  1. My sweet Lariosaurus?

    Hello everyone! Here a Lariosaurus(?) found in a Quarry in Alcover - Montral (Tarragona) from mid Triassic in Catalunya. Most of the quarries are out of work and a pleasure to spend Sundays digging. The site is a lagrestatte, used since Romans period for construction. Possible to find shells, fishes, arthropods and, ia lucky case, something like this one. I am not sure of the fossil identification, as I based my knowledge on some works from XIX century (Villalta). As the head is missing I can only assume it is from the Nothosauridae family but not sure the species. As arms have fins and legs have fingers I suppose it is a Lariosaurus, but.. Can somebody help me to identify it? Thanks a lot in advance!
  2. Footprint maybe?

    Found this not far from the other footprints. This is sandstone. I can’t really tell for sure.
  3. The old Granton Quarry site, located in North Bergen, New Jersey was a working quarry that has produced fauna from the Upper Triassic Lockatong Formation part of the Newark Super Group. Underneath a basalt cap, in beds that are tilted, are shales and sandstones deposited in an ancient tropical lake bed. Biodiversity is far from rich. The most common vertebrate fossil found is Diplurus newarki, a small coelacanth, usually 2-4 inches in length. Other fossils include Estheria ovate, a clam-shaped shrimp-like crustacean. Rare remains of reptiles have also been found at the site. Development has claimed most of the quarry site, but an outcrop remains in an area that is unfortunately a repository for trash and graffiti and infested with poison ivy. Because of the poison ivy winter is the only time the site can be visited. I've been visiting the old Granton Quarry site once or twice a year since 2013. I've brought a number of TFF members to Granton, but Tim (fossildude19) has a been my companion for almost all of those trips since the first one. Last Sunday, the weather was mild and Tim and I accompanied by TFF members Dave (Shamalama) and Paul1719 visited once again. The site, always a difficult one to work, is becoming more challenging. The cliff is, I estimate 40-50 feet tall, but it is a less than one inch wide bed of black shale (called G-7) that is very fossiliferous. That bed is generally flush with or indented into the wall. All of the easily accessible G-7 has been already dug out. Where it is exposed and weathered it tends to splinter into fine shards obliterating any fossils that might have been present. Deeper in the wall it incredibly hard. Pulling out a decent size chunk to split is difficult to say the least. Finding a few already started cracks I was able penetrate deeper using my sledge and long chisel. Then I used my crowbar to wedge them out. In a full day of digging I was able to wedge out two chunks of G-7 , each several inches across. From these I got the majority of specimens I found. One piece appears to have two complete or nearly complete Diplurus which I sent to Ptychodus 04 in Texas to prep. In addition to fossils, Tim found a live red-backed salamander, our first amphibian siting of the spring. Here's Tim:
  4. Interesting coprolite

    Hi guys, I normally collect only bones but in the layers where I collect them, coprolites are also often abundant. But mostly they are not very well preserved so I don't take them with me. This one is the best one I found so far and I wonder if it might be possible to find out which animal "produced" it It comes from the so called "Grenzbonebed", which is a triassic layer between Muschelkalk and Keuper. Its approximately 4 cm long. It would be great if someone can help here. Maybe @GeschWhat? My personal guess would be that it comes from a fish (maybe shark)... Thanks and stay healthy!
  5. Triops longicaudatus?? ID request

    Good morning folks. I have a plate containing two of what I 'believe" to be Triops longicaudatus specimens. I purchased it from China years ago and it was listed as "tadpoles from China". My research leads me to the Triops species, am I correct? If not, please point me in the right direction. The largest specimen measures 9cm x 4.2cm. Help......
  6. Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to commonly observe the item of interest; paler orange indicates times in earth history to less commonly observe the item of interest. White indicates very little to no practical probability of observing the item of interest. Please keep in mind that the listed indicators are things like “conspicuous horn corals,” purposefully declining to address rare encounters with groups of low preservation potential, low recognizability, etc. Got additions/amendments, especially for the groups mentioned above? Toss them in the comments below! Thank you..... https://docs.google.com/spreadsheets/d/1tVm_u6v573V4NACrdebb_1OsBEAz60dS1m4pCTckgyA

  8. Lower Callovian, Bov Fm, NW Bulgaria

    Hello everybody! After a week of snow, saw sun for three days and decided its a good idea to visit a honey spot. Sadly, the sun was deceiving, the snow has not yet melted. Actually it was about 20-50cm. This location is very special to me because: i) Its 30mins from home, which means I can visit again and again. ii) According to the scientific researches I managed to gather, it has an extreme variety of fossils and exposed outcrops, dating from the WHOLE Mesozoic era. iii) Furthermore, all researches state that it bears excellently preserved fossils of ammonites, belemnites and brachipods. Of the last two, I do not have even purchased samples. PBDB has nothing published for this place. There are places around with some information and findings but it is not the perfect places. I managed to put together 5 different researches so I have narrowed down my possible locations. The last one, which actually gave away the location with coordinates is here: With a first glance I do not see much exposed outcrops, but the existance of a creek is a good sign to have caused erosion. Click here for the location through google earth. My other lead comes again from the same professor. The previous research was isotopic while this one studies only the distribution of ammonites and bivalves during the Toarcian in that specific section. Through this map, I conclude that following the small river you should see Aalenian to Callovian, on the small hill NNW of the river is the upper part of the Jurassic and the beginning of Cretaceous. East and following the course of that small river, you may be able to see exposures of Triassic. Last picture shows what I have put together and my possible places I will visit. I) The sections marked with yellow next to the main road cutting represent this description: It is an exposure of the Ozirovo Formation which is composed mainly of Fe-ooidal limestones and rare ferruginized marls, having a total thickness of 3.25 m. I will not check those places as I would prefer to avoid curious eyes and questions like what are you doing here. II) Marker with coordinates after Dr. Metodiev and his isotopic research on belemnites. On google Earth doesnt look promising, hope I am proven wrong. III) With light blue I depict the area which seems most interesting to me. IV) Orange triangle is possible location for Triassic exposure. V) Purple is the road I followed today. Line with car and dots on foot. I spotted some rocks, definately CaCO3. No sign of fossils. Almost everything was covered with snow. I will visit it again next week, weather permitting. Meanwhile, I would like to hear your comments concerning the locations I mark. What other spot looks good to check? Do I miss something? Findings, pictures and the rest will continue on the same topic of course. Thank you everyone for reading until here, sorry for the long post! ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Sources: GEOLOGICA BALCANICA, 36. 3—4, Sofia, Decemb. 2007, p. 91—96.

