The female dinosaurs were bio-engineered with DNA from both amphibians and reptiles. Quite frankly, the female DNA from the amphibians had mutated so the dinosaurs changed sex. Fish can do the same, such as clownfish. For all we know from Finding Nemo, once Marlin's significant other died (if the lead female in a school of fish dies, a male can change its sex to female and take over that role that's left open), he could have changed into a female, so that's why he was PMSing throughout the movie about finding his son, Nemo.
