Well well well. To my surprise, there actually is support in the literature for this. The West African Reed Frog Hyperolius viridiflavus has been found to undergo spontaneous sex reversal, though it was from female to male. Otherwise such sequential hermaphroditism is known in vertebrates only in fish. So there actually is a small amount of logic to this one.

Which is funny, because the dinosaurs were ALSO changing from female to male. I wonder why Dr. Grant would say “male to female” in the script.
