I don’t normally go in for these types of posts but I did think this one would be genuinely interesting after the item in question turned up in my office. It’s obviously a mould / cast of something, but what? I will say it’s connected to my research and a published paper which is a small hint.
I’ll reveal all here on this post in a day or two.
And all is revealed. Well done to Matt who got this right and props to Adam who was very close right off the bat and220mya who was nearly right. This is indeed a positive mould made of the Tarbosaurus feeding traces I described last year. This shows a number of sub-parallel tooth marks having been dragged through the surface of the bone and a second set lying at an angle to the first. Thanks for those taking part.
