Therizinosaurus mating

[Brachiosaurus]

I have a theory of how Therizinosaurs might have mated. I think that they might have used Leks like many species of grouse do today.

That's interesting. What makes you think they might have used leks and not some other kind of mating strategy? More importantly, what evidence would your theory predict, that we could look for in fossils?

- and adding to Dinoguy's post, why Therizinosaurus?

I've been taking North American Wildlife at my college and for some reason these Grouse just reminded me of therizinosaurs, I think its because of how chunky they are

It would probably predict some size dimorphism, but we'd need a lot more specimens than we have.

leking and lek like behavior has been postulated for several other Maniraptoran Dinosaurs. From Saurornithodes (spp?) in this one book I once read, to Dinosaur Revolutions comically over-the-top Gigantoraptor mating dance.
