Hi All, Curious to know if this hunk of chunkasaurus from Weston county Lance formation can be place in a family. Also, I marked a set of holes along the top to see if you think they could be tooth marks.

Hi all, My son and I recently got the incredible opportunity to live the dream and break into rocks from the Lance formation in Wyoming ourselves in the comfort of our own living room--thanks to a special member on TFF ! We came across this Chunkosaurus piece last night. If there's enough material here to ID (even just the family it comes from), we'd be thrilled to hear your thoughts. In my novice eyes, it looks like it may be a chunk from the perimeter of a Triceratops frill. One typically expects to see the curvature at the perimeter of the frill having the opposite orientation (i.e., convex vs concave?), but I included a picture of a frill right below and circled some examples that support the possibility of this ID. Thanks!

Wanted to see if anyone can ID these chunks of bone I’ve found in the Peace River. They’ve all got somewhat interesting shapes so I figured IDs might be possible! 1) 2) 3) Any help is, as always, appreciated!

It is with a good bit of giddy enthusiasm that we share our very first Jurassic dinosaur fossils. We have a start to our Morrison Formation collection and I am so excited to take these into class. This is also a proud moment because my son and I earned these fossils with our hard work. This is a gift to our program from us and a gift to the kids we want to educate. They are also big hunks of dino bone. We needed a couple of larger bones for these programs for visual flair and these fit the bill for our budget. It will be a week before they arrive but I am too excited to wait lol One of the things we learned from our first dinosaur program was that 2nd graders learn about Diplodocus when they study dinosaurs. It was a species they knew. So we purchased a partial Diplo coracoid bone. It is a 15" x 11" x 9" hunk of dinosaur bone that weighs 12 lbs. Our largest and heaviest fossil. This one will really get the attention of the kids I think and gives us a the opportunity to feature Diplo in the program We also added two partial Camarasaurus ribs that fused together during fossilization. It is 14" x 9" so it is good sized and is a great example of the geological process they are learning about. This gives us an additional Sauropod to cover in the program and lest us talk more about niches. This will be a great fossil for the kids to touch as well. We are also adding a few pounds of chunkasaurus bones. Perfect dino fossils for hands on exploration and a few special give away dino bones too. The pictures are not great, not sure why but I will upload more when they arrive. Here are the big ones.... Picture 1- Diplo coracoid Picture 2 Cam ribs

For the most part I am pretty happy with our collection so far and pretty satisfied with the fossils for our presentation. I know we are lacking a couple of items that kids will really dig. I am working on picking up a low quality, cheap Tyrannosaur tooth that the kids can handle. I know that is something kids will LOVE. I am close to having a Jurassic sauropod bone so we will have something soon that represents the massive size of a dino. Beyond that, I know what I want to add but not the order. Most of the next round of purchases will be bone not teeth. Dromaeosaurid teeth are an exception but the next few additions really need to be bones. Part of why kids dig dinosaurs so much is they were huge animals. Bones give a much better representation of that size than teeth do. I picked up on the basics of identifying dinosaur teeth pretty quickly but bones are a different. I am working on a basic anatomy lesson on dinosaurs for myself. I study for about a half a night as that is all the time I have right now. Feeling okay about basic dinosaur anatomy is a good thing but learning about the fossil bones as collectibles is pretty scary. I see bones all over the place so I am not worried about finding them. It is EVERYTHING else about that worries me. Figuring out if they are even dinosaur bones is pretty hard for me at this point. I see bones that look to be chunkasaurus to me but are labeled with a species. I also see a lot of fragments that have not only have species but are labeled as ribs or verts or limb bones. Where are the ID"S coming from? How does anybody know that fragment is a Triceratops limb bone? To me it seems a clear cut case of dealers wanting a species to move product. I get why it occurs but it is not helpful. For somebody new to this, it is pretty crazy to see so many bones with species attached. I avoid most of the bones I am seeing right now. I simply do not trust my knowledge and I do not trust a lot of what I see. I have taken to assuming most of what I see is not identified correctly. I may not know a lot about dinosaur bones but it has to be snarge near impossible to ID a fragment of bone to species level or even family level. This makes it hard to trust peoples identifications when it comes to bones that are probably more diagnostic. I am doing my best to study my bones and I am putting in the time to really increase my knowledge. I have already learned not to rely on dealer ID's but the bones take time to learn. Each dinosaur is different so you have to know quite a bit. I made a list of the bones we want to add and I study those 5 or 6 which I find helpful. I avoid impulse buys and I am very cautious. I will also use the forum more before I am ready to buy something. I plan on posting bones I see come up and get more informed opinions and developing resources. I have a few dealers that I do trust so that will help too. I think for the bones, developing connections and fostering relationships will be really helpful but I am still finding sources for fossils so my connections are limited. My advice to my fellow newbies is go slow and learn as much as you can. Invest your in knowledge before you invest in the fossils. Be careful and get ID's verified before you buy. I wish you all luck in your collections and good luck with dem bones

I saw this for sale and this would be perfect for our program if they are dinosaur bones. I am not well versed in bones yet and some of these look very interesting. The bone in the lower left of the picture and the larger one to the right of that both caught my eye. I do not know what they are and I did look at some pictures before I posted it but I could find much in the way of help for myself so I thought I would put it to the forum. If they are dino bones, this would be a nice addition so if you have a thought on what these might be, please share ??
