Hello, these tiny fossils were difficult to photograph, I had to improvise by sellotaping a magnifier to the camera lens, as I do not have anything that can do the equivalent where I am now. I was wondering if one of them is possibly a bit of crinoid? The circular bit seemed to remind me of modern bone. Sorry they are muddy, I'd probably break them if I tried to wash them. Scale is in centimetres, and they were found in Northamptonshire, UK, which is Jurassic. Thanks.

This is an un-associated surface find from Brushy Basin so no context to draw on. No discernible internal structure when looking at the fractured end. Obvious symmetry and taper to a flat point. I have not found anything seed-like on the internet that is this large or shaped quite like this. So I am excited to hear back from the forum. I am new to the Fossil Forum and look forward to sharing in the bigger brain of paleontology.

I find the ribbing of this shell peculiar. Do you recognize this taxon? Oxfordian of Poland. Associated finds include: sponges, brachiopods & bivalves.
-
What do you think it is? The definition I got on the local forum is "conditionally classified as Plegiocidaris" Guides/handbooks on Moscow Mezozoic (unfortunately mostly outdated) list 5 genera: Echinobrissus, Rhabdocidaris, Acrocidaris, Holectypus and Cidaris. For this and neighboring stratigraphic zones Echinobrissus and Rhabdocidaris only, mainly the latter. Both are defined by spines, sometimes isolated plates

Hello everyone. I found this sticking out of a mudflat on the River Humber Estuary, UK. It seems to be a fossilised bone of something but I could be wrong. I gave it a wash and the water ran through one hole at the side and came out of the hole at the other side. Just wondered if anyone had an inkling what it could be? Thank you

Ratfish tooth from the mid-jurassic in Denmark
Sauroniops posted a topic in Partners in Paleontology - Member Contributions to Science
Hello there fossil forum! A few of you may have read my post about my 2 trips to Bornholm, a Danish island that holds a lot of different fossiliferous geological layers. I had specifically been digging by a location called "Hasle beach", where mid-jurassic sandstone layers are present. There have been found a few plesiosaur bones/teeth there, as well as 2 possible dinosaur bones, still being described, and also a few footprints. Other than that, mostly what you will find here, is shells, and occasionally hybodont shark teeth. As I mentioned in my last post about Bornholm (you can read it here), I found a ratfish/chimaera tooth together with the drummer from my heavy metal band. Our guitarist and bassist were nearby, as me and the drummer sat in one spot, opening several large eroded sandstones together, when suddenly a small black lump was visible within the orange sandstone. It turned out to be a chimaera tooth. When we were done digging for the 7 days we were there, we handed some of the stuff over to the museum on the island to check it out. I took the chimaera tooth with me home. About 1 and a half month later, a renowned Danish paleontologist made a lecture/presentation about dinosaur finds on Greenland. In between one of the breaks in his presentation, I got to talk to him, and I had taken some of my finds from Bornholm with me, including some plesiosaur bones, and the chimaera tooth. He took some of the stuff with him, to examine closer. He sent some of the bones back last month, saying it was some partial vertebrae fragments, which wouldn't be of interest to the geological institute. However, the chimaera tooth was interesting, as it was unlike other chimaera teeth found at the location. Today I just got an email from the paleontologist, that the tooth is in fact from a new species, and will be included in a scientific article about chimaera-fauna in the Hasle-formation! It has officially been declared "Danekræ", which is a title all "scientifically important" fossil-finds are given. It becomes state-property, and the finder/finders of the fossil are rewarded with some cash, as well as the honors of having their name attached to the find!- 19 replies

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

Hello, I saw this for sale and tempted by it, but is it Allo? Seems pretty small to me. And, is it complete? The base seems crooked, so wondering if it may be half a tooth? Labelled as complete but repaired crack. From Morrison Formation. Thanks

Hello Everyone, I found this eroded partial nodule while on a fossil hunt at Runswick Bay last year. I think it contains part of a fish but I'm not sure of the type. I've had a look at some other Yorkshire fish material, primarily Gyrosteus, but haven't seen anything like it yet. Most of the Gyrosteus material seems to be much bigger then whats in this block. I was wondering if anyone could help me identify what it is, I think I have sections of fin as well as possibly a cluster of ribs eroding out of the block. I've also included an annotated image of the front and back since the material is very difficult to pick out in pictures. I'm sure I have missed a few bits but I drew in everything I can see. Also, is there any way to prep this sort of material? The block is full of calcite veining so I assume manual preparation is near impossible, certainly well beyond my beginner abilities. Any and all information you can give me is greatly appreciated. Thank you, Benton

Hello! As soon as lockdown is over, my friend and I are planning a fossil trip, most likely to the Jurassic coast. Now, we've done Charmouth, Lyme Regis to death. Can anybody recommend any other good locations for finding reptile bits? The find rates don't need to be as high, but it would be nice to try somewhere new

