Hi everyone. I recently liberated this rather nice ammonite from a block found in a ploughed field near Chippenham, Wiltshire, UK. I believe it to be a Quenstedtoceras from the Kellaways beds (Callovian age). I'd really appreciate it if a more learned member could confirm this. My track record for self ID's thus far has been atrocious!

Fossil hunting weekend to Falaises des Vaches Noires (Jurassic of France) + museum visit
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Last week we went on a weekend trip with our fossil club the BVP to go on a fossil hunt to the jurassic clay cliffs "Falaises de Vaches Noires" between Houlgate & Villers-Sur-Mer in Normandy, France. https://www.paleontica.org/locations/fossil/68 The famous cliffs of Vaches Noires date back to the Jurassic period, and span both the Callovian & Oxfordian stages (166 - 157 mya) and the Cretaceous period spanning the Cenomanian (100 - 94 mya). Back in the jurassic this area was a rich marine environment and fossils that can be found here are man- 30 replies

Hello, I found this fossil in the center of France, in the loire valley. There you can find ammonites, echinoderms, seashells.. all marine animals. Unfortunately I'm not able to identify this one, it looks like a tooth to me but I'm not sure. Dimensions: 2cm

Vaches Noires: plesiosaur tooth or fish tooth after all?
pachy-pleuro-whatnot-odon posted a topic in Fossil ID
Hi all, Last summer, while out hunting at the Vaches Noires on the Normandy coast of France, we found the below tooth in the Marnes de Dives (upper Callovian) . I extracted it from its matrix in order to be able to tell with confidence whether carinae are present or not and thus whether the tooth could be metriorhynchid - which I thought, at the time, to be the only other major contender. Carinae are not present. As such, I then arrived at the conclusion that the tooth is plesiosaurian, and in absence of striations - anastomosing or other - that it probably belonge- 44 replies

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 This has enamel, and is the colour I associate with fish remains. Enamel made me think dentition or scale of some kind, but I'm puzzled by the shape. It has a couple of prominent tubercles, which made me think teeth or scale. Any pointers would be greatly appreciated.

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,

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

I guess as you get older, you get a little more crazy. I had sworn to slow down a bit, particularly after my exhausting hike down the mountain recently, so I'd been visiting easy-to-work sites like the ditch and the shark tooth exposure the last few weeks. But then my colleague told me that he'd opened up another section at the Callovian site in the Wutach Valley and that I should have a look at it. Maybe you can make some good finds. Well, why not? So off I went today. At this site you have to remove a lot of overburden to get at the good horizons and then you're whacking away at a hard

These two coprolites have the most visible and interesting bits to them of any I have found. I've been trying to work out what the bits are, and I think they're bits of fish, from the colour and size, but I'd value more opinions! They are from the Oxford Clay, Jurassic, Callovian, Peterborough Member, and the first has colours I associate with fish remains I've found on the site. I don't really understand the dark pattern on the back. ETA: Sorry, I think this should have been posted in the coprolite sticky!

I'm trying to get to one Oxford Clay site pretty frequently, and it did not disappoint. I found my best gastropods from the site this weekend. I thought I had found two pieces of crinoid, but when I got home found it was four. More ammonite as well. Even better, I managed to not bring home any living creatures. Last time I had a caterpillar clinging to an ammonite.

These are from the Oxford Clay in Cambridgeshire, Callovian, Peterborough Member at Yaxley in Cambridgeshire and for one reason or another have stumped me. I'm not convinced these are all fossils. The first doesn't quite look like the oolitic limestone I have, but it's what they remind me of, and I think they may be oolites rather than a fossil.

Hi all! This is a small trip report from a quarry by the town of Mikhaylov, Ryzan Oblast, situated in 200 km from Moscow. The place is very well known among the public interested in fossils, especially ammonite collectors. There are 4 quarries in a tight group, operated by different companies. Mikhaylov quarry is the most famous of them. The experience is very similar to that of other Callovian - Oxfordian quarries (in my previous reports), but ammonites suddenly take the place of gastropods! Pretty exciting, isn't it? Unfortunately there are not many spoil piles as Jurassic overburd
