DEENA: We're almost out of time. Any secrets you'd like to share with the folks at home?
PROTO ANDY: Here's a shocker. Based on my bones, scientists can't tell if I used to be a dino-guy or a dino-girl.

One has a low face and inclined frill, and the other has a deeper snout with a small horn-like bump above the nose and a more vertical frill. Unfortunately, it's impossible to know for sure which skull is male and which is female.

See you next time.
