Identify animal skulls

What animal skull have I found?

Found a bird skull or mammal bone in the UK? Our ID guide below has some of the most common animal skulls you might find. Even if you aren’t able to identify the species you can still tell some really interesting stuff about the animal and how it lives its life. Like a skull detective!

Here are some top tips:

  • Size is a great first clue to the identity - but they may look smaller than you’d expect. When you see the animal alive it’s got fur or feathers on which makes it appear bigger. Different species may also appear the same size. For example, a juvenile rat can be the same size as a mouse.
  • Beak type – try to imagine birds you’ve seen that have that kind of beak. Without feathers covering them beaks can look longer than you’d think.  You might be able to get some clues about what the bird eats from its beak. Is it a thick, short beak for cracking open seeds, or a thin beak like tweezers for picking up little insects?
  • Teeth - herbivores, carnivores, rodents, lagomorphs, and deer, can be sorted by their teeth. But watch out - sometimes the teeth may have fallen out!
