Not another keichousaurus - sorry but need help
fossil_fun posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hello! Sorry to add another keichousaurus to the forum but I was hoping to get some help. I've always wanted one of these but have never done it because I am worried it might be fake. So, if anyone could provide input, I would be super grateful. I looked at the things to look for both in reals and fakes and nothing really stood out to me about either being real or fake. I am okay with slight restoration but would like it to be as authentic as possible of course. I cropped the picture to respect the identity of the collector and dealer but some of you may have seen this, haha. Thanks in advance forum!- 7 replies

I found this vertebra in some Aguja Formation micro matrix. It measures 4mm by 3mm. It's cretaceous in age from Brewster County, Texas. It looks very different from any fish vertebrae that I've ever found. It does seem to have a bit of damage. I'm thinking maybe reptilian. Possibly lizard? What do you guys think?

Below is a reptile tooth, from the Ypresian of the Ouled Abdoun Basin in Morocco, that I have been struggling to identify. I suspect it to be a dyrosaurid of some description, but I'm not particularly confident in that statement. The tooth has no serrations, but it does have a ridge on one side, which I attempted to capture in the final image. Thanks in advance for any proposed ID's Othniel

really cool fossil turns out to be really cool fake, but it had long puzzled scientists so it did not completely fool everybody, and may not even be an intentional attempt to deceive link for details

Fossils labeled as from East Bluff, California but not so sure if that’s correct
Guest posted a topic in Fossil ID
These were sold to me stating they came from the East Bluff area in Newport Beach, California. But research into fossils from that area comes up with late Pliocene material that doesn’t look anything like these. The serrated tooth is especially confusing. Any ideas?- 5 replies

Started going through some of my older finds and thought I’d try to identify some of them. These are all found in Gainesville, Florida creeks. First one is just a chunk of bone, not sure if it’s even identifiable. My guess is part of a scapula because it’s somewhat flat and curved. Second is a small bone, maybe a carpal of some sort? And third, I’m thinking is a partial alligator tooth. I can see a small bit of enamel left on it, but the enamel seems to have some ridges on it which is confusing.

Fake or genuine fossil?
Nothosaurus posted a topic in Is It Real? How to Recognize Fossil Fabrications
Greetings everyone. This is my first time on the form. I purchased this supposedly genuine Nothosaurus fossil. I am questioning its genuineness. I would really appreciate any input from those of you who are knowledgeable in this area. I have added photos. Thank you so much -

A customer/friend of mine has bought a nice meg tooth and a bivalve from me for his boss for Christmas. He would like to get him a fossil book for a gift now too. He says one that covers marine and land would be good. Something to spark his imagination but also to learn from. He is looking to spend £30 to £40 on it, any pointers would be good please?

From the album: Holzmaden
This is a 11 cm long pterosaur bone (maybe a flight phalanx) from the lower Jurassic from the quarry Kromer near Holzmaden. It was a very luck find as I found it on a stone, which I took with me because of another fossil. So I am very happy with this find although the preservation is not the best....

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!

Howdy everyone! I was hoping y'all could help identify or at least give a broad idea of what kind of animal this beautiful little claw could have belong to. The claw was found in Harding County, South Dakota (Hell Creek formation) and is said to likely come from a large lizard or amphibian. Any thoughts? As always, thank you guys so much! This forum is truly invaluable.

I found this in material from the Coleraine formation of Northern Minnesota, which dates between 100-90mya, which was part of the east shore of the Western Interior Seaway. So far i know it’s reptilian but I’m wondering if anyone can give me a more specific identification. The exposed part is about 2.5-3cm long.

This appears to me to be the severed head of a reptile. It is slightly deformed post mortem. Scales or osteoderms are faintly visible in a few places. There is a branched structure on the underside that looks very much like a blood vessel. There are circular shapes at the end where the head was severed from the body, suggesting a spine and torn ends of major vessels. It was found in Deuel County, South Dakota, USA. The geology of the area is basically glacial deposits. No strata or matrix evidence is possible. It measures 60 mm x 30 mm x 35 mm and weighs 80 g. Is this a reptile head, or am I suffering from pareidolia?

