This is a pretty interesting tooth and I figured I would post it here to get some additional thoughts. This is labeled as an Avisaurus tooth from Garfield County Montana, Hell Creek formation. The first thing that stood out to me was that the shape was a bit different than most teeth labeled Avisaurus that I have seen. Granted I have not seen many but this looked different. It is also close to 1/4" which seems quite large for an Avisaurus. Since there are several Enantionithean birds from Hell Creek, it could be from one for sure but could it be something else? I did some research and found photos on line of a jaw fragments from an Ichthyornis from Kansas that had a similar looking tooth. I am talking general shape really, not saying that is what this is. I also found a comparative study of Hesperornis and Ichthyornis teeth on line and it has a similar shape to one of the Hesperornis teeth in that study. I am very unfamiliar with Avian teeth so I am strictly going by what little research I could find on line. I know there are a couple of Hesperorniformes and an unnamed Ichthyornithean from Hell Creek so it is possible that this tooth belongs to a bird that is not an Enantionithean but I thought this is an ideal tooth to put on the forum and seek some help from those with far more knowledge. Any comments, insights, or thoughts ?
