  1. Last week I stumbled upon a deposit that might be yielding a bit more. Several bone fragments, a vertebrae (I think), lots of boney plate material, and a small tarsal bone. I have collected this area for years an never found as much in one spot as I did last week. Going back with proper tools for looking further. Wish me luck.
  2. 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.
  3. researching obscure dinosaurs

    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?
  4. Identifying layers of sediment

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

    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 :-)
  6. Lavernock bone bed

    This is being sold as a bone bed from Lavernock, Wales. It is labelled as possibly dinosaur. It is rhaetic triassic. Could it be dinosaur?
  7. 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)

  20. Nothosaur tooth

    From the album Triassic vertebrate fossils

    A not so nice but big (3.2 cm long) Nothosaur tooth from a triassic "Bonebed" from a quarry in southern Germany (Baden-Württemberg). During the preparation the tooth broke in several pieces but I managed to glue them back... Some more pictures:
  21. Birgeria mougeoti

    A fish tooth (Birgeria mougeoti) from the Triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). Its about 0.6 cm long and relatively common. Another picture:
  22. Nothosaur vertebra

    From the album Triassic vertebrate fossils

    A 3.5 cm long Nothosaur vertebra from a triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). The prep work was kinda hard, because the stone is extremely hard and the fossil is very fragile. So I think it took about 3 hours. Here is a picture of the unprepped fossil: And finished: As you can see I decided to restore a bit, but nevertheless I am satisfied with the result
  23. On to the Dinos. As I mentioned in an earlier post, I found some helpful information here about the Triassic fossil material from Bull Canyon before we started collecting the fossils so I knew going in that some of the dinosaur stuff may not be dinosaur at all or at least it may not be the dinosaur that they are sold as. The fossils are educational so we will present them as we purchased them while noting the uncertainty in documenting our collection. We want to do what we do with the sharks and start our programs as far back in the evolutionary line as we can get. Bull Canyon gives us possible dinosaur fossils that represent very early dinosaurs. The kids will likely not know much about early dinosaurs so these fossils are important in giving us that bridge. We bought three very small, and inexpensive, "Coelophysis" teeth. One of them looks that it could be a dinosaur tooth while the other two are probably not. I found a great piece by Troodon here that outlined what to look for in Bull Canyon teeth and using his profile of what to look for from a dinosaur tooth from Bull Canyon, I contacted the dealer I bought them from. He is going to find us one that fits that profile so I feel good that we will have one or two Triassic Theropod teeth. If they are actually Coelophysis or not is not a concern. That is the species we are presenting to the kids because they are such a well known early dinosaur. The kids can learn more about them on their own and they may get really interested in early dinosaurs if we can connect them to one. It gives a an opportunity to touch on basic theropod biology and get into evolution. We also got a small and inexpensive "Prosauropod" tooth. I did know before buying it that no diagnostic prosauropod fossils had been found in Bull Canyon. I can accept that this one is unlikely to be prosauropod but we are still going to present it as one because the kids will really enjoy hearing about the forerunners of the very well known Long necks. I do not have all the science info set for this part of the presentation. I am still learning about early dinosaurs. I do not think we will be able to add much to this part of the dinosaur program. There does not seem to be a lot of fossil material available so i think this will have to be enough. Pic 1 our tiny collection of tiny Triassic "dinosaur" teeth.

  25. 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.
