Paleontologists have devised a new method to distinguish male from female dinosaurs, according to a paper in the latest issue of the Journal of Vertebrate Paleontology.
The technique, which involves analyzing upper-hind limb bones, may help to solve this long-standing male or female anatomical mystery, since the remains of dinosaurs today are not fleshed out with soft-tissue genitals....
... Paleontologist Ralph Chapman, an owner/partner at New Mexico Virtualization, has also studied dinosaur fossils with sexual dimorphism in mind.
Chapman told Discovery News that the new study "pretty much achieves what they say it does and I think it is a good paper." He pointed out that the ends of femora fossils might be particularly revealing, in terms of identifying differences among dinosaurs.
