Hi everyone! Fun story behind these. I bought them when I was about 15 labeled as "Mosasaur Vertebrae". As I've gotten older and (hopefully) more experienced I'm questioning that ID after pulling them out recently. All three are from the Moroccan Phosphates. So what do you all think? I'm leaning towards croc on the third and Elasmosaur on the other two with a slight possibility of the first being really primitive whale, but I'm not sure. Any insight is greatly appreciated as always! Vertebra 1: 49.4 mm long, 52.36 mm tall, 36.54 mm and 34.8 mm wide. one centrum in concave the other is flat. Vertebra 2: 49.6 mm long, 49.23 mm tall, 49.5 mm wide. both ends concave Vertebra 3: 48 mm long, 39.9 mm tall, 34 and 32.75 mm wide. both ends slightly concave.

Introducing Hainosaurus boubker, Last of the Great Tylosaurs.
Praefectus posted a topic in Fossil News
The unnamed giant Tylosaur of the Moroccan Phosphates is revealed at last. The great and mighty Hainosaurus is a previously unrecognized macropredator present in the latest Cretaceous (Maastrichtian) of Morocco. https://www.researchgate.net/publication/365437927_First_Record_of_a_Tylosaurine_Mosasaur_from_the_Latest_Cretaceous_Phosphates_of_Morocco Authors: @Praefectus @BrennanThePaleoDude @pachy-pleuro-whatnot-odon Abstract: The latest Cretaceous Phosphates of Morocco preserve the highest biodiversity of mosasaurid squamates anywhere in the world. Intensive sampling over the past century has uncovered at least ten genera and thirteen species from the mosasaur subgroups Halisauromorpha, Plioplatecarpinae, and Mosasaurinae. Notably missing from the assemblage are members of the macropredatory Tylosaurinae. The Tylosaurinae were globally rare in the Maastrichtian and their apparent absence has been previously explained by either collecting bias, ecological preference for deeper waters, or habitat restriction to higher paleolatitudes. Here, we describe a new tylosaurine mosasaurid, Hainosaurus boubker sp. nov., based on several partial skulls and isolated teeth originating from the Couche III layer of the Sidi Chennane Phosphate quarry near Oued Zem, Morocco. It is unique amongst tylosaurine mosasaurids in possessing blade-like teeth that are laterally compressed, encircled by enamel facets, and differentiated along the dental margin. The discovery of this new taxon in the Maastrichtian of Morocco is remarkable as it represents both the youngest species of Tylosaurinae and the first occurrence in North Africa. It has been a pleasure to work on this project and I am so happy to finally see it come to a conclusion. Tremendous thank you to Boubker Chaibi (Instagram @foussilouedzem) for discovering and donating the type material. Additionally, thanks to Carlos Espinosa (Instagram @carlost_sapiens) for bringing Hainosaurus to life. Funding for this project was provided by the Association of Applied Paleontological Sciences’ Charles H. Sternberg Scholarship for vertebrate fossil research. Thank you very much the members of the AAPS.

Found this in a load of river rock delivered to my home in Omaha, Nebraska. Tried to find where the river rock came from but no luck. About the size of a large walnut. Any help would be greatly appreciated!

Species level identification obtained from facet count (3-5 prisms labially; ~5 or indistinguishable lingually). See more information in Rempert et al. 2022 - Occurrence of Mosasaurus hoffmannii Mantell, 1829 (Squamata, Mosasauridae) in the Maastrichtian Phosphates of Morocco.

Hello everybody I am a bit worried about the fossil I show. We got it many years ago and do not know much about it. As I remember it should come from Oklahoma, Permian. Reptiles. That´s it , nothing more. In my brain are some reminds name could starts with "R" for the Animal, but... What do you think? thanks for support!

Is this a Hadrosaur skull fossil??
-
I found this petrified snake/reptile head in North Carolina. I have this one and many others from my back yard. Including a petrified giant, and fingers with fingernails, perfectly preserved.. I know it's a petrified reptile from the petrification of 40 years of saltwater from the great flood. It's species is not in the internet anywhere that I can find, other than other petrified snakes, it's a one of a kind. I'm thinking it's extinct. It's very prominent for snake features and certainly a rock now. What does anyone here think? And I have many more like it. There are these and many others... You can see the neck bone, the black jugular vein, then the arterial iron oxide- Rich returning blood and that's what petrifies to gold. And they are also other species not alive today to our earthly knowledge.... Thoughts?