Keichousaurus question
bcfossilcollector posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi. I just like some opinions regarding this Keichousaurus that I’m considering aquiring. It looks good to me apart from some instability in the plate. A second plate has been attached at the bottom for extra stability. Thanks for your help! -
A tooth I recently pulled from my Woodbine honey hole keeps getting better the more I look at it. I originally thought it was just a really big crocodile tooth of the species Woodbinesuchus byersmauricei, a common find for the site. After cleaning it today, I noticed it was pretty different and am now 90% sure it's a plesiosaur tooth, perhaps from the family Leptocleididae (as opposed to Polycotylidae or Elasmosauridae) and maybe with some real scientific significance! Stay with me here... Crocodile teeth are pretty common for the site. So why do I think this isn't one? Besides being quite large for a croc, the 12 enamel ridges on this specimen vary in shape and are spaced out whereas my crocs typically exhibit tightly spaced, uniform ridges numbering in the many dozens. The ridges on the "plesiosaur" are restricted to the lingual side. My crocs typically have ridges spanning the entire circumference of the crown, though they sometimes peter out on the labial side as well. Another significant difference is in the sigmoidally curved crown which is normal in plesiosaurs and generally not seen in crocs. "Plesiosaur" (L) and Croc (R); Note the significantly different enamel ridge characteristics. "Plesiosaur" and my complete crocs. Quite large relatively speaking. It's crown is about 20 mm long and 6 mm in diameter. Sigmoidal curvature in the crown. I am less sure of the familial identification and beyond. A quick google search for Cenomanian Plesiosaurs revealed an interesting article on freshwater Kem Kem Group Plesiosaurs (https://doi.org/10.1016/j.cretres.2022.105310) from more or less the same time (Woodbine = mid Cenomanian vs. Kem Kem Group = ?Albian-Cenomanian). What initially caught my eye was Fig. 5 where a handful of similar teeth are shown: Fig. 5 from the article. Leptocleididae indet. shed teeth. These are thought to be indeterminate Leptocleididae shed teeth for features shared with my specimen. The authors rule out Polycotylidae on the basis that those teeth are usually more robust. They acknowledge that longer teeth of Polycotylidae do occur, but the striations are finer than Leptocleididae. The authors contrast their teeth (and mine) from Elasmosauridae and Cryptoclididae by stating that those families have straighter teeth with more labio-lingually compressed crowns that create a strong oval cross section. My tooth and those shown above are sub-circular/slightly oval-shaped. Another point to make is that Leptocleididae plesiosaurs are UNKNOWN from deep water environments and are instead suggested to be nearshore specialists (Woodbine is famously nearshore with its crocs, Cretodus semiplicatus, and other nearshore fauna). On the other hand, Polycotylidae, the sister taxon, is a deeper water family. Hard to show a good cross-section because a chunk of root juts out of the bottom making it look more labiolingually compressed than it really is! Implications and Significance: One extremely interesting aspect of plesiosaur ecology that is highlighted by the article is their strong presence in prehistoric freshwater ecosystems. Plesiosaur teeth of the family Leptocleididae are commonly found in the Kem Kem river systems which isn't crazy given they are thought to be nearshore specialists. The authors note that contemporaneous marine deposits have yet to yield Leptocleididae material, which makes one wonder: were they freshwater specialists unable to live in the ocean? I would've been inclined to assume they could survive both fresh and salt given my preconceived notions on plesiosaurs, but there is a lack of hard proof... Until now? If this is what I think it is... this may be the first evidence of Leptocleididae found in a marine deposit contemporaneous with the Kem Kem Group! Just the missing puzzle piece emphasized in the article. Reeling it back in- Keep in mind, a few hours ago I thought this was just a big croc tooth! Also, I don't know much of anything about plesiosaurs since I had never found such material previously. My head is spinning with all these new names. Hopefully you all can provide some clarity on this matter. @pachy-pleuro-whatnot-odon @Jared C @PaleoPastels. Feel free to tag anyone else you know who might have some knowledge on the subject!
