Listed in a sales site is this fossil. It's from the kimmeridgian and measures 3.4 * 4.4 cm long. The seller listed it as a possible marine crocodile, but is it possible it's plesiosaur due to the striations? @pachy-pleuro-whatnot-odon

Is it a pliosaur skull or something else?

My kiddo and I made a trip to our favorite cretaceous spot in central Texas. We've been hoping to find a certain type of rock with the hopes of finding a coniasaur or other cenomanian or turonian treasures. This trip a found a medium sized slab in about 8 inches of water. The slab showed white shells and was crumbly. I gently overturned it and took a look. I was very surprised to see a pliosaur tooth. I knew it was possible at this site but I didn't expect to find one. Unfortunately, my faithful assist had slipped and fallen in the water and was now shivering so I decide to pack up the rock and take it home. To give it a shower. In the bathtub. I then sorted through the flaky, sandy dark shell-filled shell. It really smelled like petroleum, and was loaded with teeth and bits. Long story short. I found a nice pliosaur tooth, what I think is a plesiosaur tooth and plesiosaur paddle bone. I also found a knobby, circular-ish dark bone piece, and some sort of fang/claw... The knobby thing is probably a mosasaur kneecap or fossilized snake head. We also found some shark teeth, and hunk of flaky fish bone. It was a fun hunt and I hope I'm right about the plesiosaur tooth and paddle bone, and the mosasaur kneecap or fossilized snake head! Jackito

Recently, my good friend Carter ( @Jackito ) found my personal holy grail of Texas Cretaceous sharks - Pseudomegachasma comanchensis While I knew of the existence of the genus here in Texas, I didn't know much about the teeth themselves as I never was really that convinced I'd ever find one. But Carter's find proved it's possible, and what's better... he found it at a site we both knew of! So, we went out together in an effort to find another. What's better is that I had suspicions about that site's age for a while, and the finding of his tooth attests to the late cenomanian-early turonian (ish) range. Prior to this, I assumed it was middle Turonian like the exposures nearby, and while I find the middle Turonian a greatly interesting time, I've been keen to find cenomanian strata due to it's ability to produce very occasional Coniasaur, Pliosaur and Pseudomegachasma material. It was out first time hunting this area together, and it turns out my usual primary spot of interest is maybe 40 yards from his. He showed me the "giving boulder", and it rapidly started living up to its reputation. Carter may be "new" to fossil hunting, but his research ability and persistence is that of a seasoned veteran, and his knack for rare sharks (such as his Cretoxyrhina symphyseal, his maastrichtian nurse shark tooth, his Pseudomegachasma and huge maastrichtian saw shark rostral tooth) is astonishing. Rapidly, the finds started flowing - for the most part tiny Squalicorax falcatus and Ptychodus of various species, and some really nice teeth from other species began popping up as well: Lovely Cretoxyrhina mantelli with broken root lobes: Squalicorax falcatus. It's easy to imagine these as the Cretaceous equivalent to tiger sharks, both from tooth morphology and their opportunist natures. What looks like Cretolamna - personally an uncommon genus for me One of the larger specimens of the 15 or so Ptychodus Carter found in "the giving boulder" I then found the most unusual Ptychodus tooth I've encountered - perhaps partially digested? @LSCHNELLE It was soon after seeing this that I made a find I have long dreamed of... I was working on the same slab that produced the strange Ptychodus tooth, which I pulled from the bank not even 10 feet away from where Carter was making crazy finds of his own in the Giving Boulder.... when I saw this: It's like I was hit with a shock wave, it sent me absolutely reeling. I lost all inhibition, released a string of not so appropriate words, and fell to my knees, only to get up and start pacing in circles repeating the same not so appropriate words interrupted by cheers. With my explosive reaction, Carter at first assumed I smushed a finger under a falling hammer. I shakily said "no... Pliosaur tooth". He saw it, and while his reaction was much more controlled than mine, many subsequent curses still followed. We were delighted, but any random passerby wouldn't have known from looking at us This was absolutely electric. Most of my best finds I was unsure of upon discovery - but with this I instantly knew, so the subsequent adrenaline and then adrenaline crash meant I had to take a long recovery before I started poking around again. Right as I got back into it, Carter made another crazy find - this time a beautiful Ptychodus occidentalis of great size and fantastic condition. It's funny, because prior to the P. occidantalis I found at a different site a day or two before, I had never even seen one in person, yet on this day we found a couple - though Carter's was by many, many orders of magnitude the largest: Everything was carefully wrapped up and taken home, and so concluded my last hunt before moving to my new college. No Pseudomegachasma, but I cannot complain in the slightest with the bycatch of a long awaited goal of mine. -------------------------------------------------------------------------------- That was yesterday - today was trip number two.. which was moving into my flat in College Station, where I'm continuing my journey more formally as a student of paleontology (though my major is Biology, but you get what I mean) at A&M. It's intimidating moving out from home for the first time, and I had a harder time with it than I thought I would. But, then I remind myself why I'm here and what I'm here to do, and I'm newly determined. Here I am now, in my new room for the first time ever - all in the pursuit of a passion that started here on the forum. I cannot thank you guys enough - I know it seems silly thanking folks on the internet, many of whom I've never met, but without the community here I wouldn't be here either. I noticed the arrangement on my desk earlier - and I snapped a photo, because it captures the energy of what my next two years here will hopefully be like. In the photo are some paleo books I've brought, my field watch that has somehow survived every adventure and misadventure I've put it though in the last 8 months, and a travel box containing two specimens: The Pliosaur tooth that I'm ever so slowly prepping (updates on that will be in this thread), and my Hadrodus hewletti tooth. Update: The prep is finally finished! Very happy with this fossil. Only needed glue once, near the root. Soon I'll drown the whole thing in some 3% paraloid solution.

