Hi guys, I’m thinking this is croc due to the carina, any thoughts on species? Thanks

Oxford Clay, Peterborough Member, Jurassic, Callovian, Cambridgeshire. I found this while fossil hunting in too much heat yesterday. I'm intrigued by the row of circles. I thought possibly decapod ornamentation, or something worm related. Thoughts and suggestions greatly appreciated.

New longirostrine pliosaur described from the Oxford Clay
pachy-pleuro-whatnot-odon posted a topic in Fossil News
Hi all, Just came across the exciting news that a new pliosaur genus and species has been described from the Callovian stage of the Oxford Clay near Yarnton in Oxfordshire. Dubbed Eardasaurus powelli (Powel's Yarnton lizard), it's a longirostrine thalassophonean pliosaur that is slightly more derived than Peloneustes philarchus (with which it shares numerous anatomical features) and forms a sister taxon to "Pliosaurus", Simolestes, Liopleurodon, Pliosaurus and brachaucheninae. A feature of particular interest in the dentition of this new species is the presence of connecting carina-like apicobasal ridges on some of its teeth. The article describing Eardasaurus powelli can be found here. -
Jurassic, Callovian, Oxford Clay, Peterborough Member. I found three this weekend I'm unsure about and would appreciate your thoughts. The first I think might be a decapod carapace.

Jurassic, Callovian, Oxford Clay, Peterborough Member, Yaxley, Cambridgeshire. The closest thing I can think of to what this looks like is a belemnite, but the overall shape is wrong, and the cross-section is very wrong for belemnites I've found at this site and elsewhere. I haven't completely ruled that out though, and opinions would be appreciated.

Jurassic, Callovian, Oxford Clay, Peterborough Member, Yaxley, Cambridgeshire I've found a few of these recently, and been trying to puzzle them out. I had thought they might be crab claws. Today I found my largest and best preserved one so far. I can clearly see plates, but I haven't found plates on images of Jurassic crustaceans, including in Martill. What it more looks like is the diagram of Ophiuroids in the book, which is what @JamieLynn, suggested might be the case, due to the plates. I have found brittle star at the site before, but the preservation was very different, not at all pyratised. So I'm wondering if this is Ophiroid, crustacean or something else entirely. If crustacean I was wondering about Thalassinidea, because I find so many burrows. I've attached images of the fossil and images from this article for comparison: https://www.cambridge.org/core/journals/journal-of-paleontology/article/brittle-stars-from-the-british-oxford-clay-unexpected-ophiuroid-diversity-on-jurassic-sublittoral-mud-bottoms/8B34E184DFCF1CEEE275194CE2498B17 Any help would be greatly appreciated. The ends I find particularly fascinating.

As it's too stormy to collect fossils... Jurassic, Callovian, Oxford Clay, Peterborough Member, Whittlesey, Cambridgeshire. This was something very odd I found from a concretion in the Oxford Clay. They are great for three dimensional fossils such as ammonites. It looks like wood, in which case it's my first bit that isn't carbonised, or possibly bone. It could also simply be mineral. Another possibility is fish. I really wish there was more of it, that might have cleared it up, and would appreciate your thoughts.

Oxford clay, Peterborough Member, Jurassic, Callovian, Whittlesey in Cambridgeshire I collected this a few years ago, and I'm unclear whether it's a large cephalopod hook, or part of a fish, or something else entirely. Any assistance would be greatly appreciated.

Jurassic, Callovian, Oxford clay, Peterborough Member, near Yaxley in Cambridgeshire. These are fragments I've picked up over time, wondering if they have bone texture or not. The bits I have that are unequivocally bone have better indicators. Opinions would be very welcome. The first I keep in my miscellaneous pile. These are all the same piece of rock. With something so small, even if it is bone, is it something that is potentially identifiable?

I got the chance to go to the Oxford Clay twice over the last few days. I'm always looking for echinoderms at this site, and I prefer this one in winter when the vegetation has died back and I can spot lots of small, delicate detail. These are some if my favourite finds from the last few days.

