Here's a partial jaw for sale. Seller doesn't know where in Morocco it's from but it's listed as a plesiosaur jaw. Could it be plesiosaur? I wonder if it's croc @pachy-pleuro-whatnot-odon

Marine reptile hunting at Lyme Regis, UK - April 2023
Paleoworld-101 posted a topic in Fossil Hunting Trips
It's been a while since i posted a proper trip report, so i thought i'd show you guys the spoils from my recent trip to the Lyme Regis area in early April 2023 (collecting from the 3rd to the 9th). I spent the week intensely scouring over the foreshore for any vertebrate fossils that i could, as marine reptiles are my main interest at this particular fossil site. But i found many great invertebrate fossils as well! Especially ammonites and belemnites. These fossils are all Early Jurassic in age, about 200 to 190 million years old, and come from the Blue Lias and Charmouth Mudstone formations. Most of my collecting time was on the beach between Lyme Regis and Charmouth, but i also visited Monmouth Beach west of Lyme Regis, which spectacularly showcases literally thousands of ammonites embedded within the shore platforms. This trip was my 6th to Lyme Regis overall, so i was hoping to find some vertebrate specimens that i hadn't yet found on previous trips. And things proved very successful! Despite the large amount of people on the beach over the Easter break. Firstly, some shots of the beautiful coastline. It really is an amazing place to collect. This is the beach immediately east of Lyme Regis, looking out at Church Cliffs, the Spittles, and Black Ven. This is midway between Lyme Regis and Charmouth, looking east towards Charmouth. A closer view looking towards Charmouth. This is the famous "ammonite pavement" at Monmouth Beach, west of Lyme Regis, where thousands of ammonites can be observed in the shore platform. This Mary Anning statue has recently been erected near the beach access point east of Lyme Regis (within the last year i believe). People were leaving both flowers and fossils here which is lovely. Now to the fossil finds! Including some "as found" pics of fossils lying on the beach, before i picked them up. Starting with a nice section of marine reptile rib. I suspect this is plesiosaur rather than ichthyosaur. The end of some kind of marine reptile limb or phalange. Possibly the end of a plesiosaur phalanx. This is the bottom half of an ichthyosaur humerus. I've drawn the approximate shape of the part that is missing. A small piece of ichthyosaur rib. This is a new one for me. A fragment of hybodontid shark dorsal spine. Although it is just a piece, these are relatively rare on this coast. Perhaps the quintessential marine reptile bone from this coastline, an ichthyosaur vertebra! As found on the beach and then in my hand. Finding these never gets old. This is the top of an ichthyosaur femur. The natural cross section of the bone shaft preserves amazing detail of its growth rings! A small fragment of ichthyosaur jaw, with several rounded cross sections of worn teeth. Something else i had yet to find from this area: marine reptile coprolites! One is quite beach worn, while the other is rather 'fresh'. No pun intended. As-found pictures of marine reptile bone chunks sitting on the beach. Here's a final summary of all the vertebrate finds from the trip. For a weeks worth of searching i'm very happy with this lot! And of course, the invertebrates! I particularly loved some of the larger ammonites, although carrying them off the beach would require a team of people! And these definitely wouldn't fit in my suitcase returning to Australia... A lovely belemnite. This one is a nautilus! Finally, something i wasn't expecting to find. This is a small crustacean from the Upper Greensand (Cretaceous rather than Jurassic). Overall it was a fantastic trip! And i'm looking forward to returning whenever i can. Thanks for checking out this report- 10 replies

