  1. Ichthyosaur paddle digit (Wimereux): hit or miss

    Hi all, Found this stone at Pointe aux Oies in Wimereux two days ago, amongst the pebbles collected next to a shelve down towards sea from the spot where I had found an ichthyosaur vertebra (on matrix) two days before this find. I picked it up because 1) the stone is unusually flat; 2) has exactly the right shape and thickness to it for an ophthalmosaurid ichthyosaur paddle bone (see picture below); 3) has certain ornamentation top and bottom; 4) seems to be of a different type of stone than I've generally come across in the area; and 5) has some weight to it. It vaguely reminds me of paddle bones found in the Oxford Clay at Peterborough. Yet, what makes me doubt, though, is that there is no clear radial ornamentation on either top or bottom of the piece, as would by typical for an ichthyosaur paddle bone. A friend of mine, more familiar with fossils from the region, suggested it could be a crocodile scute, as the ones found further up the coast, but this, to me, seems unlikely, as 1) the ornamentation on my find differs significantly from what's typical for crocodilians; 2) the underside is not flat as it would be for crocodile; and 3) the piece seem to thick for a scute. Size is about 4.4 x 3.4 x 1.4 cm (1.7 x 1.3 x 0.6 ") Brachypterygius extremus paddle from Ichthyosaurs: a day in the life... My piece reminds me of the radius. Now my question is: Is this just a rock - i.e. am I seeing things because I really want to - or is it an actual fossil? Is this an ichthyosaur paddle bone/phalange or something else?
  2. Vertebra?

    Hi, I found this at a Jurassic sight and thought it might a vertebra. Anyone have any ideas as this threw me off quite a bit when trying to I'd it myself! I also found a smaller identical piece which is also photographed belowAt its longest point it is 2.5cm. any help is greatly appreciated. Thanks! P.s. I also have some other fossils from here that I can't id myself about a rib section(?) And some possible tiny fish jaws.
  3. Plesiosaur rib?

    Hi all this is the second Hampton Vale id. I found this when wet sifting through some Hampton Vale Oxford clay. If it were from any other place I would say ammonite but I have only ever heard of the ammonite kosmoceras being found here and they have ridging. With this in mind I thought rib. The only animals with this kind of curve and shape of rib found here are plesiosaur pliosaur and ichthyosaur. I was able to rule out ichthyosaur due to shape and I am thinking plesiosaur rib section. Any confirmation or other help with id would be greatly appreciated. Ps at its longest point it is 1.5cm
  4. Fish jaw?

    I found these fossils in Hampton Vale (it's quite a well known and fosiliferous site). The site is Oxford clay and jurassic. When doing wet sifting I found lots of these fossils all about 3 or 4mm and I think they are all fish jaws as they r way too small for rodents. This is the first of a few posts I will be doing for id on some fossils from there. Any help is greatly appreciated :). The pictures are of a few I found. Thanks, Harry
  5. UK Marine Reptile Teeth

