A few years ago I spotted this Allosaurus on display in Japan. As you can see, there appears to be a dent in the scapula surrounded by a ridge of bone. This too me looks suspiciously like a pathology of some kind but the skeleton on display is a cast and I don’t know what specimen it’s based on. I’ve had a quick flick through the literature and while there have been papers on Allosaurus pathologies I’ve not seen anything on the shoulder brought up before.
So this post is kinda two pronged – first off: cool an Allosaur pathology! And two, if you’ve seen this exact one before, can you point me to the specimen number or even a paper describing it?
