Very nice! Great photo.

What makes you say it's likely male? Is it the crests? You have me looking for a wang now xD

I remember staring up at that one with a face mush like; O_O

I love Allosaurus, and seeing the full size, even without muscle and skin was so amazing. XD
I loved that whole museum.

The trick is to look at the tail bones. See how in this picture the little bones sticking down from the tail bones are all about the same size close to the hip?

And in this photo (which is of a T. rex, facing right) the first few little bones are smaller and bent backwards a bit? http://pro.corbis.com/images/PG990714.jpg?size=67&uid=%7B7A0162AF-9C35-4579-A42D-69BBF877B722%7D

The theory is that, like in crocodiles, female dinosaurs had the smaller first few bones to allow the eggs to squeeze through the cloaca more easily. I checked, and the Smithsonian allosaur had same-sized tail bones, so he's probably a he.

Oho! The more you learn! Thanks! 8D

gotta go there one day :)

interesting how it's lower teeth end at some point while the upper go on extensively

Yeah, Allosaurus had a very weak bite but strong head and neck muscles - one theory is that it opened its mouth extremely wide and sawed through the flesh with the upper jaw, like so: http://upload.wikimedia.org/wikiped....._Steveoc86.jpg
