I've compared the skull of _A. jimmadseni_ and the one of a young allosaur
and I agree, it looks like a young animal: the snout is quite thin.
It appears to me that the lacrimal of _A. jimmadseni_ looks more rounded
(but the photo is small).
Could there be an intraspecific variation in the form of _Allosaurus_
lacrimal (let's say for example in A. fragilis)?