Oxford clay, Peterborough Member, Jurassic, Callovian, near Yaxley in Cambridgeshire. I spent the morning getting muddy in wet clay, and found this. I think it might be part of a hybodont spine, or other ornate fish spine. I've collected a fragment of hybodont spine from this site before. The surface does seem to be enamel, and the shape is slightly curved. Any assistance greatly appreciated.

I'm trying to determine if these are echinoid. I found these two on an Oxford Clay trip yesterday, Jurassic, Callovian, Peterborough Member, near Yaxley in Cambridgeshire. The first is, I think, a partial echinoid spine. My only doubts are because it's quite different from the others I've found at the site, it's a very different pattern. I would appreciate another opinion. The second has completely confused me. It looks black, so I thought it was pyrite, but when I photographed it, it's clearly a completely different material. It's a very odd shape, like a tiny snowman, and the only thing I thought it might be is a mamelon from an echinoid tubercle. I don't have anything else like this, and the different material puzzles me. I would really appreciate opinions on this.

It's been a sunny and very, very cold day. Most of the finds at the Yaxley site are small and intricate, lots of crinoid ossicles. What pops depends a lot on the weather conditions - today I found a lot of lighter coloured fossils, including my first coprolite from this site. There are a few I think I'll ask for help to ID.

I convinced my friend in England to send me some matrix from the Oxford Clay site I have the pleasure of hunting a few years ago. I really wanted to see what I could find in the micro stuff! He packed up a "Fosters sized package of Pay Dirt" as he referred to it and I got it in the mail a couple of weeks ago. It didn't take me long to go through it because I just couldn't stop! So many beautiful tiny fossils!! Star Crinoids, Belemnites, Ammonites, all of those I expected to find. What I was surprised to find was lots of tiny crab claws, couple of shark teeth and some possible Starfish ossicles! First the Ammonites: I am over the moon with my new favorite fossil: a Kosomceras spinosum. Even has a little bit of nacre still on it! 6mm I found an even better preserved one too, but the one with the nacre is special. On my previous hunt in this spot, all I had found were the Quenstedtoceras ammonites. They are still really cool too.... 1 cm Then there is this beauty which I am not sure what it is, but it might be Distichoceras bicostatum 5mm I found so many little crab claws and legs! Really elaborate ones and very simple ones: 3mm And of course, the crinoids - 5mm Some lovey little gastropods, including a really nice pyritized one: 5mm I think it's a Dicroloma trifida Not sure what these two are - both 3mm One of my unexpected surprises...this little tooth! 3mm And I THINK these might be starfish ossicles? If so, that would be really cool. They look an awful lot like the starfish ossicles we find in the Texas Cretaceous. But they might also just be crinoid bits. 2mm And last but not least- a little worm tube. I liked the crenulated edge on the bottom 3mm

Hi, I wanted to ask about this marine reptile tooth from the Oxford Clay in England. The seller has listed it as a Pliosaur tooth belonging to the species Simolestes Vorax, and I wanted to check the id. Thanks in advance!

Caturus ?megadontus MARTILL 1985 (?= ?Osteorachis leedsi WOODWARD 1897) Jurassic, Callovian Oxford Clay, Peterborough Member Kings dyke, Whittlesey, Peterborough, Cambridgeshire, UK A tooth of the large, macropredatory caturid Caturus ?megadontus MARTILL 1985. MARTILL & HUDSON 1991 consider this species potentially synonymous with the contemporaneous and highly fragmentary caturid ?Osterorachis leedsi WOODWARD 1897, which would make ‘Caturus leedsi’ the valid name for this taxon. -

Pachycormidae WOODWARD 1895 indet. Jurassic, Callovian Oxford Clay, Peterborough Member [ A ] Orton Pit [ B ] Hampton Lakes, Peterborough, Cambridgeshire, UK Teeth from indeterminate, predatory pachycormid fish. Likely pertaining to either 'Hypsocormus' leedsi SMITH & WOODWARD 1889 or 'Hypsocormus' tenuirostris SMITH & WOODWARD 1889, which can be distinguished only by characters of the rostrum. Neither species actually belongs to Hypsocormus WAGNER 1860 according to MAXWELL et al. 2020, but are closer to more derived, macropredatory pachycormids like Orthocormus WEITZEL 1930, though their exact affinities remain indeterminate due to their highly fragmentary nature.