Hi, Wanted to get some opinions on this tooth. The tooth is from a Pliosaur with a root attached, what I want to know is if the root belongs to the crown. There is some matrix around part of the crown and extends just past the root which is my main concern. My initial thoughts are that the tooth and the root belong together so I just want to see if everything looks alright! thank you

Hi everyone, can you tell me what tooth it is? some tell me it's Pliosaur but I don't see many similarities to other pliosaur teeth I've seen around.

Came across this tooth, the location is: Severst Sandstone Formation Volga River Region, Russia Late Jurassic 145 Mya. The striations tells me it's ichthyosaur, but the root looks pliosaur to me, do I'm curious. What do people here think? It's 34 mm long @pachy-pleuro-whatnot-odon

Finally got the display ready for a large pliosaurus jaw section and tooth fragment (pliosaurus kevani) from Kimmeridgian Clay, Weymouth Bay, Dorset UK Smaller tooth fragment in individual case is Pliosaurus Ferox from Oxford Clay, Peterborough UK 160 million years ago attached close up pictures below thanks for looking! Happy collecting!

This tooth hails from the goulmima, the striations tell me it's pliosaur but I'm not sure. What do people here think? @pachy-pleuro-whatnot-odon

Hello! Looking for a pliosaur tooth if anyone has, please message me and I can see what I have to trade! Condition and size does not matter, however would prefer a UK pliosaur tooth if possible, thanks!

Dredged from the Smallmouth Sands off Weymouth Harbor, Dorset. Specimen is from the Late Jurassic Epoch, Kimmeridgian Age Clay - between 157.3 to 152.1 +/- Ma (million years ago). Specimen has an exposed tooth (root portion) with enamel measuring 4.72 inches in length and 1.67 inches in width (see measurements all taken with digital calipers). Other measurements include 3.38" in specimen width (maxillary bone) Tooth position appears to be tooth #6 from the very tip of the snout, including the two tiny teeth at the terminus. This is based on angle of projection, texture, and the distinctive bone seam that is visible in some of the photos (#12 in particular) as well as the diagram of P. kevani. Tooth position is indicated via a red dot on diagram. There are also sensory pits (foramina) visible on the outer side of the specimen, as well as exposed bone on the inside portion. A few holes bored in the bone from some sort of marine organism (worms perhaps) prior to fossilization.

Hello! Curious if this could be a teeth from pliosaur Simolestes Vorax Teeth does exhibit signs on crushing and measures approximately 30mm, has signs of striations common with pliosaur teeth Additional Details Jurassic, Oxford Clay Peterborough Cambridgeshire UK Attached pictures

I know this pliosaur tooth has been discussed early in another post, but here are more pictures with true colour (I guess) provided by the seller. The true locality of this tooth remains unknown although the seller claimed it was from Oxford Clay Formation, England. Does this tooth belong to Liopleurodon Ferox or Cretaceous pliosaur?

Hi, I was wondering how this tooth looks? I think it is all natural but there is a part around the middle of the crown that could be just the preservation, but would like to get a second opinion on it (there are still striations through it). Thanks!

The seller told me that both teeth belong to Brachauchenius lucasi. What do people here think?

I've come a long way and hope to go a long way still. It's almost embarrassing to show now- but here's my first ever post on here, just three days after my interest in paleontology first ignited

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.

Hey can anyone help me to id this tooth please it from Russia Belgorod region it's pliosaur or ichthyosaurus

Hi, I think this is a partial Pliosaur tooth, just wanted to ask.for confirmation. Thanks.

Hi, Just wanted confirmation about whether this tooth from Morocco is Pliosaur or Polycotylid. The crown is somewhat small, but there are still striations on it. I lean towards Pliosaur but I'm not 100% sure at this point. Thank you!

I was able to obtain a couple of fossils found on the western coast line of France. The first one is presumably a piece of paddle bone from the upper tithonian, found between Wimereux and Cap de la Crèche. It measures about 220 x 160 x 65mm. Very heavy. The second is a vertebra found between Cap d'Alprech and Equihen (Tithonian). Measuring about 80 x 65 x 35mm. Could these be pliosaur or rather plesiosaur fossils? I'm sure they are too worn to identify better than sp.? Thanx for notes!
