Trying to ID this skull in my collection. I initially thought it was a grey squirrel, however, when i compared it with a grey squirrel, I could see that it was quite different (slightly longer and broader, and of denser bone), although i believe sciuromorph. Unfortunately i have no idea where it came from (could have been collected overseas or found in Wiltshire garden - dead pet ?).
Help much appreciated.
It is indeed a Grey Squirrel skull. Not Red Squirrel anyway (compare here). Take a look at the Grey Squirrel skull images here. They have other photos too. You could take a new set of 3 photos: from above, from below, and from a side, but really perpendicular on that plane you want to show (see what these photos look on that page). Then, compare with their photos.
All the best,
Thanks bombuslucorum, I had also thought it could be some kind of ground squirrel / marmot, but could not find enough good images to compare it with. Here's another view of the above two skulls showing the occipital region.
and one showing detail of the zygomatic arch
It has a very pointed corner unlike some images I have found of what I believe to be alpine marmot skulls.
Thanks once again for the input.
OK, have done a bit more digging around and Black-tailed Prairie Dog, Cynomys ludovicianus, looks like a dead ringer - so we were in the right ball park (just wrong continent).
Have a look at thgis link and scroll down to page 283. - see what you think.
