  1. Found this in same creek by DFW airport, Eagle Ford/Alluvium mix. So has basic shape of an ammonite but really thrown off by strange pattern, not typical wear and each side so different. Just don't know what to make of it.
  2. Greetings y'all. As many of you know I work at the Tate Geological Museum in Casper, Wyoming. As many of you don't know, we used to host a Spring Lecture Series every year for the people of Casper. This year we decided to start it up again, using the newly acquired skills of Virtual Gatherings. The theme this year is Cretaceous Dinosaurs. The talks are scheduled for the first Tuesday of March, April and May. Here is the link: https://www.caspercollege.edu/tate-geological-museum/events/lecture-series/ The Zoom link is on that Tate Museum web page. The tal

    Mosasaur or croc?

    Hi all, I recovered this split tooth from Big Brook park in Monmouth, NJ (late cretaceous). I've checked a couple websites that give information on Big Brook, and I can't conclude either way if it is mosasaur or croc (or similar to a croc). I included close-ups to show enamel, and held it to show the shape of the tooth towards its root. Thanks, Steve

    Two Medicine Hadrosaur vertebra ID

    Hi! I got this Hadrosaur caudal vert from the two medicine formation. in Pondera County. I was wondering what part of the tail this bone would have come from? the seller says it is likely a proximal vertebra, but couldn't give any details on its placement. Is there any possible way you can tell what part of the tail this fossil belonged to? assuming a grown individual of the species. If exact placement isn't possible, Ill settle for general region. The centrum of the Vert is 2.7 x 2.3. x 2.2" and the process is 7.6" long in a straightline including the anterior points

    Is this really it?

    Hello, I received this yesterday as a birthday gift - it was sold as an imprint of hadrosaur skin, Cretaceous, from Hell Creek. Do you think it really is hadrosaur skin?

    Cretaceous Micro Brachiopod

    This one is bugging me!!!! I know this is a brachiopod. I found it at the Reedy Point spoils along the C and D Canal in Delaware. It is 1cm in diameter. I have found two of them in the sand but none of them in the books. I have looked in Weller 1907, Wade 1926, Stephenson 1923, Richards 1958 and 64, and Lauginger 1988. I asked the folks at the repository for the Monmouth Amateur Paleontological Society. No dice. Look familiar to anyone?
  7. Hello, i have this little piece of fossil (2-3 cm) that i have no idea what it can be. Its from falaises des vaches noires in France which is Cretaceous/Jurassic area. There are mostly marine fossiles here. I was thinking fishbone fragment or plant? If anyone could help me i would really appreciate it.

    Mesaverde Formation Round 2

    I have been a little bored lately and missing micro matrix searches. It’s been awhile since I’ve gotten to enjoy hunting for tiny shark teeth. I got some more matrix from the Rollins Member of the Mesaverde Formation. My first time through that matrix produced one of my favorite finds, a 1mm Scyliorhinus tooth. This formation doesn’t provide much in the way of complete teeth but it is a fauna that was really quite diverse. The first search was with less matrix but I found enough to want to do it again. This time I have more matrix and in varying states. Some is broken down, some i

    Marine Fossil? Impression Fossil?

    Howdy everyone. :-) I think I've gotten a little better at identifying the Pleistocene fossils I've found (and figuring out when an ID is probably hopeless), but on the few things I've found that don't fall into that era, I'm still pretty lost. I found the rock below a while back in the Brazos River, in a sand and gravel matrix in the riverbed near Brookshire, Texas. It looks like a regular nondescript rock on its rounded face (top left), but on the flatter face (the other three pictures), it looks like it was cracked open at some point and revealed somet

    Boletechinus Sea Urchin

    This specimen comes from the 1980 dredge spoils of the C and D Canal. The type specimen for this species comes from the Navesink Formation exposure of the same canal, not far away. Known by locals, it was not actually described until 1986. Although not the most common of species at this locality, and almost unknown outside of Delaware, these miniscule urchins were nonetheless plentiful at the Reedy Point spoils. Recent excavation for barrow removed most of the sand where my specimen was found.

