Ozan Oddballs. Regular Urchin Fragment and Fish Jaw Fragment?
EPIKLULSXDDDDD posted a topic in Fossil ID
Took a trip today to one of my new Ozan spots that is rapidly becoming a favorite, despite the headache it is to reach. Although the finds are few and far between, I've always come out with something I haven't seen before. It's definitely been testing my ID skills. I didn't come out with too many things, but I've got a couple I would like to get some informed opinions on. First up is a regular urchin. I've found a few fragments of regular echinoids washed out within a small stretch of creek. Though this is the third I've seen, its the first of this appearance and first to safely ma- 7 replies

Hello all, This weekend another fossil hunt in Cretaceous sediments in the Netherlands (late late Campanian, early Maastrichtian, around 72-66 mya (whole late Maastrichtian) and/or (more specific) 70.8-67/70.8-68 mya). The wetter was good, a bit warm and even sometimes humid. Found some typical Cretaceous fossils. Mainly Belemnites from the species Belemnitella sp. and Belemnella (pachybelemnella) sp. Perhaps some B. (pachybelemnella) obtusa (Schulz, 1979) and one fragment of a sea urchin (Echinocorys sp.). Compared to American sites (for example New Jersey), a re

The Judith River Formation - Tooth ID, Faunal List & Localities
Troodon posted a topic in Questions & Answers
More and more dinosaur material is becoming available from the Judith River Formation. I see lots of misidentified material and some with questionable localities that might fit other deposits. I would like to summarize what I believe is currently known and published. If you see any omissions or errors, please let me know. Not a lot of good maps out there to show the formation but here are two. In general, the exposures are in North Central Montana. Horner describes the formation on the western end is near the east end of the Sweetgrass Hills (very thick about 152 meters) and -
a nice find of Squalicorax with verts from the german campanian
rocket posted a topic in Fossil News
Year ago two friends of mine found some nice teeth and vertebraes from Squalicorax. As they were found close together - what is very unusual - we decided to write a small paper about it. We came to the solution that the verts and teeth belong to the skull-region of the shark. Finds like this are very rare, not many published till now. Journal was "APH" (www.ap-h.de), founded in Hannover. A nice Paper (now existing 50 Years!), 4 issues a year full of papers about northern germany fossils and more 49-61 (Raquet).pdf- 2 replies

A few months ago I had the opportunity to collect a bunch of matrix from the Cretaceous aged (Campanian) Ozan Formation of North Texas in the "red beds". The larger fraction is rich in sharks teeth and other small macro fauna. After breaking down the matrix, I have put it through a number of sieves to facilitate picking and sorting. I have available lots of very fine matrix that made it through my 60 mesh sieve (so it is all smaller than 250 microns or ~0.25 mm). In this fraction I see lots of forams, some ostracods, and some other very small fossils. I am not really equipped to pick and

Belemnites are common in the upper cretaceous of NW-Germany. One of the nicest one is the upper campanian Belemnitella mucronata. This Belemnit got´s his name "mucronata" from "mucros", the tip at the top. Size is around 8 cm, Hannover -

Hello. Needing help to ID this strange fossil. Found in a quarry i Scania, southern Sweden. Lowermost lower campanian. Sandy biocalcarenites. Nearshore enviroment. The quarry have produced a number of rare, still unidentified fossils both marine and terrestrial. Findings of mosasaurs, marine crocodylomorphs, aquatic birds, flying reptiles, bony fishes, sharks and also neaceratopsian dinosaurs have been made in the quarry. I have sent pictures of this fossil to a local expert at Lunds University but it´s still unidentified. The brown bone seems to end

A field day with blueberries, some mushrooms and - fossils!
FranzBernhard posted a topic in Fossil Hunting Trips
I would like to share a typical "day off & out" during summer. During summer, I don´t do serious prospecting. Too hot, too green, too much distraction, like blueberries and mushrooms. So, last Sunday (07/03/2022), I mainly explored an area for "fruits" and visited two fossil sites discovered in October 2021. It was hiking-only, no driving between the various "stops". I found lots of blueberries (not fully ripe yet at 900 m asl), but it was much too dry for mushrooms. Nevertheless, I found a few places with a few Cantharellus cibarius: Some of them were even growing on extre- 9 replies

Found this bone of what I think is a jaw from a fish. Åsen locality Scania Sweden. Upper lower Campanian. Nearshore/deltaic enviroment. Greensand. Bone is 6 cm long and has a row of small "sockets" for teeth? Fish teeth found on the location is Enchodus, Protosphyraena, Pachyrhizodus... other finds include Tylosaurus, Clidastes, sharks, rays, turtles and chimaerids. Happy for any help on ID.

Fossil snails of the genus Trochactaeon from Kainach near Voitsberg, Styria, Austria (Gosau-Group of Kainach, upper Cretaceous) - Summary of this years prospection Introduction Snails of the extinct genus Trochactaeon (formerly part of the genus Actaeonella) are among the most familiar fossils of the upper Cretaceous Gosau-Group of the Austrian Alps. The rather large size of some species (>10 cm), their intriguing spiral pattern in transverse sections and plenty supply, based on many mass occurrence, make them particularly popular. Some well known occurrences in Austria, di

Identifying Theropod Teeth from the Two Med Formation
Troodon posted a topic in General Fossil Discussion
Identification of theropod teeth from the 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 have been made,- 6 replies

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. Sharks from the Late Cretace

From the album: Cretaceous Fossils of North America
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.
