Just wondering everyone's thoughts on the I.D of this. Seller states that is was found in the Hell Creek Formation, Garfield County, Montana. Says it was a surface/close to surface find. Measures just a little under an inch straight-line. Theses are the best pictures that were sent to me sadly. Been looking at it myself along with Hell Creek Claw guides and I can't put a finger on it what may be. Still new to identifying things.

Identification of Claws/Unguals from the Hell Creek/Lance Formations
Troodon posted a topic in General Fossil Discussion
A member of the forum asked if I cam put a topic together to help identify claws from the Hell Creek/Lance formation. Its fraught with difficulty since so little has been published and described from these faunas but will attempt to put something together. All subject to discussion and mistakes. Although the focus there is with the dinosaurs of the Upper Maastrichtian its applicable to most of the other faunas of the Campanian and Lower Maastrichtian ages. Ceratopsian indet. This family of dinosaurs include Triceratops, Torosaurus and other large bodied Ceratopsaian yet to be described. Identifying unguals to a Genus/Species level is impossible and these are best identified as Ceratopsian indet. Ceratopsian unguals are best described as being rugose with many pits/holes on the front perimeter of the ungual. There is also a ledge (more pronounced on some than others) on the ventral side as shown by my red marks. I find it difficult to tell the difference between hand and foot unguals of the same size other than the wings are not has pronounced. The more symmetrical the wings are the closer the ungual is to the midline Digit III. Photos are the best way to show what they look like and here are some from my collection Dorsal view Ungual 1 Ventral View Ungual 1 Dorsal View Ungual 2 Ventral View Ungual 2 Dorsal View Ungual 3 Ventral View Ungual 3 An illustration of a Hand (Manus) A photo of a composite foot Leptoceratops indet. A small Ceratopsian in these faunas is a Leptoceratops. Teeth are the most common material found or sold but there are skeletal elements found. Here is an ungual I found in the Hell Creek. The dorsal view is like an isosceles triangle and very compressed. Dorsal View Ventral View Since these are extremely rare here is an additional photo of a associated set of unguals from the Two Medicine Formation An illustration of an campanian foot An illustration of a digit.

Hello all, quick question for you guys who have more knowledge than me. Is this a real raptor claw? Seller states its from the Hell Creek Formation, South Dakota. Pictures are as clear as the seller could give me. Its about .58"/1.4cm. Thanks!

I was given some fossils from Hell Creek, North Dakota. I've been able to find out IDs to some of the pieces but having harder time with bones pieces. So was hoping for any help. Wasn't sure if you can tell bone pieces as dinosaur or not ( or what kind of bones) from photos. A bit to many little pieces to try all but will post ones thought where the better pieces (will try 3). Hoping can at least be able tell if bone is dinosaur or other animal bone. #1 (was sure dinosaur tooth but can't tell which one) #1 (other side) #1 ( side with looks like wear or a broken part) #1 (top or bottom part) #2 (bigger bone piece) #2 (other side) #2 (top) #3 (first side) #3 (other side) #3 (closer view) #3 (closer view other side) #3 (top) #3 (bottom)

A remarkable dental battery of the hadrosaurid dinosaur, Edmontosaurus annectens. Hadrosaurs had highly sophisticated teeth arranged in these batteries which advanced teeth in a conveyer-belt fashion to replace worn ones. Even the roots of teeth were used once the enameled crowns wore away. This one was in active use and fossilized when the animal died. This battery in particular is special, as it was collected by former forum member Troodon, seen in his "My Jurassic Park" thread here. It comes from a hadrosaur-dominated bone bed. -

An enigmatic tooth taxon prevalent throughout the Late Cretaceous. Unfortunately, that means not much is known about the animal that wielded these blade-like chompers. Historically, these have been considered theropod dinosaurs. -

A collection of microscopic (~ 1 mm in size) teeth from the orectolobiform, Galagadon. These are very difficult to collect, as it requires sieving a large volume of sediment and searching the concentrate under a microscope. -
2.7mm long “raptor” tooth found in Garfield County, Montana. Isn’t curved and has serrations. Possibly enat tooth.

Picked this little “thing” up out of curiosity. The fellow who found it was stumped as to what it was. It has rough pointed crown and a base that looks like broken root or bone. The crown is covered black or dark enamel. It resembles a tooth in shape but is very rough. I thought maybe an acid damaged tooth? Never found an image quite like it on any site. It was found in the Hell Creek fm., Montana. Was found along with a few mammal and Dino teeth in an ant mound I believe he said. sorry if photos are not as good as could be. It is tiny.

It's a theropod vertebrate fossil, and I'm curious what type of dinosaur it is exactly. Thank you

Mussel shell fragments litter the matrix, so much so that even in the finest grain size it looks to have been laced with glitter. The original shell material that makes them appear iridescent (nacre) is preserved, which makes it somewhat surreal to sort through - as if this dirt was shoveled from a river yesterday. The colors are more vibrant when they’re damp. Unfortunately they are extremely fragile and crumble if you so much as look at them. -

Under the microscope, one may find these tiny treasures - microscopic shark teeth! They are uncommon and require a lot of effort to find.-

Some bones are so river tumbled that they become rounded, even to a near-polish in some cases, and are referred to as “bone pebbles” in the literature. -

The vast majority of what I find looks like this - chunks of bone and fish bits. In leaving “no stone unturned”, I’ve picked out thousands of pieces of this stuff just to recover a handful of exquisite specimens. -

Identifying features of the troodontid, Pectinodon. The illustration is the holotype, adapted from Carpenter 1982, the color image is a specimen in my collection. These are thought to be anterior dentary teeth; medial/posterior positions lack the lingual pitting, and may have fine serrations at the base of the mesial carina. Carpenter, K. (1982).

Typical Champsosaurus teeth, highlighting distinguishing features. These are commonly confused for gar fish teeth, and similarly Melvius teeth are often confused for Champsosaurus. -
we got a greaaaaaaaaaaaaaat fossil some time ago from a supergreat US-Seller. This was found in Hell Creek, part of THE KING It is necessary to do a little more prepwork on it, but, I have to remove this brown, harder matrix. What is it? Phosphorite? Shells? Or bone? I am not familiar with the Hell Creek Matrix, more with some of the lovely fossils Thanks for supporting! (e.g. what you see on the pics is around 2 x 2 inch), one pic is from the top, one from the bottom, but I would assume this are different whatever, not two views on one thing from two sides
