I was reading the Dino facts for synthethoceros today and one fact said that only male synthethoceros have the fork horn on their nose. This raises the question if all the creatures are female to stop them from reproducing then how do these synthethoceros have their nose horn even if their female. The same thing goes for megaloceros and indricoceros because only male deer have horns. Another thing I have noticed is diprotodon shares its eating animation with the bears arctodus and sarkastodon even though diprotodon is a giant herbivorous wombat it is shown to eat fish. Can someone please explain this. Thanks in advance.