Going through my fossils collected over the years and found this small complete bone. It was found in the Morrin Bridge area, Red Deer Badlands. It is a beautiful little bone but I have no idea what if belongs to. Would be Cretaceous age. Found it in the same layer within five feet or so of some carnivore dinosaur teeth, a few hadrosaur teeth, etc. I think it was an area where the bones, teeth, etc. were washed into originally and then fossilized. The bone is 2 1/4 inches or 5.7 cm in length. Any ideas?

Hi all. As per request on my last post about the dinosaur eggs. Here is my fossil skeleton inside its matrix from Jiangxi, China. Bought it cheap, no clue what it is or what it could be. I can clearly see a skull, and what appears to be a claw or a hand. Nothing to see on the other side, I assume the rest of the skeleton is inside the matrix. Any help wil be appreciated, but I have let alot of knowledgable people look at it and no one was able to give me anything clear.

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.

Hi, I’ve recently been searching through some sifted gravel from a creek. I’ve been looking for microfossils, which I’ve had plenty of luck finding. All sorts of marine Cretaceous invertebrate micros are abundant in the creek gravel, as well as the occasional micro shark/fish tooth, scale, and bone fragment. I encountered a tooth that stood out from anything I’ve found so far. It has a conical shape, and is recurved. Something about this tooth seems very reptile-like. Almost looks like a tiny version of a crocodile or mosasaur tooth. The tooth measures 1 millimeter in length. I tried searching the internet for something similar, and have been unable to find something like this. The closest thing that I found was teeth from a jaw of a Coniasaurus that was found in North Texas. Here is the tooth that I found. It’s 1 millimeter from base to tip. The creek is located in Central Texas close to Austin, and passes through sediments spanning the whole Cretaceous geological column of Texas. From the Glen Rose Limestone to the Navarro Group. (~110-66 myrs). What do y’all think of this little tooth. Could it be from a small reptile like Coniasaurus and other dolichosaurs?

Hello all, I recently purchased this fragment of a limb bone of a reptile, which was labeled 'unidentified.' I was wondering if it would be possible to find out what it is, as it is really minuscule. Fossil Info: The fossil is 1.2cm long. According to the seller, it is from the Lower Permian, from the Leonardian Series. It was found in Lawton, Oklahoma, and the formation is the Arbuckle Group. I don't know if this is enough to go on since because of the small size. Thanks!

First of all - sorry for bad and rude language)) So, I need some help with identification of this teeth. All was found in Russia, Trans-Urals region, in a few different rivers: Belyakova, Sugatka and Derney. There must be Eocene period, probably lutet or barton layer, but I can't be sure, because there is no bedrock, only fossils that river stream brings. Sometimes me and other people found there more old fossils, back to cretaceous even. I showed this photo to few reptile specialists from Saint Petersburg, but they sure that is no crocodile teeth, and insist that is a fish teeth. But i have fish teeth from this region, and they looks different. There we can found Palaeocybium, Scomberomorus, Eutrichiurides and even Sphyraenodus species teeth, and all they looks like different to this teeth. So, what is it? Some new fish species, crocodile of some another reptile?

Seller said this was probably a reptile toe bone. I was just curious to know if any more info could be gleaned from it? Measurements in imperial. Thanks!

I've never seriously done paleoart before. I have been wanting to try my hand at it for years but passed on it for one reason or another. Recently I fell in love with looking at fossils of keichousaurus. I also love lizards. So I decided yesterday to just do it. So here are my results. If I messed up on the anatomy in any way, please don't hesitate to let me know.

Hi y'all, I was thinking again about some Permian reptile teeth, I've seen them referred to online as 'parareptile,' but would like collective and/or professional insight. They are pretty distinctive, with a smooth labial face, and a striated lingual face. These are all from Waurika, OK (Wellington fm, Lower Permian). I have several examples, but they're not much different from these two. @jdp @dinodigger 3.5 mm tall: 2 mm tall: They vaguely remind me of a Caseid tooth, which has the same character of the striations/no striations (or I at least think this one is Caseid...). ^ Reisz (2019)

I found this skull in our field next to our house last week. It was being pushed up from the ground. The photo shows the front R side of the face w/ clear jawline, R eye socket & R side of a crest. I would like ID help, please. We are 1/2 hour south of the WI border. It was near a fossilized, partially opened egg & the limestone-encrusted skull of a juvenile lizard, among other fossils. There are volcanic rocks nearby & we believe that the interstate Rock River was considerably larger, covering our property & bringing those things south to IL.

