On Friday I presented you with this skull for identification:
Quick as a flash SmallCasserole had it identified and discussed and not long afterwards Jake also managed to identify it as belonging to a hippopotamus. The large size and characteristic flaring out of the maxilla to house the tusks was a dead give-away.
Hopefully this Friday we can move away from skulls and give you a bit more of a challenge!

I worked it out because my dad said it was a skull I knew, and because I could see it was big so I went through a load of skull pictures to work it out.
