I found this near the 476 turnpike where they tore up all the ground and exposed the New Brunswick Formation. This formation is triassic. I went to a dump site where the construction company took all the rock. Is this possibly some sort of trace fossil from a lizard or sphenodontid? (If you neer to see it better flip your phone or device upside down)

This is a 1.2 cm long Acrodus tooth with a nice structure ! Those are very common in some layers in the "Bonebed" in a quarry in southern Germany (Baden-Württemberg) but bigger ones are quite rare.- 1 comment

This is my biggest Nothosaurus tooth until now with a length of 2.5 cm ! Its from a quarry in southern Germany (Baden-Württemberg) from a "Bonebed" (Triassic). Some more pictures:- 3 comments

In a recent trip to the Candelaria Mining district of west central Nevada some rocks that suggest fossil forms where found. Is this a fossil? How big where coiled Nautiloids in the Ordivician? Is this more likely Permo-Triassic? I have more pics but the file size limit. Maybe another post later.

Need some help identifying layers of fossil sediment along a steep cliff side, having a hard time distinguishing time zones. Thank you!

I found this on the foreshore at Penarth beach (rocky) close to cliffs. I assumed it could be a trace fossil of some kind? Somebody on Reddit suggested perhaps Fusulinids, and they certainly resemble those from what I’ve seen, but it doesn’t look to tie in with the age of the rocks at the site.

I am currently spending a bit of time every day looking into dinosaurs that are off the beaten path. One of my goals with our education programs is to introduce kids to more obscure dinosaurs that they will not have heard of. We have a few fossils that accomplish that goal already in our program such as Thescelosaurus and Struthiomimus. Scientists and collectors know these dinosaurs but kids do not. They are that next level of knowledge beyond T-Rex, Trikes, Sauropods, etc. We are adding a Leptoceratops tooth for this reason. it is a weird little dino that the kids will not know but will be really interested in. Ceratosaurs are another that get that reaction too. They are overshadowed by the more well known large Theropods. We do this within the Dromoaeosaur family by busting out our Atrociraptor tooth. It is just different enough to really get their attention. I have been reading up on Alvarezsauridae lately and they are a really interesting group of dinosaurs. I doubt we will obtain any fossils but they may be worth mentioning without fossils which is not a common practice for us. I think the Troodontids fit this bill as I have yet to hear any kids mention them and I will be working on getting a Troodontid tooth here in the next few months. It is on the list for sure. I had a lot of fun getting ideas for non-dinosaurs to include in our programs so I thought it would be really fun and informative to get the opinions of the very sharp minded dinosaur collectors here. Keep in mind that our goal is to give fossil examples with the dinosaurs we discuss so do not get to crazy with species from China or South America lol Keep suggestions to North America, Africa, and Europe. I am not adverse to tracks and eggs either. What are some obscure or strange dinosaurs that we can look into to expand our programs?

Here's a hard one: This is a very nice temnospondyl skeleton (you can see the sclerotic rings!). It measures about 11cm long from snout to what is preserved of the tail. My question is: Can anyone tell me the genus/species and provenance of the fossil? I was told by the previous owner that it was possibly Platyrhinops from the Lower Triassic of Germany, but I have no idea. It looks like maybe a very well preserved Permian age Discosauriscus from the Czech Republic or some sort of temnospondyly from the Pfalz of Germany. I am happy to share more photos. Thanks for the help :-)

Our Shark Education Program- Cows, Crows, and Goblins
fossilsonwheels posted a topic in Member Collections
After the Hybodontids, our program starts to transition toward the modern sharks. We introduce lamniform sharks and the cow sharks. We will not be able to spend much time at all on the Cow and Crow Sharks. They only get a brief introduction and a look at the teeth. Squalicorax is an important species for us even though we do not spend a lot of time on it. The students in first few classes we do presentations for will be going home with Squalicorax teeth from Morocco. We would like to spend more time on the Cow sharks eventually but we only have one tooth to show them and we will have to edit content to free up space for them but I will work on that down the road. The primary focus in this section is Scapanorhynchus. The first shark art Carter did was a Goblin and we do give them a lot of time in the presentaton. They look cool and have been around for a long time. We present the kids with a nice assortment of teeth and some cool science. The teeth were important adaptations for catching fish and the snout had the ampullae of Lorenzini for sensing changes in the electro magnetic fields around them. We compare this to the modern hammerhead which we do not cover in the program but gives the kids a sense of how the adaptations of hammerheads work. We also talk about fin structure and being able to tell they were slow swimmers. The extend-o-matic jaw is another adaptation we cover with this species. I am happy with the fossil representations for now though I really want to add more Cow Shark fossils at some point and Anomotodon would also be a good addition. The fossils for the presentation.. Pic 1 Hexanchus andersoni from STH. I know H. andersoni should chronologically fit later but Cow Sharks fit here and this is the only one we have for now. Pic 2- Squalicorax pristodontus from Morocco. This is our largest Squalicorax tooth. The kids will get these teeth to take home so while we do not spend a lot of time on them, the teeth are very important to the program. Pic 3- Scapnorhynchus texanus and Scapanorhynchus puercoensis. Our nice little Goblin Shark display with some of our best teeth. Two of the texanus teeth are over 1.5 inches and the puercoenisis teeth are uncommon I believe and pretty super cool.

ID requested: Triassic Bull Canyon Formation microfossil teeth (Norian Age)
ziggycardon posted a topic in Fossil ID
Hi! I recently aqcuired quite a lot of "microfossils" to kick off my Triassic collection, as I personally find it one of the most interesting time periods and while I am aware possibly not all of them are ID'd correctly I just wanted to get some nice fossils from this time period regardless of their ID's. All the fossils I acquired are from the Bull Canyon Formation, Dockum Group, San Miguel County, New Mexico, USA (Norian age) But I myself am not very knowledgeable yet in this material as I just started my collection but I am aware that some if not most of the ID's on these fossils given by the seller might be wrong as everything I read about the Bull Canyon formation says that the formation isn't that well discribed yet. I tried to make the photo's as good as I could, but it wasn't always easy given their extremely small size, so I hope the quality is good enough to work with. So I am kinda hoping is someone here on the forum would like to give it a try to see if he/she could confirm or disprove given ID's. Thank you in advance! The first set of 2 teeth were listed as the Phytosaur "Pseudopalatus" teeth which after doing a bit of research is considered a junior synonym for "Machaeroprosopus" The next collection of 3 teeth were listed as the Pseudosuchian "Revueltosaurus" The next tooth was listed as a "Theropod indet" tooth, and I know there are at least 2 species of theropod present at Bull Canyon, a Coelophysid called Gojirasaurus and a herrerasaurid called Chindesaurus. But I am not even sure whether this tooth is dinosaurian or not. The next set of teeth were listed as "Arganodus" lungfish teeth And the final tooth was listed as a "Sphenodont" (Rhynchocephalia indet.) tooth with affinities to Clevosaurus (which is found in Nova Scotia, Great Britain and China).jpg.c21fd51aec9f6112713a83e42aadaa97.jpg)