Found this on Jones Island, SC. Appears to be an Alligator tooth without the root. Anyone have any thoughts?

Hi I'm New here & New To Fossil hunting. I'm not sure if I have found any fossils yet but I have 2 piece I would like to get some opinions on if they are indeed fossils. FYI I live in Macon Georgia. Both of these to me look like part of a reptile of some sorts head. I would really appreciate it anything anyone could tell me even if it's that it's just a plain rock as my husband says. Thank you so much for your time.

Here is a tail of a marine reptile from the Triassic period. It was found at Fuyuan, Yunnan Province of China, at the same strata with Keichosaurus. Does it look like the tail of Yungguisaurus liae or Placodus inexpectatus? It is 56cm in length.

I don’t believe it’s a dugong fossil as IIRC they don’t have hollow marrow areas. It was found away from the beach but around shells, the peace river formation isn’t stratified either way. The last picture may be a separate all together but was found in this cluster of bone, it looks like turtle shell I have seen. It’s on a napkin for scale but the large portion is about the length of my pinky. The shell object is about the size of a nickel. Because of the shell piece found within the bone cluster I’m imagining it could be a turtle humorous

Hey all, Just got these teeth and was wondering if you guys can ID a species to them? Here are the deets… Age: Late Cretaceous. Locality:- Fluvial sandstone deposits, Kem Kem Formation. West of Hamada du Guir. Errachidia Province. MOROCCO. They were labelled as coloborhynchus moroccensis but I thought the coloborhynchus was only found in UK.I’m not really familiar with Moroccan locality to this detail other than the “Kem Kem beds” so maybe my locality provided narrows the ID possibilities? they sort of look like sirrocopteryx/ coloborhynchus teeth but based on older pterosaur ID threads, would it be safer to label these as ornithocheirid indet? Thanks for the help in advance!

Dinosaur, Reptile, and Amber Collection UPDATE: Shelf #3!
Mousehead posted a topic in Member Collections
Things are getting pretty serious over in The Fossil Zone, so I cleared off a few books and replaced them with fossils. Who needs to read, anyway? Feel free to ask questions about particular pieces. Whole collection: The turtle skull is real, but the surrounding matrix has been stained by the preparator for better visibility. Some here might recognize the new claw that arrived broken in the mail There is a Vinctifer comptoni fish on the back right, along with a negative Grallator footprint, which I can't seem to find a good way to display. New additions here include a croc/turtle egg in-matrix, a Campo del Cielo meteorite, and a few various claws. There's also a piece of the Roman Colosseum, whose origin story I should not divulge. A complete Psittacosaurus foot joins the family. To its immediate left is a Triceratops frill spike. My best-prepared fossil here is the Ichthyosaur rib plate on the right – just incredible work. The little Knightia in the front reminds me every day I need to get a really good fish fossil soon. Amber Time! My favorite time. Rarer inclusions are a mushroom, pill pug, a gigantic damselfly, triple crane flies, a large millipede, caterpillar, a bloated tick/mite, moth with perfect wings, and a small lizard claw. More amber! S-shaped Centipede, multiple termites, a gecko tail, a big fuzzy bee (middle center), and my favorite... ...the back half of a lizard stuck to a leaf on the bottom right. Nice view of that killer centipede here as well! I'm gonna need a new shelf soon, but space is limited here in this tiny NYC studio apartment. Thanks for looking, friends!

Hello, I am going to purchase this lot that is from Richard's Spur Quarry and I was wondering if anyone on here knows how to ID fossils better than me. I've been looking at pictures all day but can't seem to confidently ID anything. I know most of these are probably Captorhinus, but are there any in this lot that look like a different species or a synapsid such as Varanops? Been searching for synapsid fossils forever and I really hope one of these is from a synapsid. There's 3 claws, 3 vertebrate, and 4 jaw sections. Don't be afraid to hurt my feelings if they all are Captorhinus, I think they're super cool too!
