I found this on my local beach in cornwall. I have no idea what it is.... There has been a lot of storms recently so it's been washed up. Can someone please tell me what it may be? Thanks Amy
This is the skull of a Phalacrocoracidae, Cormorant or shag. Looking at the size compared to your hand I think it is from a shag, Phalacrocorax aristotelis.
I wouldn't have thought it was, judging from skullsite.com, eg http://www.skullsite.com/images/dbimages/large/phalacrocoraxaristoteles_s.jpg
Here is another link from skullsite
Here you can see a shag skull from the top, now break the beak off along the 'hinge' that all phalacrocoracidae have at the base of the beak and there is a striking resemblance to the skull in question.
It is more difficult to do this with the under view of the skull because the skull in question is missing not only the beak but the palatine bones, pterigoids and quadrates.
I'm inclined to agree with the shag suggestion. It appears to be similar to a skull I posted on here last summer when I needed help with it...
Thanks Chris, these were the sort of photos I was looking for on Google. The skull on the skullsite is complete, Your skull is less complete and the skull which started this thread is even les complete. I think having your photos has provided the link
