From the album: Hell Creek / Lance Formations
A mammal tooth from the group that includes the marsupials. Found in a channel deposit, it's remarkable that the roots are still intact. -
From the album: Hell Creek / Lance Formations
A river-worn, shed Ornithischian dinosaur tooth found in a channel deposit. Despite its rough shape, the prominent central ridge and denticles make me think it's Pachycephalosaurid. -
Had a great day fossil hunting in the montana badlands, hell creek formation. Found and partially excavated this piece, we're not sure we're going to be able to get back out there to finish the excavation. Our first thought is it's the top view of a triceratops skull with the two brow horns angled down. The right horn in the picture comes to a natural termination, the left looks like the tip is broken off. It looks to be all one contiguous bone. Any collective wisdom what it might be? Apologies for the poor lighting and lack of measuring stick, we were limited out in the field.

Identification Though smaller than many imagine T. rex teeth to be, this is indisputably one. It is characteristically robust, and has chisel-shaped denticles with similar denticle densities on each carina.1 Those qualities support its identification as a Tyrannosaurid, and with the locality information confirming it originated from the Hell Creek formation, this must be T. rex. Comments Like most isolated theropod teeth, this is a shed tooth, likely lost during feeding.2 This specimen has exquisite preservation with the enamel texture sharply retained as in life. It however has minor weathering with possible feeding wear at the tip, light root etching, and the base of the tooth has been lightly smoothed possibly by tumbling in an ancient river (enamel is harder so it wouldn't have weathered as much as other portions of the tooth).

I was looking at some of my small theropod teeth, but I was not 100% sure what the best ID for these two teeth were. Any input or help would be appreciated. These were sold as Nanotyrannus, but very small chance of dromaeosaurid and Aguja dromaeosaurid respectively, but I think they might be Richardoestesia cf. gilmorei. The cross-section of the Hell Creek tooth I think rules out Dakotaraptor, or at the very least, does not match the known morphology. Edit: Oops, I used the really funky side of the ruler I'm using. I was going to use the millimeter side, but ending up using a side that measures 20mm per. The measurements are accurate though as I used calipers for that. Hell Creek Formation; Garfield County, Montana CBL: 6mm CBW: 2.4mm Mesial Density: 8-9/mm [Towards end of carinae] Distal Density: 11/2mm (5.5/mm) CH is a bit difficult since the tooth has heavy feeding wear, but it is 8.3mm tall, but could be significantly higher. The mesial carinae does not appear to extend to the base. Aguja Formation; Brewster County, Texas CH 6.4mm CBL 3.7mm CBW 1.4mm Mesial Density: Possibly worn down, or none Distal Density: 16/2mm (8/mm)

Hey all, Does this 3" specimen from the Hell Creek of Powder River co, MO look like a big node or like a section of dome?

Any idea what this little tooth could be from? It was found in the Hell Creek formation outside of Faith, South Dakota. It has no serrations and the seller says it may be a juvenile richardoestesia.

Hi, A pair of teeth I am interested in. The first one, 1.25 inches. Sold as a dromaeosaur tooth from Hell Creek. Is it actually a Nano? It seems quite big for a raptor from Hell Creek. If a raptor, it would be Dakotaraptor because of the size? Next one is a Tyrannosaur-- just over 1 inch. Is it Tyrannosaur or another large raptor tooth? I have sent seller a message about the exact location -- county and stuff.

Hi everyone, this is my first post on here. This specimen was labelled as a 'dinosaur jaw bone' and it was found in the Hell Creek Formation near Glendive, Montana. It is about 27 mm long. It does seem to me it belongs to a reptile of some sort but I haven't been able to find anything on the internet to identify it with any more specificity so I'd really appreciate your expertise in identifying it. Thanks everyone!

Hi, Am I correct that this toe bone from HCf "near Glendive" Montana is from a turtle? Thanks!!

From the album: Hell Creek / Lance Formations
A rooted Ceratopsid tooth - either Triceratops or Torosaurus (though it's more likely to be Triceratops since it was far more abundant in the HC ecosystem). -
Hi all, I think this toe bone from the Hell Creek in South Dakota has to either be a digit 2 phalanx 2 from a dromaeosaurid or it's probably not even dinosaurian. Please give me your thoughts. Thanks!!

These two fossils are toe fossils from the Hell Creek Formation. Do you know which dinosaur it is?
-
Can someone ID this tooth ? Is it worth buying?
-
I am assuming this is a ceratopsian skull bone, but I am stumped! Can someone help me with the ID? Ceratopsian anatomy isn't my specialty. Excavated from mudstone in the Hell Creek Fm. Slope Co. North Dakota Any help would be greatly appreciated! Thanks in advance!

This is a fossil seed I got from the Hell Creek Formation (Montana) last year. Would you say this is a species of Marmarthia or some other plant?
