Friday mystery object #101

Although last week I hinted that I may stop the mystery object, I’ve decide to try out a different system. Rather than give an extended answer on Monday (a time-consuming business) I will simply provide a very brief answer. Hopefully this will free up some time to do other things.

This week I present you with another partial piece of skull that I recently reunited with the rest of the specimen it came from. There’s no scale bar to keep it challenging!

Any idea what this is?

As usual, you can put your suggestions, comments and questions below and I will do my best to answer. Good luck!
