Identifying Theropod Teeth from the Judith River/Two Med Formations
Troodon posted a topic in General Fossil Discussion
Identification of theropod teeth from the Judith River and Two Medicine formation is always a challenge even for the more experienced collector. Sellers whether its a dealer or auction site also struggle with identifications and sometimes just shotgun it. So I decided to put this together as an quick aide in providing you some information. Among the sources used is the reference book Dinosaur Systematics by Ken Carpenter and Phillip Currie... its an excellent reference source. This aide is for the more common teeth collected and sold, not for more obscure theropods. I'm sure mistakes/omissions- 6 replies

From the album: Westphalian cretaceous fossils
One of my mostly loved sponges, Becksia soekelandi. Fragile, thin, hard to prepare. But..., always very cool. Comes from the lower Campanian of Coesfeld, same locality the Coeloptychium comes from. Height around 8 cm© fossils worldwide

I recently acquired some matrix via trade from @will stevenson. This matrix is from Hallencourt France. Just the second time we gotten to go through the entire process of breaking down matrix to a searchable form. I am still in the process of breaking it down and only have searched probably less than 20%. I wanted to begin the post now as I had a few minutes to write. The material is Early Campanian in age and from the North of France. Unlike my first experience breaking matrix down which was from a location with no publication, there is a publication.

Baculites scotti. Found near Wasta, South Dakota, USA. In the Pierre Shale Formation. Upper Cretaceous - Middle Campanian. Approximately 45 mm. -
Recently visited the Green Mill Run area in NC and found some fossils that thought would peak some interest but need the help of identification. I know the site can have a bit Cretaceous but also Eocene and Pliocene, so it can make it harder to identify things. The first one I assume might be crocodylian or maybe turtle, not sure. Those thick grooves make me think maybe crocodylian. The second seems like, from looking at the root base, a possible theropod tooth? I thought maybe claw of a turtle, but seeing that thick base makes me think otherwise. Lastly fou

Hello, I have a specimen of a mandible with teeth for your scrutinization. It was found some years ago in the Campanian St. Bartholomä-Formation of the Gosau-Group of Kainach, Eastern Alps, in Styria, Austria. I am little bit concerned about the bone texture and also the arrangement of the teeth. It seems it could be in urgent need for visiting a really skilled orthodondist. What do you think, does it really need some medical treatment? Many thanks for all your comments! Franz Bernhard

It seems that every time I post in the fossil ID lately, it's something my friends found when they were with me - brand new eyes are really good at avoiding the "routine" we get into when hunting, and they produce all sorts of crazy cool finds as a result. Here are some field photos of something I suspect is fish scales - I can ask her for better photos if needed. Ozan formation, mid-campanian of the cretaceous, Texas Here's a side angle I took so that the ridge is more evident: thoughts?

Hello forum members! With the new Coronavirus raging across the world, I thought it would be nice to start some kind of advent calendar, using my own Squalicorax collection. Everyday I will post one or multiple Squalicorax teeth from one location. Let's see what ends sooner, my collection or the virus outbreak. I will start with the oldest tooth from the Albian substage and end with the teeth from the uppermost substage; the Maastrichtian. The first one is the oldest and also one of the smallest teeth in my collection. Unfortunately it is so sma

Hello all During my fossil hunt yesterday, I found these two shark teeth right next to each other. I assume both are the same species, I just don't know which one. They were found in the region around Mons/Bergen in Belgium, where both Campanian and Maastrichtian seem to occur. I don't know exactly which layer these came out of, since I found them in a collapsed wall. Sharks seem to be quite rare here, so really happy with them. As found: The second tooth: Thanks all for your help.

During a recent trip back to W.M Browning Cretaceous Fossil Park in Northern Mississippi (Demopolis Formation, Late Campanian) I collected another mosasaur tooth. While incomplete the condition is still very nice. I am aware of the difficulties in identifying isolated mosasaur teeth but have been attempting it nevertheless. If nothing else I've learned more along the way. Two questions for this tooth. The first is the general question if anyone has an idea about the identification. The second pertains to what qualifies as serrations on mosasaur teeth. There are "crenulations" present on this t

Hello everyone! This is a partial mosasaur jaw with other associated bones i found in the Early-Mid Campanian Woodbury Formation of New Jersey over the summer. One of my best finds to date.

