From the album: Hell Creek Formation Microsite
Acheroraptor was a small theropod (dromaeosaurid) "raptor" that lived in the same paleo-ecosystem as T. rex. Its blade-like serrated teeth possess diagnostic apicobasal ridges.-

Gars are predatory fish, armored with diamond-shaped scales coated in a hard enamel-like substance. -

Myledaphus (a guitarfish/ray) teeth are quite common, as expected for a riverine deposit. -

Sections of ossified tendons from ornithischian dinosaurs. Especially in an energetic channel environment, these fragile structures are broken into pieces. You’ll notice the surfaces and ends of several of these are rounded from river transport prior to final deposition. -

ah so hello friends its been a while I recently bought and found a whole bunch of fossils
jcorradino posted a topic in Fossil ID
I do have more, but I can't upload them all; it's a decent bit of stuff. Also, I want to know if I should give any to researchers. Most of these are either from the Morrison Formation or Hell Creek. also 1 is from NY in these few anyway -
T. rex or Nanotyrannus tooth?
Tressmeister posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello, I am trying to identify if this is a T. rex tooth. It's described as "natural juvenile Tyrannosaurus tooth". Location: Hell Creek Formation, Montana. Dimensions: Height: 4.3 cm Width: 3.8 cm I've read this awesome post by troodon, and I'm leaning towards T. rex ("fat" and rounded tip) - but looking forward to seeing your opinions as well. Thanks and have an awesome day ahead!

Sellers says this is a Trex vert from the Hell Creek Formation. Any way to tell the difference between a Trex and a Herbivore? @jpc @hadrosauridae

Hello all. 👋 Looking for some advice. I have some hell creek fm dino bone I would like to clean up but it has spots of lichen and iron. I tested some hydrogen peroxide in a small area and it seemed to clean up the iron. My question is if it will react with the "bone" material. Maybe soak it in HP or even Iron Out? Been a while since I took chemistry so I'm not sure about the interactions. Also, what is the best way remove lichen? Thank you in advance.

A pile of hundreds of small Myledaphus teeth, recovered from a channel deposit in Montana. -
During my trip to the Hell creek formation of South Dakota last year, I found this large rib weathering out of a hillside ("cliff side" is a better description). I jacketed what was still in situ, and collected all the surface float at the site, and at the bottom of the cliff it was in. The length in the jacket was 32 inches. Can't determine which species this rib belongs to, most likely from Edmontosaurus or Triceratops, but it will have to remain indeterminant. After removing the excess matrix in the jacket, I discovered that the rib was far more fractured than I thought. Because the rib ended up being pinched by the jacket, I had to remove it in sections instead of a single piece. That worked out for the best anyway, for prepping it in my blast box. I have 40 hours into the removal and gross cleaning of the sections. Another 10 hours and still counting for separating all the breaks and cleaning out all the matrix in between bits so that everything can be reassembled properly. It looks like the rib has a healed fracture, but of course, one of the modern breaks goes through the remodeled bone. The jacketed portion looks to be the main shaft of the rib, only missing a few centimeters of the distal tip, based on the the end has thinned and flattened. The collected float should be the majority of the head, but reconstruction of that will be much harder. I wish I had a cast of a complete rib head to correlate the bits of float to their original position.

Distinguishing Borealosuchus and Brachychampsa teeth
Othniel C. Marsh posted a topic in General Fossil Discussion
Is there actually any means of distinguishing Brachychampsa and Borealosuchus teeth, particularly those from the Hell Creek Formation? Insofar as I can see Brachychampsa teeth tend to more globular than those of Borealosuchus, but I have noticed that some Brachychampsa teeth, particularly those closer to the back of the jaw, can be quite elongate, so is there an identifying feature besides shape? -
Hi, thoughts on this? The base looks Rexy, but the tooth is quite thin rather than fat, so I am thinking it might be Nano, not Rex? Any thoughts would be great. 1.2 inches, from Powder Rivery County, Hell Creek

Hello, I am interested in this. A Ilium bone from south Dakota. 23 x 10 x 5 cm. Is anyone able to tell that it is a Pachycephalosaur or is it a different dinosaur? thanks

Howdy all, I've had this salamander vertebra from the Hell Creek Formation for quite some time now, and I was wondering if there would be any way to place an ID. (I've been told it could be either Scapherpeton tectum or Habrosaurus dilatus)
