I recently visited the Australian Museum. Unfortunately we only had about 3 hours there – which was a shame, as I know I could have spent a whole day there.
This was an open display (huzzah, no glass case!) and even though they were probably a cast, it was still quite amazing to look around and know that these bones were once massive creatures. It was almost humbling.
They are, of course, Tyrannosaurus teeth. I was quite proud how it turned out, especially considering the low light conditions.