I have been too busy to get out fossil hunting when I want but there are a few recent times I've been able to get out. I wanted to try and post a small trip report about them. On October 31 I had the opportunity to visit the W.M. Browning Cretaceous Fossil Park in Prentiss County, Mississippi. Most people from the area are probably familiar with this old site but I'm a new resident to this part of the South so I wanted to give it a try. It's Late Campanian Demopolis Formation. It was a little cold and rainy but warm enough for someone used to North Dakota. Apparently th

Taxonomy from fossilworks.org. Woodward 1901, p. 66: “Head and trunk much laterally compressed, but elongated. Mouth terminal, the mandible with truncated symphysis and high coronoid region; a single series of small, conical marginal teeth; stouter and blunter teeth within the mouth, but apparently not on the parasphenoid. About 10 branchiostegal rays. Vertebral about 90 to 100 in total number, the centra short and deep, marked with delicate longitudinal ridges. Pelvic fins scarcely smaller than the pectorals, which are inserted high on the flank; dorsal fin extending for more than half

Taxonomy from gbif.org. The fish was originally described by Agassiz under the name Osmerus cordieri. Description of the genus by Woodward 1901, p.247 “Head small and trunk moderately elongated, the maximum depth at the insertion of the dorsal fin. Mandibular suspensorium much inclined backwards, and cleft of mouth large; jaws slender, and maxilla not expanded behind; teeth minute, numerous and sharply pointed. Gill-rakers large and slender. Vertebrae about 45 in number, half caudal and half abdominal; the centra at least as long as deep, longitudinally striated; ribs delicate. No fi

I've been quite busy lately but I managed to get out on October 30 and drove up to check out the W.M. Browning Cretaceous Fossil Park in northern Mississippi. Despite the high water levels I did pretty well and also found this small mosasaur tooth. I'm aware of the difficulty of identifying isolated mosasaur teeth but figured I'd post it anyway in case anyone experienced with mosasaurs or this area can narrow it down even to subfamily. Plioplatecarpinae? This comes from the Demopolis Formation which is late Campanian. CM scale

Last January 12, I found some Exogyra sp. oysters in a limestone Late Campanian / Early Maastrichtian strata (SE Pyrenees, Catalonia, Spain), who turned to show abundant beekite rings. I owe to @abyssunder my knowledge of this mineral phenomenon, which, in my area,occurs mainly over laminar-type shells like oysters' (It can occur on other fossils, though). Have you fossils with beekite rings ?

Atlantic Coastal Plain Amber (Bladen Fm., ~77-75 Ma)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
Select pieces of cretaceous (mid-Campanian) amber from North Carolina, weighing roughly 0.7-1.5g each; most pieces found from this locality only weigh under a couple grams, which is typical of most U.S. deposits. Along many portions of the Neuse river, south of Goldsboro, the embankments expose the various members of the Black Creek Group: the Bladen member overlies the older Tar Heel Fm., and underlies the younger Donoho Creek Fm. To date, amber has only been officially described to occur in the Bladen member, and is believed to be of araucarian and/or cupressaceous origin.© Kaegen Lau

cyclolites ellipticus Campanien Dordogne France Thanks Marguy for these great fossils ! -
I have found this claw from a site in Eastern North Carolina which has maastrictian and campanian material. Does anyone know if this is dinosaur ? Some dinosaur material has been found here in the past. Or is this crocodile or turtle maybe? It has the blood grooves on each side, unfortunately the tip is broken off. It is slightly hollow with an oval cavity. I tried to capture as much detail as I could with pictures. Thanks for your help.

Appalachia: Merchantville Fm (Santonian-Campanian) new Hadrosaurids and return of Dryptosauridae
AlexSciChannel posted a topic in Documents
A new paper by Chase Brownstein published today describes two new taxa from the Merchantville Formation of Delaware and New Jersey. A new tyrannosauroid of which metatarsal material was previously described here: https://doi.org/10.7717/peerj.4123 this time a new recovered vert was collected from the same locality likely belonging to the same individual. This thorough analysis of metatarsalian material has given the prescedent to return the tyrannosaur family known as Dryptosauridae which includes Dryptosaurus aquilunguis and the Merchantville taxon. Also described is a new H- 2 replies
