  1. Avisaurus tooth?

    Unfortunately, cant get better pics. But hope these are ok. Avisaurus, Hell Creek, 6mm. Seller said there aren't serrations. Thanks
  2. Hell Creek Avian Tooth

    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 ?
  3. One of the stated goals of Fossils on Wheels is making contributions to science. it will be in the charter when we have finalized our 501c3 and it will be part of our mission statement. My son and I believe in this idea as much as we do in the education pursuits. I recently contacted a very well known Paleontologist who has made some ground breaking discoveries in the world of avian evolution. I wanted to pick her brain a bit and I told her a little about we are doing. i happened to mention we just got a small "Avisaurus" tooth for our program. She informed us about a research project to study Avian teeth and let us know we could contribute to that research. She did not ask or put any pressure on us. She was super cool and understood if we did not want to do it. It was just a suggestion. I searched pretty hard to find a bird tooth for our program and we have barely gotten to use it but that little tooth may be our first real contribution to the Paleontology realm. It took me 1 second to head to my son's room and ask him what he thought. He agreed with me that it was worth doing. We both loved the idea actually. Obviously my hope would be for the tooth to be studied and scanned then returned to us which may be a possibility. If it turns out that this is indeed a potential bird tooth, we will be sending it to the researchers. Little is known of Cretaceous bird teeth. If we can help further that knowledge in any way, we want to be part of that. So we may not have a bird tooth to show the kids but we will have a story of about one of our teeth contributing to real scientific knowledge which is something to be proud of
  4. I do not want to brag but I am going to just a little We did our note taking dinosaur adaptation program yesterday and it was really pretty awesome. Every kid in both classes took notes and they were among the most engaged students I have ever worked with. I already knew these kids from an earlier shark presentation so they were really pretty excited. They knew their dinosaurs but we were able to expand their knowledge and get them excited about new dinosaurs. We will be doing more these dual standard programs next year for sure. This was also the first presentation i had done where I got to work in information about the evolution of flight that came directly from one of leading experts on this subject in the world, Jingmai O' Connor. I had the pleasure of getting some information from her via email and it paid off in the form of more accurate information. This was also the program where our tiny Avisaurus tooth made its debut and it may be the last appearance for that tooth before it goes on a journey of scientific importance in the near future. Our program was so good yesterday that the students want us to come back to their classroom for round three before the end of the school year !!!
  5. Hell creek small theropod bone?

    I was recently going through some old finds from last summer when I came across this little bone, it is partially hollow and has very porous bone structure. that's why I assume this bone came from a very small theropod. It shares some resemblance to a bambiraptor coracoid as shown in the last picture and is almost exactly the same size. the bone measures 11mm wide in the first picture
  6. primitive bird fossils

    I really really love primitive birds and would love to see your primitive bird fossils, with scale if possible I only got a couple myself but would love your opinions!
