Hi from Washington state! I was wanting to talk to people about paleontology and then realized that were probably many paleo forums. Guess I'm here now haha. I tend to focus on Mesozoic life but sometimes I go off the deep end and spend a few weeks obsessed with the Paleozoic or Cenozoic. I have some fossils but no vertebrate fossils yet: I have a chunk and a log of petrified wood, a snail shell, a leaf, and some shark parts. Looking forward to going on some hunts one day but WA is more for mammal fossils. I'm looking to go into paleontology at the University of Washington and I'm excited to finally be at school for my passion. Looking forward to geeking out over bones with you!

I've always loved living fossils, especially the fish. They are relics of an age long lost, offering us a glimpse of an incredible prehistoric world. Some are enigmas that survived countless extinction events since the Devonian. Others are majestic predators that swam alongside the dinosaurs. Let me present my collection of living fossil fishes from the Mesozoic and before. I will begin with one of the most famous of all - the coelacanth Coelacanth Species: Whiteia woodwardi Age: 252.3 - 251.3 mya | early Triassic Formation: Diego Basin; Middle Sakamena Formation Locality: Ambilobe, Madagascar First appearance: Eoachtinistia foreyi was found 360 million years ago in Australia Paddlefish Species: Protopsephurus liui Age: 125.5 - 112.5 mya | early Cretaceous Formation: Yixian Formation Locality: Lingyuan City, Liaoning First appearance: This is the oldest known species Sturgeon Species: Peipiaosteus fengningensis Age: 125.5 - 120 mya | early Cretaceous Formation: Jehol Biota Locality: Chifeng, Nei Mongol First appearance: Multiple species e.g. Yanosteus longidorsalis found since 125 million years ago in China Pipefish Species: Hipposygnathus sp. Age: 28.1 - 13.8 mya | Oliogocene - Miocene Formation: Monterey Formation Locality: Santa Ynez Valley, California, USA First appearance: Solenostomidae species were found 55.8 million years ago in Italy Note: Although most of this collection only includes fishes that existed since the Mesozoic or later, I made an exception for the pipefish as their order, syngnathiform, existed since the late Cretaceous

I was recently reorganizing my fossil collection and thought I would share some pieces I collected during Paleontology field trips in undergrad at Alabama. I'm glad I took thorough notes at the time! The demopolis chalk is a popular formation for finding Exogyra/ostrea/pycnodonte shells and shark teeth. We visited a site in Tupelo, MS many times for surface collecting. Some of the cool pieces I found were many fragments of a mosasaur jaw (top pic, top 2 slots), a Squalicorax kaupi tooth, a scyliorhinus(?) tooth, bony fish vertebrae, and bony fish teeth. I was told the dark fossils at the right of the third picture might be ray plates, but I'm not sure. Turritella in pic 1 are from a different formation.

Majungasaurus is the only abelisaurid from the cretaceous of Madagascar which has led to this identification. Appears to have been possibly added to the block of matrix.

I have a couple riker boxes of a few dinosaur teeth. Nothing super high quality; I enjoy a variety of teeth and was on a budget so I never looked for the highest quality of teeth to buy. I'm happy with a nice representative sample of the animal. I've moved away from buying many specimens now as I'd rather go out and find my own at some point, but I bought these years ago and I'm very happy with the diversity they represent. Plus as I teach geology, they are great teaching specimens for the kids to. First up is my collection of Cretaceous North American teeth from Hell Creek, Lance, and Judith River Formations. Most are dinosaurs, though there are a couple other fauna represented here to. Probably one of my favorite teeth from this box is the acid etched raptor tooth. Though I do really like the JR tyrannosaur tooth as well (I watched that one sell for more than I could hope to purchase, but it was returned as it splintered during shipping. So I bought it as a short prep project for cheap. I never filled in the cracks as I prefer most things unrestored).

Hello all, I was waiting a while to show my ever growing collection until I finally got this new shelf. I wanted to paint it to look similar to my other shelf, install these neat colour changing lights, organize things and move everything...then take photos! I had stored everything in my bedroom for a while but now everything is front & center for visitors. As has has been made obvious by my many ID posts and couple threads in the, “fossil hunting trips” section, I live in a fossil rich area have access to much land to collect from frequently, so I will use this thread for updates with future finds. I’m very proud to say that much of my collection, mostly the dinosaur stuff, has been found by me rather than been bought, though there is a lot of money invested here. If you would like more or better pictures, info or would like to help me ID anything in this collection that I’m unsure about (I’m severely lacking in physical labels at the moment) don’t hesitate to ask.

