@turgon

A squirrel would be a good guess, but I know there are thousands of dessert pack rats and desert kangaroo rats and a few jack rabbits in the area, but I've never seen a squirrel.

@turgon

I thought it was a desert kangaroo rat, but I'm rethinking that. Perhaps it a rabbit.

That pelvis, though...seems too small for the jaw if it's a rabbit.

@marc_w @rbmath the pelvis is surprisingly difficult. I thought it wasn't a rabbit because the examples I found had quite long ilia. it occurred to me just now that yours might have lost its ilia, which seems more plausible for a rabbit. I'm no expert! just leaning heavily on one semester of classical archeology here

I had guessed squirrel mainly by the size of the jaw, femur, and the length of that bit of fur.

@turgon @rbmath

I thought it was a desert kangaroo rat, but I think you're right. It was probably a young rabbit.

@marc_w the teeth make me think rabbit... But I'll admit I'm not great at my skeletal anatomy

@rbmath It’s a rodent. If it helps, it’s from the Anza-Borrego desert east of San Diego.

@marc_w unfortunately that does not help, I'll wait for someone else with more knowledge to respond