    Cretaceous sea

    Hello all, One of the many drawings/art works of me. Black pencil and edited with pc. This artwork comes perhaps in a book that will be published in July/August 2021. The Cretaceous sea (Kreidemeer) of Europe (late late Campanian and/or early Maastrichtian, 73-69/73-68 mya). Kind regards and happy fossil hunting! Ruben

    Sabre-Toothed Herring Tooth

    Vertebrate material of any kind is extremely rare at this locality. However, this is the most common vertebrate represented at Reedy Point. Found while sifting through micro matrix collected from an especially prolific, recently exposed spot that will soon be removed by bulldozers.
  14. Belemnites have been my core interest for decades, starting as an 8 year old kid when I saw and bought the pointy end of a large Cylindroteuthis in a curio shop (I still have it ). This led eventually to being able to research some Lower Jurassic ones for my Ph.D at university. I pursued another career after that (musical instrument repair and restoration) but palaeontology has remained a fairly fanatical interest ever since. Most of my early collection (including nearly all the research stuff) has been lost for various reasons but I've been able to replace much of it and added many new

    Glycymeris Clam Internal Mold

    Glycymeris clams have ridges along the inside edge of the valves that extend past the cardinal area. Internal molds tend to include these teeth, making them very distinctive. As of the time this was posted, this was the only member of the genus listed in the Paleobio Database for the Cretaceous period and it is only listed as being found in NJ. However, Stuart Weller (1907) and Horace G Richards (1958) not only include them in the C and D Canal zone, but identify three different species for the region. This one is the most common and the only one THEY found outside of NJ.

    Russian Sand Tigers

    I purchased some shark teeth recently, all or most of which appear to be sand tigers, from Russia and am hoping some folks on here might be able to help me identify them. The information from the seller, who is in Russia but didn't collect these himself, is that these are Cretaceous teeth found in chalk deposits on the banks of the Don River, near Kalach-on-Don, Volgograd region, Russia. He doesn't have any more info or know the exact geologic layer. I haven't been able to find much information from searching online, but using the app Rockd, it does appear that the geology in the a
  17. It's propably real and it has 10-15% repair. I don't know which species it belongs to (maybe Deinonychus or Dromaeosaur). What do you think?

    Marine reptiles of Madagascar

    Hi all, I recently became aware that Madagascar appears to have a fully developed and interesting Mesozoic marine reptile record, yet am not particularly able to find any information on them. The only article I have come across is Bardet and Termier, 1990, "Première description de restes de Plésiosaure provenant de Madagascar (gisement de Berere, Campanien)". However, I've been unable to track this article down. As such, I was wondering whether anybody on TFF might have any information on them. Basically, I'm starting from scratch, so would be very interested in the clades of

    Gasatropod

    As battered as this is, it is an unusually well-preserved specimen for this locality. Although there are brachiopods and bivalves that preserved as calcium carbonate at this locatlity, most gastropods in the Cretaceous of Delaware are either steinkerns or are preserved as battered phosphate with phosphate in-fill. Gouging appears to have occurred after fossilization since the matrix does not completely fill the gouges. Most shell predation at Reedy Point came from clionia sponges and boring clams. This resembles neither. This was found in loose sand from dredge spoils.

    Limburg (NL) fossils

    Hello all, Some photo's of my recent fossil hunting trips in the Netherlands (Limburg). All fossils are 73-66 and/or 73-69 million years old (late late Campanian, early Maastrichtien). Mainly belemnites (belemnitella and belemnella sp.), 3 sea urchin genus Echinocorys sp. (my girlfriends top find), one horse tooth (Equus sp.) a pipe and a bone (don't know species). Also on the first photo one trace fossil (ghost shrimp/crab) and one belemnite with holes. Kind regards, Fossilsforever
  21. I'll be honest, I've put off writing this trip report for far too long. Between work, school and general procrastination I have delayed this post for over 7 months. Perhaps there's a silver lining to me writing this in the middle of winter, it could act as a nice break from the grey & cold conditions many of us are facing this season. Hopefully you all enjoy a dose of warmth from a trip which I enjoyed greatly. Ok ready? Let's go. My morning started around 4:30, ungodly hours for me generally, but I woke up excited for what lay ahead. Less than a half hour later we were on our w

    Interesting Hell Creek Vertebra

    Hi everyone, I found this little, mostly complete vertebra in the Hell Creek formation of South Dakota in 2019. I don't really know what to make of it as it's very porous, and amphiplatyan (flat on both sides), although I'm not sure how much of that could be attributable to wear. I believe it's safe to cross of squamate (due to lack of concavity) and champsosaur (overall shape) off the list. While most of the crocodilian verebrae I have found in the hell creek have have a convex and concave end, I am aware that some can be found that are flat sided. The porosity of the bone makes me hopeful th

    Cretaceous Macro Fossil?

    This was found in the Turonian aged marine deposits of the Ladd Formation of Orange County, California. The size is .5 cm along the longest axis. Any ideas as to what this may be?

    Burmite Amber Insect Id help

    Hi everyone! Can anyone help me id some small insects in amber? They're all from Myanmar and about 99 million years old. They're pretty small, mostly about 2 millimeters or less. I took the best photos I could, any help narrowing down what type of insect (or possibly arachnid) is greatly appreciated.
