Looking for info on Temnodontosaurus eurycephalus
pachy-pleuro-whatnot-odon posted a topic in Questions & Answers
Probably one of the most enigmatic species of Temnodontosaurus is Temnodontosaurus eurycephalus, owing to only one skull ever having been found. This particular species is often described as a snub-nosed temnodontosaur with massive teeth and heavy jaw muscles that it probably used to hunt other ichthyosaurs (and other marine reptiles). Its holotype is currently held by the Natural History Museum in London, with the below being some images of it, taken off of Wikipedia: My interest with it, at present, lies with its dentition, with the morphology of its teeth. For I've- 6 replies

Hello to all forum users! Glad to join you. I would like to share photos of some of my findings. Now there is an opportunity to post only a small part - the topic will be gradually supplemented. So, the finds of marine reptiles from the Cenomanian of the Cretaceous period of Ukraine. Several photos of the crown of the Ichthyosaurus tooth.

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

Where are all the British mosasaurs?
pachy-pleuro-whatnot-odon posted a topic in Questions & Answers
Hi all, While I'm aware that current Cretaceous exposures in Britain are largely restricted to the south and east coasts of the islands (see geological map below; source), significant marine deposition is said to have taken place across much of Great Britain from the Aptian onward (source). As such - and especially considering the richness of the record of the marine ecosystem during the Jurassic- one would expect an abundance of marine reptile remains to be known from British Late Cretaceous sediments as well, the epitome of which, of course, would be the -
Looking for unprepared vertebrate fossils
Natalie81 posted a topic in Member Fossil Trades Bulletin Board
Hello, Since all those covid restrictions I haven't got the opportunity to go look for fossils outside of Belgium. So most of our trips from the last year are almost exclusively in the devonian. To get a little change of this I was hoping to find some unprepped vertebrate material, it dousn't have to be complete and I am not afraid of some puzzel work, but the pieces need to be recognisable. I can offer a multitude of different fossils for trade. ( Ammonites, spiriferids, shark teeth, sea-urchins,...) Natalie -
Hi all, I recently became aware that Madagascar appears to have a fully developed and interesting Mesozoic marine reptile record, yet am not particularly able to find any information on them. The only article I have come across is Bardet and Termier, 1990, "Première description de restes de Plésiosaure provenant de Madagascar (gisement de Berere, Campanien)". However, I've been unable to track this article down. As such, I was wondering whether anybody on TFF might have any information on them. Basically, I'm starting from scratch, so would be very interested in the clades of

Pliosaur tooth, or ophthalmosaurid ichthyosaur (Stary Oskol)
pachy-pleuro-whatnot-odon posted a topic in Fossil ID
Hi all, First off, this is not my fossil (though I own a large crow of similar morphology), but one I recently bumped into and found particularly curious. Why? Because it's morphology seems to contradict itself. Described as a Polyptychodon interuptus (no longer considered a valid genus; Madzia [2016]) from the Late Jurassic Volga Beds (?) of Stary Oskol, the tooth appears to have enamel folds consistent with what one might expect from an ophthalmosaurid ichthyosaur, such as Platypterygius sp.. The root, however, is smooth and round, with a hollow base, which, unlike the rectangula- 13 replies

Marine Reptile Bone Collection from Lyme Regis and Charmouth (England)
Paleoworld-101 posted a topic in Member Collections
I've spent a fair amount of time now combing the beaches around Lyme Regis and Charmouth in Dorset, England, and thought i would put together a topic that presents all of my marine reptile bone finds (so far) in one place. The fossils here are Early Jurassic in age, approx. 195-190 million years old and come predominantly from the Blue Lias and Charmouth Mudstone formations. I first visited this area in 2013 with the simple goal of finding at least one ichthyosaur vertebra, and now after three subsequent trips in 2014, 2017 and 2019, i've put together a far better assortment of finds than i co- 24 replies

Hi everyone, I got offered this pair of marine reptile teeth as those of ichthyosaurs, but am having a hard time making my mind up about their identification. I'd therefore like to ask for your opinions. The teeth were found during works around Nancy back in 2004, and, based on other ichthyosaur finds from the region, likely dates the Toarcian stage of the Early Jurassic (though, from what I can tell, Oxfordian marine deposits are also accessible in the area). This makes them roughly the same age as material from the Posidonia Shale/Holzmaden and Whitby, bu

Hi all, I visited Aust Cliff in South Gloucestershire, UK for a couple of hours last week. I wasn't expecting much as I know how heavily collected it is, but got a few bits of interest which I was happy with under the circumstances. I'd be interested in educated takes on a couple of bits of bone bed I found there at least, especially this first piece that contains what I believe to be multiple bone fragments as well as coprolite pieces and lots of small black fragments - not sure if scales, teeth or what. Here's a view showing what I imagine is one end of a reptile limb bone - coul

Out of the Deep - Marine reptiles at the Oxford University Museum of Natural History
The Amateur Paleontologist posted a topic in A Trip to the Museum
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- 1 reply

An opportunity for TFF members to help us create better programs
fossilsonwheels posted a topic in General Fossil Discussion
We had two really great Dinosaur programs this week. We have two more Dino programs and a shark program next week too so things are rolling along very nicely for us. I did notice this week that we are missing out on an opportunity to give a broader picture of the paleoecology of the dinosaur era. The kids yesterday wanted to see Pterosaur and marine reptile fossils. We had a chance to really explain the difference between those reptiles and dinosaurs because we have yet to acquire those fossils. I wanted to open this topic to TFF members because I respect the knowledge of fossils a- 23 replies

Hi everyone, With this thread I wanted to start a discussion about what the feeding habits would be for most mosasaur species, how you think they would have fed. I personally love mosasaurs, they are one of my favorite prehistoric animals for a number of reasons and I’ve recently even bought my first Prognathodon jaw and I also live in an area that is not only known for their fossils but also for the discovery of mosasaurs. I’ve been doing a bit of reading lately about mosasaurs but I can’t really find anything difinitive on their feeding habits. Their diet yes. B
