tyrannosaurus Rex and Deinocheirus laid relatively large eggs, so their hips would have been configured in a way to allow.

Thanks to the inflexible requirements of biology, there is one surefire way to distinguish male and female dinosaurs: the size of an individual's hips. It keeps birds, and non-avian dinosaurs, from losing calcium when they are laying eggs. rexes ovulate, they create special tissue in their bones called medullary tissue. rex -size eggs and were blessed by evolution with bigger hips The likely reason for this trait, known as sexual dimorphism, is that females had to lay clutches of T. rex outweighed the male by a few thousand pounds. There's a good reason to believe, based on fossils and the shapes of the hips, that the female T. Tyrannosaurus had a much wider range than other. Tyrannosaurus lived throughout what is now western North America, on what was then an island continent known as Laramidia. rex or colloquially T-Rex, is one of the best represented of these large theropods. Tyrannosaurus is a genus of tyrannosaurid theropod dinosaur.The species Tyrannosaurus rex (rex meaning king in Latin), often called T. It is only rarely possible to tell the sex of a dinosaur from its bone tissue rex a male or female? Scientists are not sure if the Nation's T. rex specimens ever found, with approximately 85 percent of the skeleton preserved. rex Pete Larson excavated in 1991, is relatively slim, like our T.

(The bones of a subadult found along with Sue would belong to a male.) And Stan, the T.

rex is slimmer than Sue, it might be that the more lightly built T. According to Frey, that would make our T.
