"The horniest dinosaurs were the sexiest"

That has to be one of the best headlines concerning dinosaurs I've ever seen.
Silliness aside, a new article is out about dinosaur sex lives and this one is focused on ceratopsians it would seem. 
This information doesn't come as much of a surprise as, honestly, what other use could some of these utterly absurd headgears be used for? It's all in the name of love haha.

Also in all honesty, I find that Protoceratops'(?) headgear paint job rather unnerving...
