Fine layers in siltstone, "rhythmites", potentially due to tidal influence from the nearby coast? Cleaving along the dark layers reveals organic planty material. -

A seed from an extinct palm tree that grew in the forested, coastal floodplains of northern Laramidia. This fossil was recovered on state-owned land under proper permit, and is not a part of my collection. -
Hello, as my budget increases, this complete surface find and worn Tyrannosaur tooth comes very close. But its listed as Nanotyrannus, and not Rex. But after I've read a guide on Tyrannosaur teeth idenification, im pretty sure its a young Rex, as im not seeing the typical Nano pinch at the base, but I think the tooth is also too bend for Rex. Which side are you on ? Sice : 1 inch Formation : Hell Creek, South Dakota, and before you ask for the County : Sorry, but no County was named. @FB003, @North, any Ideas ?

These large lizards are kin to modern monitors like the Komodo dragon. The possess sharp, finely serrated teeth and long claws good for climbing and digging. They likely preyed on smaller animals like other lizards and mammals, and may have been the bane of parent dinosaurs as some paleontologists have suggested they could raid dinosaur nests. Varanoid “monitor lizard” fossils. A) trunk vertebra, missing a good portion of the process; B) tooth showing basal cross section silhouette and closeup of serrations. -

I found a few holostean-grade scales that haven’t been attributed to more precise taxa, and are referred to as holostean “A” and “B” in the literature. These are not gar and are something else. -

Lonchidion was one of the last of the hybodonts, a lineage of shark-like fishes spanning nearly 300 million years before they went extinct along with the non-avian dinosaurs. Lonchidion had barbed spines on their dorsal fins and a durophagous dentition more suited to grinding than grasping. Like most hybodont teeth, their roots are fragile and their teeth are only rarely found complete. In this deposit they seem to be fairly rare; I’ve thus far only found two. -
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)

From the album: Hell Creek / Lance Formations
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.
