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-

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.

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!

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,

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?

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 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.

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 sh

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

What's covering my plesiosaur vertebra? How to clean
pachy-pleuro-whatnot-odon posted a topic in Fossil Preparation
Hi all, I recently decided to buy the below plesiosaur vertebra after having seen it for a long, long time. It dates to the Callovian of the Oxford Clay and was found at Peterborough. I suspect it may be attributed to Muraenosaurus leedsi, as it comes from a cryptoclidid plesiosaur, but is both larger and more elongate that the typical Oxford Clay Cryptoclidus vertebrae I'm familiar with. Supposedly coming from an old collection, it has a blackened exterior that doesn't cover the entire piece, with the more common buff colour visible underneath. As such, I expecte -
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

Hi all, I've had the below piece in my collection for a number of years now, having acquired it thinking it was a juvenile plesiosaur propodial. It comes from the Oxford Clay of Peterborough and is of Callovian Jurassic age. However, when recently doing some research towards answering another question on TFF, I realised that - even though there's some plastic deformation going on - it doesn't quite look like the juvenile plesiosaur propodial I have from the rhaetic at Aust, nor does it look like a plesiosaur propodial

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 Orthocor -

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. -

Kimmeridgian Clay alligatoroid or Oxford Clay pliosaur tooth
pachy-pleuro-whatnot-odon posted a topic in Fossil ID
Hi everyone, I recently bought this tooth on a whim. It was described as Diplocynodon sp. from the Kimmeridge Clay and reworked into the Albian-age Faringdon Sponge Gravels at the Wicklesham Pit. However, this description is obviously wrong in either species attribution or locality, since Diplocynodon is an alligatoroid genus dating to the Paleocene to middle Miocene, and could therefore not possibly have been found in the Sponge Gravels as Wicklesham Pit. Going by the label that came with the tooth, however, the seller whom I bought the- 10 replies
