This bone was sold to me a while ago and was described as coming from Deinonychus antirrhopus. A little while later, it was simply put as a chunkasaur due to having no evidence of it being theropod. I recently found that there was a hole running straight through the bone that had been filled in by matrix during fossilization. All of the bone skin is also present asside from the broken ends. I think it may be time to reconsider this specimen. Edit: I couldn't figure out how to link the previous post I made on this.

I had found this piece of bone and I think that it might have bite marks. It's from the Lance fm. Here are the pictures. Thanks for any help

So this was the largest bone we picked up on our great Out West trip. We had found it out on a ranch in Montana, as part of the Hell Creek formation. The bulk of the bone was a bit fragmentary, so our guide put a plaster wrap over the top of it. Turns out she just applied it directly to the bone, so I've spent the past few days scraping and scrubbing to get the plaster off. I reglued the loose pieces as they came off, and assembled the fragments that were directly around the bone (during excavation) into 3 medium sized pieces (below). The smaller piece on the right was located *directly* under the large bone. In my dreams this would be a recognizable bone, and one I could make larger by attaching the other pieces to it. Here's the current state: As you can see, it is interesting, and has shape. The socket in the large piece is what caught our attention initially. The smaller piece (right) that was found directly beneath the bone also has a socket. The bone structure in the large piece hints at shape (from the grain and the bits of outer bone that's left), and the small piece has a nice point opposite the socket. The bottom of the large piece (see below) is a nice smooth curve. So...any thoughts? We were leaning towards some sort of hip bone, but feel there are a few other options that might fit as well. Or not at all. We're new to this. At this point, I thought if by chance I could figure out what the shape was supposed to be, that maybe I could better attempt the jigsaw puzzle.
