  2. Hey everyone! Im currently in Peniche, Portugal and I’ve been doing a little research and found that the Lourinhã formation is nearby. I went to the museum today in Lourinha town and saw some of the amazing finds that’s have come out of this formation! Can anyone recommend the best beaches to go to to fossil hunt? Anything specific I should be looking out for? Basically any advice would be amazing! Thanks

  4. 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.
  5. Hello, I almost die, when I was extracting this ammonite from wall of abandoned limestone quarry. So, that's my very first stone preparation, of 200 mm (7,8") ammonite (Perisphinctes), which I found near my hometown - Kraków, Poland. OK, I know, it's not so big, but the largest I have ever found. As You can see I got carried away, so it's half natural specimen, and half carving. Preparation I done with Dremel Engraver and some chisels I made from old files. I enjoyed it well

  7. Can anybody narrow down the genus here?

    Hey guys. I’ve got this bivalve that needs a labeling. I collected it from the Jurassic age Twin Creeks Formation on the east side of Salt Lake City. It has some shell material left but most of it is an internal mold.
  8. I’m a complete beginner so please forgive my ignorance. I found this on my second time deliberately looking for fossils. Honestly, I’ve no idea if it’s a fossil. I did find some other interesting things too but nothing like this. I’ve researched Penarth and it’s suggested that the formation is early Blue Lias? Or Lias Group and dates to Jurassic period. This was found towards the bottom of a cliff and I do not believe it’s been submerged by the sea. Thanks in advance for any pointers, Nathan

  11. Ichthyosaur Paddle

    Hello, this is my first post Just wanted to share my most recent find from the Jurassic coast of Charmouth, Dorset UK. I found this pebble with what appeared to be bone, had it prepped and it has turned into an ichthyosaur paddle with ribs/gastralia and a couple ammonites! Best regards, Kam

    Need some help identifying this tooth I found a big brook, I THINK it might be a croc but not sure. Maybe plesiosaur??
  15. 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?
  16. 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!
  17. Coprolite or pseudofossil ?

    Hi everyone, This is just another piece of something that I cannot identify, found at Yaxley, Cambridgeshire, UK, three days ago. My first guess is a cropolite fossil but I'm more convinced that this is just a piece of random rock. Yaxely Lake is very rich in Jurassic fossils buried in the Oxford Clay found there. I managed to find a lot of belemnites and ammonites but this isn't one of them. Any help you could offer would be greatly appreciated. Thanks, Bong
  18. Belemnite

    Hi everyone, Attached are pictures of three small fragments of belemnites I found three days ago in Yaxley, Cambridgeshire, UK. In the first picture, two of the belemnites are what I usually find in the lake but one of them looks significantly different. It looks like it is coated in thick white stuff (which I cant identify) which almost makes me believe this may not even be a belemnite fossil. Can anybody tell me what this is please? Is this even belemnite? Thanks, Bong

  20. TFF friends, How are you? It's been a while i post here although i still read almost daily posts on the forum. Last month on the 30 and the 31th, i had the opportunity to make a 2 days field trip to the yamaguchi prefecture with the association of the Goshoura Cretaceous Museum's friends. We spend 2 days there discovering the local geology and history with paleontologists friends. Let me share with you this experience. First day. We left kumamoto at 7 in the morning and drove for about 3 hous to our first destination called Mine. Around the city of Mine and particularly on the northern part of the city can be found the toyoura formation. It is a clastic sediment marine formation that formed during the sinemurian-bathonian period. This formation formed the same way Holzmaden formed and a lot of very well preserved marine organisms such as bivalves, ammonites, belemnites and plants can be found. We first explored a small river without much success. While everybody found plant fragments, i found 2 nice belemnites. I read that belemnites were pretty rare and that only one specie was described from this formation so i believe they are Acrocoelites mantanii from the megateuthidinae sub-familly. We found only few fossils there but it was a great occasion to enjoy our meal under a japanese cherry tree, symbol of the japanese spring. We then followed the stream until the main river where we search the river bed for ammonites. We found some nice specimens (Dactylioceras, Cleviceras and Protogrammoceras) and some plants material (i love the coloration) but we had to leave quickly the river bed as the water level rose-up in a blink of an eye. Weather was good but where we were but you never know what happen upstream. One cannot be too careful. We leaved the field and were about to drive to the Hotaru Museum when somebody told us by inadvertancy that the older part of the parking lot was filled with fossiliferous limestone from the Akiyoshidai locality. We didn't have to think twice and went through all the gravel in hope to find carboniferous fusulinas, brachiopods, and corals. We spend 30 minutes there and were about to leave when we noticed tortoise bones were here and there, lying on the floor. Do i have to explain you what followed? TREASURE HUNT! We finally left the place for the hotaru museum. It is a small museum dedicated to the fireflies but part of the exhibit contained also fossils. Here some pictures. After the museum, we checked-in at the hotel and had a rests with well-deserved beer, some card trick and a lot of fossils conversations. It is being late here so i will post the next post tomorrow. I hope you have enjoyed this one. David.
  21. Help needed to ID vertebrae

    Hello everyone, I was wondering what these vertebrae from a Jurassic formation in France (Vimereux) could be from. I was thinking plesiosaur because of the shape but I’m not sure. They are all around 10cm in diameter and these are the only pictures I have. Thank you for any input. Regards
  22. Help identifyng these ammonite species

    Hi, I found these ammonite specimens in the Oxfordian Ammonitico Rosso facies from the Baleriac Islands, Spain. I know that the preservation state is quite poor but I would like to get some help identifyng the genus and species. I am not familiar with ammonite description but here you have a very basic description of what I see: Specimen 1: No ribs, oxycone/discocone, involut, carinate? Specimen 2 (Taramelliceras sp?): two pair of ribs (primary and secondary), oxycone/discocone, involut Specimen 3: No ribs, discocone, carinate? Specimen 1
  23. Hey everyone, I purchased this fossil that was labeled as a Marshosaurus bicentesimus jaw from the Morrison formation in Wyoming. I wanted to get other opinions on it? Is there enough here to say it's a Marshosaurus jaw? Thanks everyone.
