sexing dinosaurs...worse than baby chicks
A paleontologist at the Canadian Museum of Nature is countering decades of studies that assert that some dinosaurs can be identified as male or female based on the shapes and sizes of their bones.
Dr. Jordan Mallon, a dinosaur specialist at the museum, argues instead that the fossil evidence for these distinctions is inconclusive and, as a result, it might be time to "rewrite the textbooks." His report, published today in the online journal Paleobiology, focusses on the biological principle of sexual dimorphism, where males and females of a species can be distinguished based on physical characteristics other than sexual organs.
"I'm not saying that dinosaurs were not dimorphic, but I am saying that there's no existing fossil evidence to suggest that they were. The jury is still out," says Mallon.
