This week I have the first of what I hope will be many mystery objects from my new job as zoology curator at the National Museum of Ireland:

I haven’t quite got myself a proper photographic set up yet, but I hope this photo of an unidentified skull in the collection will be good enough for you to be able to help me work out what species it belongs to.

As usual you can leave your thoughts, questions and suggestions in the comments section below. Have fun!
