Hmmm what could this be?

What we know:

My gramma Ang found it on the beach at Cape Bonaventure, Newfoundland. 

It's a partial skull. The jaw is missing.

It weighs 25 g.
It is 79 mm long.
It is 60 mm at its widest point.
The height is 40 mm tall.
The circumference is approximately 64 mm.

It looks like it had incisors and molars, but no canine or premolar teeth.

It also looks like its eyes were on the side of its head.

We guess that this is:

  1. Too dense, heavy and the wrong shape to be a bird's skull.
  2. Not a predator, but prey.
  3. It walks on four legs.
  4. It doesn't eat meat, so it's a herbivore.
  5. Because of it's teeth, we think it's a rodent.
But...we don't know which one!

It could be a water vole, or a rat, or a small beaver, or a marten. We searched the internet, compared measurements and pictures, and we think we are close, but are stuck.

Any ideas? What is your guess?

I'm trying to be a scientist. It's awesome/hard.
