Liopleurodon Tooth From Oxford Clay, Orton Brick Pit, Peterborough, UK?
Pliosaur posted a topic in Fossil ID
Hello All! Was wondering if this is a possible Liopleurodon tooth? It is from the Orton Brick Pit, a site known for marine fossils dating back 150 million years to the Jurassic period, now a private site closed to the public due to conservation. Tooth measures approximately 2 inches, pictures attached below- 7 replies

In past, I was afraid of the tooth damage, so I put adhesive on the tooth. But adhesive parts turned white, because it didn’t dry properly, so I requested an acquaintance to restore it. Fortunately, removing adhesive was successful. Due to, the striation looks clearer. Here’s check it. Lastly, more closer striations.

I recently acquired this piece. It's a little over an inch long, from the Asfla region of Morocco. It was labeled pliosaur but looking at other pictures online, it appears to favor a Polycotylidae plesiosaur tooth. Thoughts?

I recently found two pliosaur teeth were on sale on online auction site. One was listed as “Simolestes sp.”, and another was identified as “Liopleurodon sp.”. What’s your thoughts? Are they real Jurassic pliosaur teeth, or they belong to something else?

From the album: Eagle Ford Group
Brachaucheninae Pliosaur, North TX Turonian, Cretaceous Dec, 2023 This was a very fragile tooth to prep because it is only a thin fragment on a very weak matrix. After some delicate needlework and b72, I think it came out pretty good.-

Hi everyone, I recently found a marine reptile tooth fossil that was discovered in Stary Oskol, Russia. The tooth is currently labeled as “Pliosaur” by the seller. Considering the prevalent geological age of the Stary Oskol region as Cretaceous, it indicates that the tooth could be from a Cretaceous plesiosaur or pliosaur. However, the absence of enamel striation raises doubts about its identity, as most Cretaceous pliosaur teeth typically exhibit fine striations across the circumference. Any thoughts on this?

While looking at fossils collected by collectors, i discovered a fossil of a pliosaurus tooth from the Tatarstan region. For the first time I saw the teeth of a Tatarstan pliosaurus. If anyone has one, could you show it to me?

Pliosaur tooth from France. Is this possible to Liopleurodon?
Nichet1122 posted a topic in Fossil ID
Hello! Recently, I've got an pliosaur tooth and so excited to get this one because of the rarity. Seller said it is Liopleurodon ferox. But unfortunately seller did not say about fossil's exact information(Formation). He just said it came from La ferme d Argence, Normandie. Is this tooth possible to Liopleurodon ferox? Add some images. Size 3.35 inch. It's definitely looks like genuine pliosaur tooth, but I'm not sure what species it is.- 2 replies

This is a very nicely preserved Pliosaur tooth from Goulmima apparently. It has the details of a Pliosaur tooth. Only question is the color. Lots of them are brown to red colors. This one is grey/black. Could this be from a different location?

My Best Tooth Yet; On My Final North TX Hunt No Less! Kamp Ranch
Mikrogeophagus posted a topic in Fossil Hunting Trips
Even after having a night to sleep on the fact, I'm still in shock. I was tempted to not even go on this trip since part of me wanted my plesiosaur tooth from last week's Woodbine adventure to be my final impression on North TX. The other part of me wanted one last crack at the Kamp Ranch and a new potential site. It's fine to return to already known locations, but I was thirsting for one more journey into unknown territory where the risk of failure is greater, but the taste of victory is sweeter. After swimming/wading a ways, I found the first small outcrop of Kamp Ranch. I've had some previous experience with this layer in the past, and the knowledge I picked up from then proved useful. While most of the outcrop was relatively devoid of vertebrate material, there was a thin pasty layer cemented to the underside of the thickest limestone that proved to be rich in teeth. I pried out the odd Ptychodus tooth here and there, but pretty soon I was out of real estate. The thick limestone slab looked precarious and the rest of the pasty matrix I was after was nestled deep in the crumbly wall. Noticing the slick shale beneath my feet, I decided jumping away from an avalanche was out of the question and it was time to move on. Ptychodus from the outcrop. All P. anonymous except the top right which may be a P. marginalis(?) lateral. On the walk over to the next outcrop, I made sure to scan the loose pieces of Kamp Ranch matrix scattered about. Most of them were only comprised of oyster bits and Collignoniceras woollgari impressions, but once in awhile there would be some shark. I went for a rock with a shiny black Ptychodus anonymous that had caught my eye. As I dug it out to have a closer look, I saw there was a tiny tan mosasaur situated next to it! Unfortunately it's cracked and in super hard material. If I try to bust it out, it will probably explode! Ptychodus anonymous and mosasaur tooth (Russelosaurine?) Just a few feet further I found an absolute heartbreaker. I could see black striations coming from the edge of a slab and my hopes shot up. As I turned the rock, I realized it was a shattered piece of a pliosaur tooth . Don't even think it's worth keeping... Pliosaur tooth, likely Brachauchenius lucasi I picked up my pack and headed to the last outcrop of Kamp Ranch. I was relieved to see the thick limestone was much more secure. As I examined underneath, I had my mind set on small Ptychodus teeth when I almost fell on my back from surprise. Cemented to the slab was a truly astonishing sight: Pliosaur Tooth! If that wasn't crazy enough, just centimeters below was a limb bone jutting out. I got out my excavating gear and carefully went to work. I don't carry b72 in the field, so each tooth fragment was extracted separately. Afterwards, the bone slid out pretty cleanly. I didn't find other similar material, so I'm not sure if the two are associated or it's just coincidence. Maybe someone familiar with reptile anatomy can say if the bone came from a pliosaur. The tooth came in 6 pieces Once I was home, I got straight to cleaning and gluing. The fragments had held up alright along the journey thankfully and the prep went smoothly. By the end, I was holding up the newest and greatest tooth in my collection! It is most likely Brachauchenius lucasi although Megacephalosaurus eulerti is also a rarer possibility (I don't have access to the paper distinguishing their dentition). Both of these pliosaurs represent the youngest pliosaurids in the fossil record which adds some extra coolness factor. That Woodbine plesiosaur tooth (possible basal Polycotylid) I found last week is interestingly tied evolutionarily with the demise of pliosaurs such as B. lucasi. Polycotylids had traditionally been placed in Pliosauridae until more recent findings moved them to Plesiosauroidea instead. This confusion is likely due to convergent evolution. As pliosaurs disappeared in the aftermath of the Cenomanian-Turonian Anoxic Event, it seems some Polycotylids evolved to fill a similar niche, moving away from gracile dentition (like my Woodbine specimen) and into a more robust form similar to B. lucasi. At least that is how I understand it. Brachauchenius lucasi most likely The second half of the neat discoveries is this reptile bone I found several centimeters below the tooth. I'm not sure it's associated. The high energy nature of the Kamp Ranch makes me wonder if it was just coincidence. Anyways, it seems to be a limb bone. If you look closely, you can see toothy scrapes that are probably from scavenging sharks. I tried to look for signs of serrated teeth, but I didn't see anything obvious. Some of the attached matrix is vertebrate rich with tons of little fish verts and other goodies. Anyone know if this is pliosaur in origin? @pachy-pleuro-whatnot-odon Reptile Limb Bone So glad I decided to have one last exploration before my move. I guess it's not like I will never hunt in North TX again, it's just that it will be much, much more rare. I've added so many new, fun, and interesting sites to my list this past half year, I'm a bit sad to leave them all behind. At the same time, I'm itching with excitement to make new discovers in the southern half of our big state. It won't be easy though! Look forward to more trip reports in the not-so-distant future .
