Hello, Found an online sale of an indet. Raptor claw, see the link below. edit: it is something that somebody else has for sale and I decided not to purchase it. Found it unfair to have it listed here as potential fake without any clear answer. Therefore I deleted the photo’s, best answer is a link to similar fossils, so thats the informative value of this post.

Hello, i saw this unidentified reptile jaw from morocco for sale today. Does anyone know to what it once belonged ? The tooth socket is oval and the jaw seems to have had a little lip which now had erodet away. So Spinosaurus maybe ?

please help me identify this tooth, found in java island, indonesia the height almost 10 centimeter

Piggybacking off of the fantastic trip report @Jared C wrote about our Eocene excursion, I thought I'd go ahead and publish an account of the solo expedition I embarked on several days prior. Some of you who are familiar with my past endeavors in the fossil rich creeks and constructions of North Texas may know that dinosaur material has been a huge goal of mine for a while now. The Woodbine offers a shot at fulfilling such a dream, though dinosaurs are still very difficult to come by. Luckily, the uniqueness of its environment means that a day without a dino is by no means an unsuccessful one as a plethora of other strange and wonderful things can be found in their stead. After an early start, I set out with a sizeable list of new sites in the Upper Woodbine. There were some mild successes to start, but to keep things concise I will only speak of the final and most productive spot. By now it was midafternoon and the winds were howling at full force. After floating about, examining various chunks of oyster hash, I at last reached a stopping point. Before me was a massive boulder, the size of a car, with a fantastically complex arrangement of debris cemented to one face. From afar it was just a greyish mess, but up close I could pick apart the various oyster shells, driftwood, Thalassanoides, etc. This mixture of debris and later considerations led me to believe that I was gazing upon an ancient storm deposit. Oyster shell hash Up until this point, I had been unsuccessful in finding any sign of vertebrates. I laid myself upon the slanted body of the boulder and got my face as close as possible to its heavily ornamented surface. Like a visual puzzle of sorts, it was very inviting to look at. Intuition told me that there had to have been something of worth hidden within the noise. Phosphate and carbonized wood It took a bit of time, but sure enough I eventually found a tiny pebble of phosphate lost in between the fissure to some branching burrow. The familiar sheen immediately reminded me of the jet black teeth I had once pulled out of the basal Atco conglomerate. With a little more wind in my sails, I continued perusing until I was met with something much more substantial. First phosphatic Cretodus semiplicatus of the day I had found a beautiful Cretodus semiplicatus. To those whom the Woodbine is foreign, such a find may seem pretty lucky as Cretodus is usually a rarity in most places. However, the marginal marine deposition of the group means that coastal predators are represented in very high numbers, so much so that C. semiplicatus is often the most common taxon of large shark to be found. Contrast this with the deeper waters of the slightly younger Bouldin Flags Fm in Central TX, where the same species occurs in much smaller numbers (though admittedly the individual sizes of the teeth are often considerably bigger). Anyways, I got to busting it out which proved difficult. The high density of durable oyster shells halted my progress greatly. Somehow I managed to extract the tooth as a clean chip without it poofing away into a million fine particles. From there, I began finding a large quantity of phosphatic bone material. Most were reptilian in nature and either obviously belonged to turtle or likely belonged to a croc. Sadly, the resilient nature of the matrix and fragility of the bones made a clean extraction more or less impossible... for me at least. Croc vert likely Terminonaris cf. robusta T Turtle elements Random ammonite fragment As my walking continued I began finding some occurrences of sandier depositions that were much easier to dig through and even richer with phosphate. What surprised me most, however, was their appearance. C. semiplicatus in situ In my eyes, those pictures above look as though they could have been taken along the shores of any sandy beach saturated with seashells. The soft sand was so loosely packed, the slightest pressure could disturb the granules and send them drifting away. As I scanned, I couldn't help but imagine the tropical storm or hurricane that must have taken place here 96 million years ago in order to create this flash-frozen formation. The wind suddenly felt of an ocean breeze, and the cloudy backdrop like a Mesozoic sky in recovery from absolute chaos; Alone, I wandered the shore. A couple of croc teeth. Likely Terminonaris cf. robusta To round off the day, I found some beautiful, though damaged, croc teeth. Like the critters asleep in this dune, it seemed I had lost track of time, so I made my way home. ~~~~~~~~~~~~~~ I have a bit of micro matrix to go through, but as of now, these are the species of vertebrates found: Cretodus semiplicatus Cenocarcharias tenuiplicatus Meristodonoides rajkovichi Pseudohypolophus mcnultyi Some nice pycnodont teeth were found Mostly Haimirichia amonensis, but I will take a closer look later Terminonaris cf. robusta I really thought I saw a dino tooth sticking out of the sand when I first spotted this. Actually it is an inarticulate brachiopod ( @Tidgy's Dad enjoy!) called Lingula subspatula. Thanks for reading!

Hello there! It came from Maevarano formation, Berivotra, Madagascar. I have never seen teeth in this shape before in this place. Can you help me? Thank you. Is it Simosuchus?(It is a collection of my friend.)

I got back out to the Potomac river yesterday to search along the Paleocene exposures for some more prehistoric treasures. I got to the beach around 8am and had a couple hours till low tide, the water was calm and clear enough to where I could easily see out in the deeper water. Pretty soon after beginning my hike I found a really nice 1.23” crocodile tooth rolling around right on the shore line. It slowed down for a little while after that only find a couple busted Otodus teeth and a nice sand tiger here and there. Once I got around the bend to my favorite stretch of this beach, where I’ve found most of my better Paleocene finds, things began to pick back up a bit. I found a nice tiny crocodile tooth tumbling in the wash, then only a few steps later I see a beautiful 1.48” Otodus partially buried in the sand! Before reaching the end of the beach I also found a large ray plate fragment and nice shark vertebra! The walk back was slow with the waves not churning up much as I’m walking back in my footsteps, I already a nice haul for the day so it didn’t bother me. It was another great day along the river, thanks for reading. Bonus picture from another Paleocene trip a couple weeks ago, the water was murky and high and I didn’t find enough for a full report but I did get a nice ray plate, Otodus and a heartbreaker!

I got on the beach a little later than I should have and missed low tide. I hiked down the beach in high tide, in my chest waders, and had to turn back because most of the beach had disappeared. Still found some good teeth! A nice crocodile tooth which was a tripmaker and my first piece of a large Meg! I've gotten smaller meg pieces but this one gave me a lot of hope for the future. It showed me that there are Megs out there. Found this piece of meg in the wire and rock dividers that separate the cliffs from the beach, apparently called Gabion baskets? Not sure. Anyway, I also saw a Snake sitting on some clay! Great day, I cant wait to go back. Maybe try a spot in VA next time.

Found these a few months back. My best teeth from 2023. Looking forward to more in 2024. Maryland finds, specifically about 15 miles north of Calvert cliffs

Hello, i am interested in bidding for this tooth. Description says that its a weirdly formed croc tooth, but i think its a Suchomimus premaxillary tooth instead. From all what i know, croc teeth are always a circle in the cross section and dont have striations. The tooth has no visible serrations, but a flat area at the back. Thats why i think its a premaxillar tooth.

I noticed the fossils of more 'modern' reptiles are not commonly shown/displayed (partly because I think they are fairly common in the U.S. and not viewed as too spectacular), so I thought we might do so here. I'd love to see your croc/alligator and turtle material, especially from various locations!

I found this gorgeous crocodile tooth along the Calvert Cliffs and it looks like it has some strange white staining on it. Rinsing it with warm soapy water doesn’t seem to do anything. Is there a good way to clean off the stains or is that just how the tooth is. Thank you!

Got a surprise day off work on Tuesday so I decided to hit the cliffs to make the most of the day off. I got to the ramp around 10am to launch my kayak and headed to a beach I hadn’t been to in a little while. The trip started slow but I found a couple nice Hemipristis teeth to start getting my hopes up. I want finding to much in the wash and the water was to murky to find anything deep so I spent some time looking through debris around some fresh falls. Lo and behold a beautiful 1.75” Thecachampsa tooth is sitting right on top of one of the falls. It dried with some strange white staining that I wasn’t able to clean off, but none the less it’s still a great tooth. Continuing on I find a heartbreaking 2.3” megalodon that was broken almost in half (at least I got the larger half). Finishing up I got a few more nice Hemis and a handful of other nice smaller teeth. All in all in was a good day along the cliffs and it sure beat working. Thanks for reading, see y’all next time.

Hello everyone. I found this tooth months ago and perhaps didn’t do enough reading at the time. I labeled it a mosasaur tooth and moved on. Now having gone through more online articles I am thinking that it is indeed a crocodile tooth. Any help would be appreciated! Found at Ramanessin Brook in New Jersey, which I believe is part of the Navesink Formation. Although several other Cretaceous formations exist there too, like the Wenonah Formation. The tooth measures approximately 5/8 of an inch long by 3/8 of an inch wide at the base. There is worn down carinae with no serrations. I’m not sure what to call the pocket at the base of the tooth but you see this in both crocodile teeth and mosasaur teeth. Seems small for a mosasaur tooth but just wanted some extra input. Thank you!

It is came from Sichuan,Shaximiao Formation,Jurassic. The seller told me that it is pliosaurs but some of my friends thought it is crocodile. I really want to know its ID.

It was discovered in the Chattahoochee River in the United States. I wonder what kind of alligator it is. Could it be Deinosuchus?

I'm CRYING! I FINALLY found a small Cretaceous crocodile dermal plate (one of my bucket list finds!) in some new Aguja matrix and I was trying to carefully clean a little bit of crud on it....AND IT BUSTED INTO 7 pieces!!!! Broken Hearted. However, I managed to "mount" it on some white clay, with all but one piece which is so small I can't find it. It looks OKAY....but it looked better before I busted it. Ah well. I FOUND A CROC DERMAL!!!

Howdy all, I've seen a lot of fossils from Alligator americanus, but none from Crocodylus americanus, yet both are present in the modern day. Did C. americanus emerge later than A. americanus or are fossils of C. americanus being labeled as A. americanus for convenience?

Howdy all, I read somewhere that Thecachampsa americana is a synonym for Crocodylus americanus, at least in reguard to thecachampsa fossils found in pleistocene deposits in Florida. Is this true?