Hi all, I'm recently retired and I live in NW Wyoming and was wondering if anyone could shed some light on these specimens? Im particularly interested in the big rock/fossil? at the top of the picture. I found all of these on the surface in a sandstone, drab mudstone formation. Possibly Eocene, Paleocene time frame based on some quick geologic research. Looks like a foot to me but I suppose it could be about anything. The other items were found in the same area with the larger one. The area would have once been the near the edge or boundary of Lake Gosiute an/or the inland seaway I think. I have enjoyed reading some of the posts, seems like a good forum! Thanks, WyoProspector

Hello everyone! I'm currently in the London, UK area (though I repeatedly travel back and forth between Europe and Asia) and decided to join the forums because I'm hoping to start a PhD in Paleontology relatively soon. I attended the Paleontology Associations virtual meet up early this year and really enjoyed it, and after it finished really missed having less formal interactions with people who are also interested in fossils. So, I thought it would be great to be able to see so many peoples collections and specimens and so I decided to join. I'm mostly interested in macrofossils from the Paleozoic-Mesozoic time frame (though Terror birds will always hold a special place in my heart as well!). In my BSc I studied in depth Ammonites from the lower lias formation in the South of England and in my MSc I studied Sauropodomorph and Ornithischian dinosaurs. My current self-collected collection consists of several species of Ammonites (from Dorset in the lower lias), a sample of pipe rock (from Scotland) and several Gryphaea fossils (from several locations across Whales). I've also been lucky enough to purchase/be gifted several other fossils including Spinosaurus teeth, Eggshell fragments, fossiled Amber, a Hadrosaur toe bone and a Ceratopsian tooth. I look forward to chatting with you all in the future

Hello everyone, My name is Alexander and I'm originally from the Netherlands, although, for family reasons, I currently live close to the German border in the Alsace in France. I've studied to become an archaeologist and, as such, have some academic understanding of various fields that apply to palaeontology (e.g. geology, anatomy, taphonomy, ecology, etc.), even though I currently work as a computer programmer. However, I've had an interesting in dinosaurs and fossils ever since I was a child and fondly remember my father taking me on many a fossiling trip. After completion of my studies I rekindled this interest, which has since become focussed on marine reptiles of the Mesozoic, especially the big ones such as ichthyosaurs, plesiosaurs and mosasaurs. My collection consists both of purchases, as well as pieces found and prepped myself. With respect to the latter, our current location is ideal to visit all the great (world-reknowned) museums and collection sites in southern Germany and Switzerland. Finally, I now hope to pass on this enthusiasm to our son, who at his early age already has a great fascination with dinosaurs and some basic knowledge of comparative anatomy. I look forward to joining your discussions! Alexander.

Dear TFF-members, Can anyone help me identify the fossils in the photographs below? I have trouble identifying the concentric patterns that are visible on these (apparently hollow?) shell-like fragments. They were found in the Pyrenees, Spain. The formation in which they were found is Mesozoic in age, most likely Jurassic. Note these are outcrop photographs, so I cannot make additional images to aid identification, unfortunately. Thanks for any feedback you may be able to provide. Kind regards, Tim

Ok, I just came across articles about soft tissue remains, apparently including some form of degraded blood, in a mosasaur. That of course, brings up the T-Rex soft tissue found, to me. I seem to understand what I keep reading, but I can’t help it, again I find myself thinking...Really? C’mon, REALLY??? Am I just misinterpreting the whole thing, or is there actually real, true, gen-u-ine unfossilized/in mineralized, preserved soft tissues and blood remains in these 70ish million year old “fully” umineralized animals? ...............HOW?????????????? How, when the rest of the animal, soft AND hard tissue has dissolved away so long ago, can any soft tissue remain? How do only small areas of the tissue remain? If conditions are so, that areas of soft tissue/blood residue remain, how do just small patches remain, but the parts immediately surrounding the patches have long since dissolved away? Conditions inside an intact bone, or intact stomach cavity, should be stable, shouldnt they? Not different from one centimeter to the next, especially so different that one spot dissolved dozens of millions of years ago, and the spot touching that one is still just sitting there, relatively preserved?

Hello, everyone, I’m newly retired after 39 years of teaching. Over the years, I have collected, by purchase, to use as demonstration pieces in the classroom a wide collection ranging from Archean microbial mat cross-sections through time to Holocene cave bear vertebrae. My collection is very diverse through time, if limited in depth. I have a nice collection of Silurian-Devonian trilobites, some nice Devonian-Permian plant material, and a range of Holocene mammal bones; vertebrae and mandibles. ... I taught a variety of upper level secondary courses over the years. As Science Dept. Chair in an independent school, I oversaw curriculum (shorthand for “I got to teach what I loved) For many years I taught an Natural History course to seniors looking at the evolution of the Universe. First term Cosmology-Planetary Science; Second term Evolution of Life. A dream job. Now, I’m trying to complete a more formal indexing of my collection (which includes MANY casts as well). Nice to find you folks. Probably will be an infrequent visitor. Glenn