Fossil Goal Achieved! Plesiosaur Tooth! Ash Grove Quarry Field Trip
JamieLynn posted a topic in Fossil Hunting Trips
Well, you have probably already seen a few posts about the Dallas Paleontological Society's field trip to Ash Grove Quarry in Midlothian Texas. And Here's ANOTHER ONE! As it turns out, quite a few of us went on the same field trip but DIDN'T REALIZE WE WERE ALL ON THE SAME FIELD TRIP. That's what happens when you are mostly online friends and havn't actually met in real life! That and there were 50 people on the field trip....but it's a big quarry! Sorry I missed connecting in real life with @EPIKLULSXDDDDD, @PaleoPastels and @ClearLake! This actually was my first field trip with DPS and first time to this quarry so I wasn't very sure how things would play out, but we had a beautiful mostly cloudy day with a very nice breeze. As many of you know...quarrys in Texas can be brutal. We've been having surprisingly rainy and coolish weather, so it truly was a great day for hunting. Nice big rain the night before but not super muddy. Driving into the Quarry: I told you, there were a BUNCH of us The guy leading the trip, Francisco was really nice, made sure we were all geared up in our very very fashionable vests. He led us down to the bottom of the quarry where they had just placed a big pile of the strata we were looking for, so we didn't have to wander very far to find the right geology. Roger Farish, the DPS trip leader showed us what we were looking for...greyish rocks with lots of phosphate nodules. Most of the fossils are phosphatized, so the black was somewhat easy to see against the dryer grey, but in areas where it was still wet....that black was a bit tricky to see against the background. My first nice find was a good size Scapanorhynchus (goblin shark) about 3/4 inch long. And then a bit later in some of the pools of water, a lovely vertebra, also 3/4 inchish And there were some very nice big spiders. Don't worry. They were friendly. But.....what made my day, my month, my year was the next find. I found a Plesiosaur tooth. Yep. It was just sitting all nice and pretty on top of a small bank of mud and rocks off to the side, just sitting there waiting for me. It's kinda scrappy, but I don't care. I love it. I literally was shaking when I took it over to Roger F for confirmation it was indeed what I thought it was. So thank you Mother Nature! Here's some cleaned up and better pictures. It is one inch long So after that, I was just happy to wander around, maybe find something else...kind of wanting a Ptychodus tooth but content if I didn't find one and lo and behold....I see a tiny edge sticking out of a big chunk of rock and thought that sure looks like a ptychodus. I chipped it out and yep, a nice, if slightly broken, Ptychodus atcoenses. Not quite as nice as the one @ClearLake found, but I'm pleased with it. So a 3 1/2 hour drive up, a few hours of hunting and then drive back home again turned out to be totally worth it and an epic day for me. I found a plesiosaur tooth!!!!- 35 replies

Found this on a trip to Big Brook yesterday and having a tough time figuring out what it is. The tooth is missing the tip, but appears to be quite narrow, with a strong curve that would eliminate xiphactinus as a possibility. It looks too narrow to me to be a mosasaur tooth and has no visible carinae. Is there any chance it could be a plesiosaur tooth? Thanks for the help!

After finding my pyritized ichthyosaur vertebra in the Grayson Formation last Friday, I decided that it was time to revisit previous exposures I had first discovered three years ago with a fresh set of eyes. I made a trip to several of those spots the following Saturday and one of the fossils I found is another vertebra. I initially wrote it off as a fish vertebra because it was so thick, then decided it wasn't flaky enough to be fish and the two holes on one side meant it must be a shark centrum, then thought maybe it could be an ichthyosaur caudal, and as of now I think it might be a plesiosaur caudal. As you can probably tell, I can be pretty indecisive! I also promise that the grooves on the face of the vertebra going towards the center weren't slips with the dental pick I was using; they were already there. It's about half an inch in diameter and a quarter of an inch thick. Let me know what you all think. This thing has me stumped!

From the album: Texas Cenomanian (Cretaceous)
Unidentified Plesiosaur Cenomanian Texas Found on the same day as another incredible fossil - a coniasaur set to be prepped this summer. Further exploration of the site has not yielded more of the animal, though exploration is extremely slow due to the challenging position of the fossil, so only a foot of rock or so has been explored beyond. Continued trips are necessary. Discovered in July of 2022.- 4 comments