  9. I recently purchased a small lot of Bull Canyon Formation, New Mexico teeth, most of which were Phytosaurid. Then i noticed this tooth and how eerily similar it is too Pterosaur teeth from Morocco. From what i've read, there have been documented Eudimorphodon fossils collected from the Chinle Group, however i cannot find pictures for comparison. The closest teeth i can find from New Mexico are Preondactylus and Peteinosaurus teeth that have been put up for sale on multiple websites, though the information provided with them is unhelpful. I've included a photo of the "front", "back" and a side profile of the tooth. If clearer photos are needed to assist with identification, i can get some taken and uploaded.
  10. Triassic Shale Skull

    Red shale by flat run creek. Is it a skull? If so any help identifying appreciated.
  11. Coprolite verification

    Good morning folks. I purchased this box of coprolites many years ago under the description "Triassic carnivore fossil dinosaur coprolite, New Mexico". Did I do good or did I get taken?
  12. I'm not to sure if is the right part of the forum to be asking this but is anyone or would anyone know any experts/specialists that have a focus in Triassic Reptile/Amphibian Remains? Can even be a recomendation of an email address for a specific paleontologist I would be able to contact in regard to discussing a specimen directly and privately.
  13. This paper came out today. For those who saw my post of the palm leaf in both Alaska and the Smithsonian... this explains what I was doing in Fairbanks. I was up there for a total of five weeks stretched out over five winters. Yes, Winter in Fairbanks. I was hoping to see minus 40 degrees, but it never quite made it. I am "a fossil preparation specialist worked in two-week stints over the course of several years to get the fossil cleaned up and ready for study" https://news.uaf.edu/new-thalattosaur-species-discovered-in-southeast-alaska/?fbclid=IwAR0f-Lg4vDgE5MVuxP7wOL1V_CV3v142uy7Y9slvyNdH-xfE0t0AiZpp5Uw There is a paragraph about it Kirk Johnson and Ray Troll's latest book... "Cruising the Fossil Coastline"
  14. I will trade these fossils for one well preserved European goniatite or European triassic ammonite (specimen with 5 to 8 cm preferentially) because that kind of specimen is lack in my teaching collection. Note the Anorthopygus orbicularis is not a common species and, apart the incomplete test, has an exceptional detailed preservation, rarely seen. Best regards, Ricardo Traded
  15. Trip to the Triassic

    Last weekend I went to the south, to the area of Chrzanów - I have tried before twice to get to the Płaza quarry, but it is impossible during the week, as it is an operating facility, so I needed to visit it on the weekend The weather was beautiful - it felt almost like spring. Looking at the pictures you would not tell it's the middle of winter here:
  16. Footprints and tail drag

    Turned this approx 4 sq. ft. rock over today. Lots of footprints and a nice tail drag.
  17. Sauropterygia bones

    From the album Triassic vertebrate fossils

    A 13 cm long stone with three nothosaur vertebrae and another unidentified small bone piece from a triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). The verts are very small, especially the one beside the bone fragment. The bigger ones are about 2 cm long. Detailed pictures:
  18. Hello everyone! I found this keichousaurus listed on online. It appears quite legitimate. Could you please look at the photos provided and let me know whether you think it is a legitimate specimen? Many thanks.
  19. Unknown footprints

    Don’t know what this print is. Doesn’t look like the chirotherium. Found it today.
  20. Rock full of tiny prints

    Turned over this large rock this morning. Covered in small (1-2”) three toed footprints.
  21. Another rock of chirotherium

    A nice set of chirotherium.
  22. New chirotherium

    Finally some nice weather to do some digging. Couple more single prints. Got a crane to start moving the big slabs with multiple prints!
  23. Nothosaur tooth

    From the album Triassic vertebrate fossils

    A nicely preserved 3 cm long Nothosaur tooth from a triassic "Bonebed" from a quarry in southern Germany (Baden-Württemberg).
  24. Ichthyosaur Collection

    Hi Here’s another fossil I found over Christmas. These bones are pretty rare and are the articulated ischium and pubis from an ichthyosaur. No prep involved apart from cutting the block to size and applying a thin coat of varnish to increase the contrast between the bone and matrix. The fossil is from the Hettangian of Penarth. The block before:
  25. Hybodus fin spine

    From the album Triassic vertebrate fossils

    This is a 12 cm long Hybodus fin spine from a triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). Its until now my best preserved fin spine from there. Some more pictures:
