Dinosaurs Inside and Out

Growing Bones

Can you tell the difference between male and female dinosaurs from their bones?

No, it is really not possible (at present) to determine the gender of a dinosaur by looking at its fossil bones. There are few clues to determine a dinosaur’s gender, although some scientists believe certain species may have had features that distinguished gender. For example, hadrosaurs (duck-billed dinosaurs) sported certain types of bony head crests, but just which gender had the crest is unknown. Currently, scientists are trying to base dinosaur gender ideas on examples from today’s animal world, and even then it’s still almost impossible to determine a male from a female dinosaur.