    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
  6. Oxford Clay Vertebra

    Hello, I bought this vertebra today at the Oxford Fossil and Mineral Show. The seller did not know what it belonged to, only that it was found in the Oxford Clay in Orton, Peterborough. Any help on what this came from would be greatly appreciated, thank you.
  7. Hello, this is my first post on the forum so firstly I apologise if I have done anything wrong. I brought these teeth a number of years ago and have only just got round to sorting them out. The first one was listed as Jurassic crocodile tooth and the second as Jurassic Plesiosaur tooth, they both come from the Oxford clay around Peterborough. I would really like to put a species name to these teeth if possible so any help would be greatly appreciated. My initial thoughts were Metriorhynchus for the crocodile tooth and Cryptoclidus for the Plesiosaur but I am a complete amateur and would love some help from professionals. Finding information online about the Oxford clay seems to be very difficult. Thanks in advance for your help.
  8. Just got back from a trip to England - still fighting the jet lag a bit! 7 hours time difference makes for interesting sleep patterns! Thought y'all might want to see what I all I found in Great Britain! Of course, we started in London, doing all the London things, including the Natural History Museum! Got to see Mary Annings plesioarus and mosasaurs. And the archeoptyrix! And the dino room!! And much much much more.....whew. Left London to visit friends in Bury St. Edmund, near Cambridge. We went to see the Sutton Hoo burial near Ramsholt in Suffolk which I had heard of a fossil hunting spot there- didn't really get to look much because there was a boat burning at the docks.....so fire trucks and smoke and commotion. I found out later that the main hunting area was a 45 minute hike from the waterfront, so I kind of missed out. Wasn't really prepared to hike that far, with friends who aren't really into fossil hunting, so I contented myself with poking along the water front and found a couple of little things.... (not the shell, I found that embedded in the dirt at Framlingham Castle, not sure if it is a fossil or just a shell). I'm not really sure what any of them are, the bullet shape I was assuming was a cephalopod, but it might be a phragmocone and I really don't know what the little round one is, perhaps a vertebra? I didn't have a coin for scale, but the little round is 3/4 inch. Next on the fossil tour was Yaxley Hampton Vale lake near Petersborough. I had heard it was a good spot, if somewhat picked over, but I found it to be quite good! I didn't find any ammonites (which I was hoping for) or crinoids (although my friend who was driving found a HUGE crinoid stem - beginners luck, the rat). But found a nice sized belemnite, plus these those neat little white spicule things. I saw them ID'd somewhere a while back (sponges, I think) , but now I can't seem to find what they are called, so if you know, please let me know! A Swan at Yaxley: But the highlight of the trip was a guided tour around Weymouth, with the interesting and outspoken Adrian Davies! He picked us up and toured us all around Portland Island and Weymouth with info on the history of the town plus stops for fossil hunting! First stop was to a cobble beach with "roach stones"...what we in Texas call Rattlesnake Rock. My husband found a dolphin spine washed up (I really wanted to take some of the vertebra, but decided they might not let me back in the US)! You can see all the cobbles around the dolphin. My "roachstones" The view from Portland looking back toward Weymouth: And the best for last - my finds of ammonites (16 of which are pyrite!) , crinoids, belemnites, a phragmocone, a sponge and a bit of bone plus some other stuff: A few more pics of my finds: Me with my nose to the ground- it was a bit chilly and windy...and then I came home to the Texas heat.. And then a day later, I went to the Quarry at Midlothian on a 100 degree day. But that's another story.....
  9. Trip to Yaxley pit, Peterborough, UK

    Here are some interesting small fossils I found on a recent trip. The fossil in the first three pictures is 8mm long. The next two are of a flat fossil about 13mm long
  10. Hey all, I thought I would make a thread to show some of my shark teeth that I have collected from the Oxford Clay formation (mainly the Peterborough Member), feel free to comment if I have misidentified anything! Pre-Apologies, some of them are quite small.. Cheers, Jacob.
  11. Kings dyke & Yaxley Trip