A long time ago In a village not far away .... Barrow on soar is a little village where a famous plesiosaur was excavated in 1851, of the species Atychodracon megacephalus, nicknamed the "Barrow Kipper or just the Kipper ". The plesiosaur was found in a lime pit outside the village ( Leicestershire has a lot of mineral quarry). In the centre of the village on a roundabout is a lovely mosaic which pictures the kipper’s skeleton. The skeleton is now on display at the New Walk Museum in Leicester the first museum We visited today. The village's football club also has the skeleton on its badge too. Also seen today a replica that is in Charnwood Museum, Loughborough. New Walk Museum mosaic barrow on soar football team. Charnwood Museum replica under the floor this does really illustrate the size of the kipper. Cheers Bobby

Today I bought this little gem at the 'Nautilus' fossil fair in Ghent (Belgium). It was sold to me as (and probably will be) a humerus/femur of a juvenile Plesiosaur found at Cap Blanc-Nez. Is this id correct? Is anything more specific to be told about it? Lenght is about 10cm, it's 2.5cm wide. Thanx for any words!

Hi all, Bought this tooth online a while back. It was sold to me as "Ichthyosaurus platyodon" (which I understand to mean Temnodontosaurus platyodon) from Lyme Regis. Likely found by the seller themselves, as I know they occasionally collect fossils there. However, for the following reasons, I'm not sure about this attribution: Overall, the tooth doesn't look like your typical ichthyosaur tooth to me: It has more of an oval rather than round cross-section It's labolingually flattened Messial and distal carinae run the full length of the crown and divide the tooth into labial and lingual parts While fine striations can be seen on one side of the tooth (presumably the lingual side), the other side (which would be the labial) seems entirely smooth - though some traces of rare striations can be seen on the photographs The striations are much more similar to those of crocodile or pliosaur teeth than to the plicidentine condition so typical of ichthyosaurs The horizontal banding on the tooth surface is unfamiliar to me with respect to most marine reptile teeth I have seen, but occurs much more frequently on crocodile teeth of various species I also bought another tooth with the same attribution from the seller, more or less around the same time. This one has no striations whatsoever, has a more rounded base, is less flattened and has a more rounded tip. It also has carinae. I therefore reclassified it as a probable Goniopholis sp. crocodile tooth. Now I know that not having the root makes it more difficult to identify this particular specimen, but I was hoping someone on this forum might be able to help me, as currently it goes without label. I've considered crocodile, plesiosaur and even pliosaur, but all of these have some reservations that prevent final classification. For one, none of these groups have teeth that are typically flattened like this, nor do plesiosaurs (sensu lato, thus including pliosaurs) have carinae. Crocodiles, then again, would either have or not have striations all around the tooth. And what to make of the banding: is this just preservational, or does it reflect the internal structure of the tooth - i.e. outcome of the tooth's ontological growth? Tooth measures 18 mm and is missing the tip. Thanks in advance for your help!

Hi All, I work in a small museum and im currently a geology undergrad, this is the first time in quite sometime that the museum has its own large fossil to prepare. I have some questions, we have an Air-Chisel and other prep tools. But what is the general consensus for getting fossils out of limestone? Particualy vertebrate fossils like these. Cheers, Jayden Squire

Goal: collect all Pierre Shale formation main fossil specimens. During my fossil hunting trips I collect a lot of different fossils but never take the time to figure out what it is exactly. Here I will record my trips and finds but more importantly try to identify what it is. This list will encourage me to not just look for the big marine reptiles but also smaller things I normally ignore. I understand how unrealistic this goal is but it's fun. Any feedback or suggestions are welcomed! Specimens shown on wiki for Pierre shale.

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

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

Hi all! Here's a brief report on Eganovo quarry, a well-known place among local public interested in fossils. It's basically a "summer site": fossiling there is associated with water and lots of mud, highly uncomfortable in cold seasons. The site is situated some 20 km southeast of Moscow. Late Jurassic. The quarry is an unusual place by itself with a strange otherworldly scenery.

Hi, I'm not sure what exactly this is? it is a strange fossil and according to the seller it is a Plesiosaur skull with a few traces of bone? and was found above the ground. Not sure what to make of that but I think I can see some tooth sockets and maybe the eye sockets (unless I am very mistaken), it just has me stumped! thanks for any help
