Aust cliff coprolite, confirmation pls?

[CWS]

Picked this up a while back at Aust in Gloucetershire, UK. It was free but amongst chunks of the bone bed which are full of coprolites with a similar black completion, it also has a smaller piece of coprolite squashed into the side of it. What do you think, is that a big poo?? Found icthyosaur vertebrae very close by too.

Looks like 'it to me. 

I wonder what @Carl will say.

Could be, but I can't see any signs of inclusions? 

There are a lot of phosphatic nodules as well as the coprolites in these beds.

Hi, what do you mean by an inclusion, what would you look for?

Little pieces of what the animal hadn't been able to digest completely. Bits of scale, shell, bone, teeth, that sort of thing. 

They are not always present, but there's usually something visible in coprolites from the Aust Bone Beds.

It's rare, but not unheard of, for coprolites to have septarian cracks. That said, without obvious inclusions, I wouldn't ID this past phosphate nodule.

I've taken a few closer pics, definately a few bits in there one in the first pic looks like a small tooth?

 

I'm also reducing a piece of jaw bone which has a rooted tooth in it, would be interested to know what it's from if you know?

It certainly has details that are quite coprolitic, but without strong indication of organic inclusions I'd still be reluctant to say it's a coprolite. I'm not seeing a convincing tooth in there, unfortunately. I also have no opinion on the other tooth photo.