Hello everyone. I wanted to share with you my fossils collection. I started fossils hunting in my area back in the june 2019 and that's what I collected and preparated since then. First of all, my favourite belemnites. I donated one of the largest rostrum (7 intact inches, on the second photo) to the Jurassic Museum in my country, feels good So, let's get started, that's one of twelve full shelves, this one is especially for belemnites

Whats the easiest to get full reptile/amphibian fossils?
Raptor9468 posted a topic in General Fossil Discussion
I was wondering if there are any permian to cretaceous reptile/amphibian fossils that even an newbie like me can acquire without having to dig or pay a huge price for,I looked for permian and triassic stuff and it is really hard to find such things Are barasaurus legal to buy? -
Hello all, I've had two teeth in my collection for many years now. I've recently moved and lost the supplied ID labels that came with them. I've taken this as a nice opportunity to see what others may think they are. I believe if memory serves me right the large tooth (Tooth A in photos) was labeled as a Simolestes. Then the smaller tooth tip (Tooth B in photos) labeled as Liopleurodon. I know both were found in the Wicklesham pit in Faringdon, Oxfordshire, UK. Upon some research, I found an article from 2014 with a Dakosaurus tooth discovered to be the largest in the UK at the time. This tooth bears some resemblance to tooth A but I'm unsure. I've attached a link to the article below. Tooth B has been worn down but still presents with grooves in the enamel. I have also labeled each photo to allow for easier identification when talking about it (Hope this helps!). Im excited to hear what others think. Thanks for reading Link to articles on Dakosaurus- http://www.sci-news.com/paleontology/science-tooth-fossil-dakosaurus-maximus-01954.html

Hi all, after seeing all these nice collections from other members I also want to share the collection of my father and I with you. The collections is of various time periods and sites. We started collecting in 2009 close to home in a quarry nearby Maastricht called 't Rooth (sadly this quarry is close for visitors since 2016). From there on we started visiting other quarries and the collection started too grew massively. We frequently visited the ENCI, Winterswijk and Solnhofen. I will start off with some of the display cabinets

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 forms with field trips and purchases. So I'll start this thread with a few species from the Lower Lias, Lower Pliensbachian Stage, that first made me realise that not all belemnites look the same. This was a time of sudden diversity for the group. Earlier species (Sinemurian) are small and of low diversity, mostly belonging to the genus Nannobelus (= "dwarf dart"). (I'll do those later). All from the Charmouth Mudstone Formation, Stonebarrow Marl Member (formerly "Belemnite Marls"). Charmouth, Dorset, UK. Jamesoni Zone, Polymorphus Subzone. Bairstowius junceus/longissimus (Phillips, Miller). (junceus is the currently accepted name for the large form and longissimus for small, slender ones. The small ones appear to be immature individuals so they should probably all be longissimus which has priority.) A group all collected from the same small fallen block - almost certainly all the same species. (A large collection shows a complete series of intermediate forms, though probable sexual dimorphism divides fatter and thinner adults.) From the same beds - the scarce Coeloteuthis (Clastoteuthis) abrupta (Coeloteuthis is an awkward genus that needs revision - a bit complicated, but basically the original type specimen has been lost and the genus has ended up being based on a lectotype that is a different species and probably genus, and even family...) Just for comparison: "normal" belemnites - species of Passaloteuthis - exist in the same beds and are common. Here are two(?) species, the top two specimens probably being variants of one.

Hi everyone , I found these fossils while picking through micro matrix and am not sure what they are. Does anyone know the genus/species of these finds? They were found in the Forest Marble formation which is bathonian, Jurassic. 1. Interesting tooth. Fish/shark? 2. Another tiny tooth. I would say croc but it looks way too small. 3. a tiny hybodont 4. enamel? 5. no clue 6. bone?

Hi everyone , Since we’re on lockdown, I’ve been processing the little amount of micro matrix I had and a few interesting things have shown up. I’m mainly on the hunt for teeth but they are rather scarce and most of the matrix is composed of shell fragments. Some of the stuff I’ve been finding is crinoid stars, Bryozoans and fish scales. Most of this stuff is tiny and I actually can't tell what it is until I put it under the microscope. I’d be very grateful if you could ID some of the pieces as well. Here’s some of what I’ve found. I have more pictures but will post tomorrow. Here’s an interesting little tooth which I didn’t really do the best job of repairing but it was very small . Here’s what I thinks a little fish scale. I’m actually not sure what this is Here’s the only detailed complete crinoid star I’ve found so far. . Here is an absolutely tiny fish? tooth. I would say it looks croc but I’m not sure croc could possibly this small. I actually thought it was just a shard of a fish scale until I took a closer look under the microscope. And here are some bryzoans (that’s what I think they’re called). Im sorry about my very limited knowledge of these kinds of fossils. More pictures coming . That little tooth above was the second of the only three teeth I’ve found after a month of hunting. The third was so small that I think if it wasn’t originally adhered to the matrix, then it would have fallen through the sieve mesh.