Today, instead of bemoaning the paucity of marine cretaceous rocks in my state, I reframed the situation as follows: "In the Cretaceous, most of Missouri was not ocean but land, with lots of exposed limestone that dinosaurs were likely walking around on." This led me to the following question: Do we have no fossil examples of dinosaurs that fell in sinkholes / caves / paleokarst and were preserved there, perhaps discovered during quarrying of the limestone? We definitely have such examples for fossil mammals, reptiles, etc., including Pleistocene (Ocala), Pliocene (Pipe Creek Jr.), and Miocene (Gray Fossil Site)... So why not earlier? Why not dinosaurs? Surely there were paleokarst processes in action during dinosaur times. As possibly useful information, there was definitely regional hydrothermal activity here in the Mesozoic, based on the Jurassic emplacement age of southern Illinois fluorite.

Hello everyone, I have decided a while ago that I would focus on collecting Paleozoic material, because of this there are quite a few fossils I have that I purchased a long time ago and do not have an interest in keeping, these guys are not that special and I am not looking for much of anyone even does want to trade with me, but I do prefer Paleozoic material. I will post what I have here. 1.Lebanese shrimp fossil Cretaceous GONE/TRADED 2. Geocoma carinata I believe from the Solnhofen 3. Chunkosaurus 4.some cretaceous teeth, spinosaurus, Squalicorax, scapanorynchus, enchodus 5. Some gastropods 6.otodus obliquus Morocco eocene

Help request! Seeking diagram of scleractinian architecture through time
pefty posted a topic in General Fossil Discussion
I recently saw a wonderful diagram showing the fossil ranges of various scleractinian coral architectures, or at least the ranges of genera typical of those architectures. But now I can't seems to find it again... The diagram included images of the various coral growth forms and was simpler than but otherwise similar to this: If anyone knows where I might have seen such a diagram, please post the url here -- thanks! -
So, apparently I started an account on this site back in 2015 but never posted anything. Not sure why? I guess I was in college and working and didn't have time to post. Anyway. I'm here and definitely want to start posting about my own collection and whatnot. I am still and always have been into fossils and really anything science. Biology and comparative anatomy was my first love. I do have some questions about some of my fossils and want to share my enthusiasm for paleontology. Thanks

Hi I was just at my aunts house and in her house I found a ammonite I asked her where it was from and she said she got it in Cuba which made me wonder what creatures lived in Cuba in the Mesozoic I found out In the Jurassic there where Pliesiosaurs, Ichthyosaurs and ammonites and lots of pterosaurs also there has been some dinosaurs too which surprised me because I thought Cuba was under water there’s a few remains of sauropods a Camarasaur and a Diplodocus like sauropod some more fragmented Sauropod bones and some bones of a unknown Saurischian also some unknown reptile bones have been found too I hope this helps with the Mesozoic creatures of Cuba this is my first informational post Thanks!!

Greeetings from Australia. I am a new member and retired Geologist. I did my graduate and postgraduate theses on Mezozoic faunas of New Zealand and Australia, so hopefully I can help any of you seeking IDs of fossils from these countries. My main interest is in brachiopods, the pic is from my collection : The large brachiopod is Mentzeliopsis spinosa and small ones Spiriferina (Rastelligera) sp. These are both from the Mid Triassic of the Hokonui Hills in New Zealand

Hey Everyone - I hope someone can provide some insight and help me identify this fossil. I would really appreciate it! I found this strange looking tooth (at least I think it is) a few years ago in San Antonio, Texas. It feels and looks like a rock as far as texture goes but it's shaped very similar to an animal tooth. I've attached photos for reference and labeled each one: Front Back Side Front Height - 5 inches (12.7 centimeters) Front Width - 4.5 inches (11.43 centimeters) I've also attached a Geology Map of Texas which outlines where rocks of various geologic ages are visible on the surface of Texas today. On the map, I circled in yellow the location of where San Antonio, Texas is for reference. Hopefully it can provide more insight for you. I'm not even close to a geology expert but limestone is very prominent in San Antonio. The city is also home to The Edwards Aquifer which may or may not be useful. I'd be happy to answer any questions and I can also take additional pictures if needed. Looking forward to hearing back from you all!

I found this near a river in La Matea (Jaen, Spain) the zone is predominantly mesozoic and the rock is limestone. I'm not sure if it's a fossil or some kind of formation. I have two similar specimen, is like a cylinder that goes from one side to the other of the rock, in one of the images I've partially removed some of the rock. Thank you.

Found today on the English Yorkshire Coast ( Runswick bay). At first i thought it was maybe layers of a type of fossilised plant but I cant find anything to match the markings on this. Completely baffled by it. Looks very cool though. ID help, please?
