Rat?

Another little skull to add to my collection! I found it on the beach today while looking for groatie buckies (cowries) and I'm pretty sure it is from a rat. There is something very beautiful about tiny delicate bird skulls and ones from little rodents, such incredible architecture and the intricacy where the various plates meet.

Ollie wasn't very impressed and went and had a swim while he waited for me! I had to take photos of it on the shore in case it fell apart as I carried it home!