    Hi everyone! Took the two hour drive to Kings dyke on Sunday hoping that the new material that had been dumped would produce. For those who are unsure Kings dyke is a nature reserve situated next to a working brick quarry. Every so often they dump a load of the spoil from the quarry in a area that the public are allowed to search in. In the photo below you can see the working quarry in the background and the fenced in fossil area in the foreground. What i would give to be allowed into the main quarry..... This material is absolutely full of Gryphaea 2D ammonites and sometimes marine reptile bones and fish fossils. Unfortunately on this day, the bones eluded me. I ended up digging in random spots until i found large blocks that were big enough to split and this resulted in some lovely large belemnites with most coming out in a multiple pieces apart from a couple which came out complete. Certainly the largest ones i have ever found. I then drove 20 minutes down to a road to a disused quarry located on the edge of Yaxley. This quarry has nearly been completely flooded however there is a small area where the Oxford Clay is exposed on the surface at the edge of the flooded area. The fossils erode out of the bank on the waters edge so you can either walk along the bank, or, as i and others do, put on waders and sieve the material that is at the bottom of this bank in the water. Before long i had found plenty of smaller ammonites of different species, a single vertebra which looks like it has come from a fish, and what i think is my first ever Ichthyosaur tooth. Albeit just the tip. If anyone can confirm for me that would be brilliant. Length is 9mm. After a few hours my back was in agony and with big black rain clouds threatening i headed off for what should have been a two hour drive home, however due to an accident and a detour i got lost on it took nearly 5 hours... Hope you have enjoyed reading this and have a nice day!
  12. Hey everyone - hope you're all doing all right For the past few days, I was for a short holiday in South England - and while I was in Oxford, I had the chance to see at the Natural History Museum a new, amazing exhibit called Out of the Deep. The display consisted of two remarkable, nearly complete skeletons of marine reptiles - both of them from the ~165-million-year-old Oxford Clay Formation of southern England. One of the skeletons was of a pliosaur (otherwise known as a short-necked plesiosaur) called Peloneustes, which had been discovered in 1994 in Yarnton (Oxfordshire). The other skeleton (nicknamed "Eve"), discovered in Peterborough (Cambridgeshire) in 2014, was of a longer-necked plesiosaur. According to Roger Benson, the skeleton might represent a new species. Both skeletons are really beautiful - and I'd recommend all of you to check them out The Out of the Deep display, with its two plesiosaur skeletons in all their glory Photo credit Oxford University Museum of Natural History Well-preserved mandible from the Peloneustes skeleton The nearly complete skull of "Eve" the long-necked plesiosaur... The Out of the Deep exhibit is truly a must-see!! -Christian
  13. 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
  14. 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
  15. Hello all, Currently digging through boxes I haven't looked through for several years and came across these two ammonites. I thought they were Kosmoceras grossourvrei but they seem to be too coarsely ribbed, Kosmoceras pollucinum maybe? Any help or advice with this would be greatly appreciated. Found in the Lower Oxford Clay of Kings dyke, Cambridgeshire. Callovian stage. Cheers, Jacob.
  16. Hello all, As part of my dissertation I have been sifting for micro-fossils using Braiser's (1980) white spirt method. The samples have yielded a range of micro-fossils, most of which I have been able to identify. However, this has stumped me. I believe it to be a tooth/toothplate from a fish, the enamel texture is similar to tooth textures I have seen before, though I cannot identify the species or if it is one. Any help or advice with this would be greatly appreciated! Cheers, Jacob.
  17. Hello, If you have seen my prior posts, it would appear I'm on a lucky streak... I found the blade of this sharks tooth at the fleet, Weymouth It is from the middle Oxford Clay (Upper callovian) - specifically the Q. Lamberti/ C. scarburgense subzone bondary I believe it is Sphenodus longidens, though it is hard to tell without the root! Any help or thoughts would be much appreciated Cheers, Jacob.
  18. Pre-apologies for the picture, it is rather small and doesn't pick up well on my camera... Nonetheless, can anyone help identify this tooth? I have the name on the tip of my tongue, but my books are not with me to help identify it...
  19. Hello, I am looking for help identifying a specimen collected during field work for my dissertation. The piece was collected from the Lower Oxford Clay (jason zone) in Peterborough, Cambs. I suspect that it is Ischyodus egertoni, but am not positive whatsoever! Any thoughts would be appreciated Cheers, Jacob.
  20. Collected from the K. jason subzone within the Lower Oxford Clay of Peterborough. I thought it could potentially be a palm leaf due to the veins, though wood is prolific - a leaf would be atypical of marine deposits? GBP 1 pence piece for size reference Any help would be much appreciated. Jacob.
  21. As I was putting together labels with photos containing microscopic images of inclusions in coprolites, I came across something that I may have misidentified as a fish tail and vertebrae in a very small coprolite. After looking at it again, the tail looks more like a shrimp or crawfish tail than that of a fish. What I thought were fish vertebrae, look more like crustacean arm joints/elements. Can anyone please confirm this for me? Thanks a bunch! Formation: Oxford Clay (Jurassic - Callovian) Location: Orton Pit, near Peterborough, Cambridgeshire, England
  22. Oxford clay puzzles

    I really feel like I should recognise these, but just don't. I wondered if one was a bivalve shell, but it's unlike any I have found, and the other perhaps an impression of an ammonite. Any help appreciated. Jurassic, Oxford Clay, Peterborough member. @DE&i
  23. Metriorhynchid tooth

    From the album Dinosaurs and Reptiles

    Rooted marine croc tooth from Jurassic
  24. Jurassic fish

    This is my most complete fish, and I found it last year. I went fossiling yesterday and found more fish bits, so hopefully it's a good layer of clay for fish. I thought understanding this one might help me with the individual pieces. More experienced people than me pointed out it's probably a skull, and there are vertebrae at one end (right hand side of first image). But I've been looking at fish skulls and I'm still confused. It looks like a snout at one end, which seems wrong. Is this distorted? I thought it might be Aspidorhynchus as that had a long rostrum, but I think it's more likely to be a leptolepis as they are more common. It could just be I dont understand the skull. Any pointers would be appreciated. Jurassic, from the Oxford Clay, Peterborough formation.
