  1. 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.....
  2. 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
  3. 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.
  4. 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!
  5. 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
  6. 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
  7. 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
  8. 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.
  9. 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.
  10. 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.
  11. 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...
  12. 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.
  13. 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.
  14. 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
  15. 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
  16. Metriorhynchid tooth

    From the album Dinosaurs and Reptiles

    Rooted marine croc tooth from Jurassic
  17. 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.
  18. This post will be ongoing as I am still processing my Oxford Clay and started looking at microfossils in it in 2009, I think. Hoping to start photographing finds very soon. See finds already donated to museum in Partners in Palaeontology - Contributions to Science. 1- Agglutinated foram 2 - Also Agglutinated foram according to museum, weird. Would like to find another photo to confirm. I think I need an Jurassic atlas on the things. Santa take note. Yes I will work out how to stack my microscope photos one day.
  19. Yaxley Fossils

    I went to Yaxley today, and after processing most of my finds I'm left with a few puzzles. I recently found an echinoid spine, and was wondering whether the first one below is part of an echinoid test, The second was picked up as a belemnite, but the cross section looks wrong, and I've seen echinoid spines in museums of a similar shape. The third bobbly one I have no clue, and would be grateful for any suggestions. I've called it Mr Bobbly. Finds are from Yaxley, UK, Jurassic, Lower Oxford Clay, Callovian. ETA: the order of the photos changed as I posted, the first fossil is the round black one in the images, the second is the very pale belemnite-like one, including cross sections, and the third is the long bobbly one.
  20. Strange mark in clay

    I found some great stuff yesterday, but I'm stumped with this one. It is a two dimensional stain in the clay, there are three pieces of it, and I think it is perhaps a burrow, or a trace fossil of some kind. I've seen things I thought were burrows before, but they didn't look like this, so perhaps I was wrong in those instances? Or a different type of burrow. It's a very dark circular mark in the clay. The images without a scale are taken with my microscope camera. ETA Forgot the important bit! Oxford Clay, Peterborough Member, lower Jurassic. They've put new clay in the fossil hunting area, and I'm unsure which layer this is.
  21. Suggestively shaped rock

    I picked this up a year ago as it is convex on both sides and looks a bit like a vertebra. It's from the Jurassic Callovian Lower Oxford Clay at Yaxley, and a year on I still can't decide if it's just a suggestively shaped rock or a very worn vertebra. It's really hard to show the convex shape in the photos. ETA: I meant concave, not convex
  22. Hi, @oxford clay keith @DE&i and anyone with any thoughts on the matter I go to two sites, within a few miles of each other, with exposures of the Oxford Clay. I've been puzzling at the difference between the biotas I find: Yaxley - Lots and lots of crinoid ossicles, vertebralis and surpula. Also plenty of gryphaea, belemnites and ammonites, the latter three dimensional and pyratised. Basically a lot of benthic critters, with some pelagic. King's dyke - No crinoids. No serpula. Haven't found verterbralis. There is evidence of pyrite, but this is usually a dusting over delicately preserved aragonite shells. There are gryphaea, but the benthic fauna seems less diverse. I'm baffled. I thought one possibility could be that Yaxley represents an oyster reef, glued together with serpula tubes. This would provide a firmer base for animals such as crinoids than the usual soupy mud of this period and location. Oyster reefs exist all over the world today, still exist off the coast of Britain, and there are very rare serpulid reefs off the coast of Scotland. Gryphaea are a form of oyster, and these unlike at King's dyke, are really encrusted with fantastic serpula tubes. I thought perhaps the Yaxley exposure was in the Jurassic slightly closer to a shore and sustaining reefs. There are some other important differences between the sites. Yaxley is an eroding former brick quarry, so relatively static, whereas at King's dyke the clay is supplied and renewed by the brick company from different layers of the Oxford Clay, and put on a site for fossil hunters. The preservation is very different, and in part that will be because the latter is fresh clay, just quarried. I could be as much looking at different layers as different locations. Both sites produce marine reptile fossils. But one seems more pelagic than benthic, the other more benthic than pelagic. Preservation bias could be playing a big role. Delicate fossils would not survive at Yaxley in the same way, leaving mostly heavily mineralised, hard fossils. All thought very welcome.
  23. After splitting some clay shales this morning I wondered how these two fossils would have come together. Thank you for looking
  24. Belemnite species

    Following on from a post in the questions forum, I was trying to identify this species of belemnite that I picked up on Friday from the Oxford Clay at Whittlesey, and learn generally how to identify species myself, rather than squeak 'thunderbolt' excitedly. It struck me as unusual partly because its shape is different from most of the belemnites I see in the Oxford Clay, but also because of the strange white coating. Aragonite is preserved at the site, and I thought perhaps it had aragonite around the calcium carbonate rostrum. Sadly it broke as I extracted it from the clay. It is conical, depressed, very acute and has a deep groove. I was using Fossils of the Oxford Clay to identify it, but although it is most similar to Belemnopsis bessina, I then decided it couldn't be because it is not hastate. But rereading the description it does say it can be weakly hastate, and it might be. Also in favour of this specimen being this species is the flattened apex and kidney shaped transverse section caused by the deep groove. I was possibly overthinking things. It would be reassuring to have other people's input Other features include a strange ridge on the reverse. Not seen that before. Also, just for fun, an 8mm belemnite. I'm not expecting to ever identify it, but it's cute and I thought I'd share.
