I have a great guest mystery object for you this week. It comes from the wonderful Catherine McCarney, who is manager of the Dissection Room at the UCD School of Veterinary Medicine:

Here’s what Catherine has to say about it:

This object is a bone fragment from an unknown animal. It was discovered while cataloging an old box of historic specimens in the UCD School of Veterinary Medicine. It’s of limited use in the vet program, but my Zoologist background is keen on answering the mystery rather than simply discarding it. It has me stumped, it’s light weight (just 26g) had me thinking it must be from a bird, but some features are reptile like.

So, do you have any thoughts on what this mystery object might be?

As ever, you can leave your thoughts, questions and suggestions in the comments box below. Happy sleuthing!
