Hi TFF, I am a Dromaeosauridae enthusiast and have been collecting online for a little while now. I want to thank the members here for getting me educated on so many aspects of fossil teeth identification. I want to share my small collection in the hopes this is helpful for some of you in the future. Your critical input is highly appreciated, as always! #1 First up, one of my treasures, a robust Deinonychus antirrhopus tooth from the Cloverly Fm. A big thanks to @StevenJD for letting go of this one – much appreciated! Note the asymmetry in the placement of the carinae, best noticeable from the top view. #2 Representing the Judith River Fm., a cornerstone of my collection, a 1st left premaxillary tooth of Dromaeosaurus albertensis. I just love the way the mesial carina ‘folds’ onto the lingual surface. #3 Another premaxillary tooth from the Judith River Fm., a Zapsalis abradens with prominent ridges. The mesial carina has a nice twist, the cross section looks rather symmetrical, so likely not a 1st or 2nd premax. Distal denticles are hooked towards the tooth tip, but no mesial denticles are present and the tooth is not recurved. So, for now it is labeled as cf. Zapsalis abradens after Currie and Evans 2019, but could eventually be re-labeled as Saurornitholestes langstoni.

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

So I went to the Black Hills Insitute and I made a lot of photos, so I thought I'd share. The Black Hills Institute museum in Hill City is pretty small, it's just one hall. But this one hall is absolutely packed with stuff. This is also the home of the T. rex Stan. Many of the skeletons are casts, but there are plenty of real fossils here as well. The skeleton of Stan. This is the real skeleton and the real skull is placed beside it in the corner. But I didn't even notice that at the time. Skull of Torosaurus. Notice the holes in the frill. Triceratops doesn't have these holes in it's frill. Tylosaurus proriger. Another real specimen. Two Allosaurus skeletons. An Ornithomimid as well as Stan, the Senckenberg Edmontosaurus mummy and Tarbosaurus skull in the background. Skeleton of Albertosaurus, skull of Albertosaurus on the left and skull of Gorgosaurus on the right. A second T. rex skeleton. And a lineup of T. rex skulls in the background. Thescelosaurus and Pachycephalosaurus. Juvenile Edmontosaurus skeleton below the second T. rex skeleton. Cast of the Triceratops Raymond. Crestless Pteranodon on the left as well as a Nyctosaurus? arm/wing at the bottom. Dromaeosaurus in the middle between the legs of the Triceratops and a primitive Sirenian with legs on the right. Bambiraptor and Archaeopteryx skeletons. Foot and skull of Deinonychus and Herrerasaurus, Dromaeosaurus and Eoraptor skulls at the bottom. T. rex arm (cast of Sue) and brian endocast left. Nanotyrannus skull on the right. Mongolian Dinosaurs. Saichania and Saurolophus skulls at the top. Velociraptor skull and oviraptorid partial skeletons below that. Prenocephale, Oviraptor, Archaeornithimimus and Alioramus at the bottom. Tethyshadros top left, and Psittacosaurus nest, and skeletons on the bottom left. Brontosaurus leg in the middle and baby Apatosaurus on the right. Velociraptor and Protoceratops fighting on the far right. Edaphosaurus skeleton. And this is just a small selection of the photos I took. There's just so much stuff here and I only spent a few hours here. The gift shop is also worth a vist btw. I bought a rather nice replica of a tooth from Stan and a Thescelosaurus phalange.

Earlier this week I received a package in the mail with two very important fossils. Years ago, I owned a gorgeous Bambiraptor feinbergi Sickle claw from the Two Medicine Formation, and a Saurornitholestes langstoni hand claw. I foolishly sold them away to a very good friend of mine back East. I've regretted that decision for years. Well last week I was able to convince my friend to sell them back to me. I sold a very nice fossil claw (something I rarely ever do nowadays since restarting my collection) in order to come up with the money to purchase them. I've been very appreciatively happy that my friend was so generous to allow me the opportunity. I was ecstatic when I received them in the mail and got to finally hold them in my hands again! Daddy got his children back!
