I purchased some shark teeth recently, all or most of which appear to be sand tigers, from Russia and am hoping some folks on here might be able to help me identify them. The information from the seller, who is in Russia but didn't collect these himself, is that these are Cretaceous teeth found in chalk deposits on the banks of the Don River, near Kalach-on-Don, Volgograd region, Russia. He doesn't have any more info or know the exact geologic layer. I haven't been able to find much information from searching online, but using the app Rockd, it does appear that the geology in the a

After a few conversations with forum members I thought it would be useful to share some Russian papers which have probably never been translated into English, thus are not known (at least in detail) internationally. I picked 5 of the best Russian-only articles I had found which are NOT limited to local aspects and descriptions (there are quite of few of this kind) but suit any person interested in marine reptiles and give some general knowledge on the subject. The authors are our most prominent specialists. Translation into English or any other language can be made with https://translate.googl

Hi all! I was finally able to visit the Volga site thanks to a water level/ good weather window. The journey was mostly a success, I got a better understanding of the site, used new means of transportation and examined more of the shoreline. Among the finds were two dozens of marine reptile verts and bone fragments and LOTS of ammonites and other mollusks. Unfortunately the river level was not low enough, 1m higher than during my 1st trip, 0,5m lower than in the 2nd. But it was at least possible to walk the shore. There's still a lot more to do, but now I have a pretty clear idea how to m

Russian ichthyosaur (Undorosaurus) partial jaw and associated teeth
bthemoose posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, I'm considering this partial ichthyosaur jaw with 5 teeth (3 in a natural position and 2 others that have been displaced--one is on top and one is on the backside) from Jurassic (Tithonian) deposits in Tartarstan, Russia. The seller, who is also the finder/preparer, has identified this as Undorosaurus and noted that there is repair to the last tooth at the end, which broke and has been glued back together, and some holes that he filled in on that tooth--these are shown in the second photo with the red line (repaired break) and circles (filled in holes), as drawn by seller--but -
My Jurassic Park now heads across the pond to England and Germany. Dinosaur material from these countries is not common like North America and in fact very difficult to obtain. Theropod material is extremely rare and most remains are fragments. Most of my material from England comes from the coast of two areas The Isle of Wight and East Sussex. Material from these area comprises the Wealden Super Group (Hasting+Wealden+Weld Clay) and is early Cretaceous from the Valanginian to Barremian Stage (140-125mya).

Russian Heteromorph Ammonite
Charlotte787 posted a topic in Is It Real? How to Recognize Fossil Fabrications
I was considering buying this heteromorph ammonite from an online dealer and was just wondering if it looks authentic. Any advice would be much appreciated! -
Hello Dear Friends! This is my first topic on this forum. Hooray! I work in museum and sometimes go on the Kaliningrad beach of Baltic sea and search some fossils. I'am not paleontologist and i need help to definition of them. THe last time i found some algae but i'am not sure. Place was in a few meters from cliff on beach. p.s. can i add my other find in this topic or should create new?

I have a few unknowns from the Cenomanian of Russia that I am starting to get around to photographing and identifying. I am practicing with my actual camera instead of my phone so the pics are just ok but will get better lol The first one is from near Fedoravka Tambov Region of Russia. This one is about 13 mm or so. I think the ID when purchased was Cretoxyrhina but I do not know how accurate that is. I thought perhaps Cretalamna or maybe Dwardius or something completely different. I just do not know. It is a really striking tooth though and I would like to get some idea of wh

Pseudomegachasma and a few other Melovatka Formation shark teeth
fossilsonwheels posted a topic in Fossil ID
I recently acquired quite a few teeth from the Saratov region of Russia. Melovatka Formation. I have a few that I can use some ID help with. I will work on getting better pics but for now this is what I have. This is a formation from which Pseudomegachasma teeth were described and I believe I may have found 1-3 teeth that fit for that species. I spent a great deal of time under the scope with these teeth and comparing them to those described. I will eventually send pictures to Dr. Shimada when I have better quality pics. The teeth are all 4-5 mm. The first tooth is th -

What do you think it is? The definition I got on the local forum is "conditionally classified as Plegiocidaris" Guides/handbooks on Moscow Mezozoic (unfortunately mostly outdated) list 5 genera: Echinobrissus, Rhabdocidaris, Acrocidaris, Holectypus and Cidaris. For this and neighboring stratigraphic zones Echinobrissus and Rhabdocidaris only, mainly the latter. Both are defined by spines, sometimes isolated plates

Hello, Found this great site today that has nice geological maps for many Eastern European countries, plus some more. http://www.geokniga.org/maps Some maps are outdated in terms of roads, but the geology remains more or less the same. Zoom in and out using +,- on your left. If someone not familiar is interested in those areas, use this site to convert Cyrillic to latin, then translate. https://www.lexilogos.com/keyboard/russian.htm The legends on the maps though are international and recognized by colour.

Quite a rare little Russian tooth but a bit battered. Sold as from the Itat formation in Siberia. 8mm. Anyone know if it is Kileskus? Thanks

Hi all, this is not actual news as it happened in 2002, but the footage of excavation process and participants' memories became available only recently. I hope it will be interesting for everybody who is into marine Mezozoic and field paleontology in general. The species: https://en.wikipedia.org/wiki/Luskhan Excavation video: Participants' memories: Set subtitles to automatic translation, its 70% correct:) There are some weirdo mistakes, but overall comprehensible Assembled skeleton on display: I descr

Real quick, I found this Russian illaenus online, does anyone know what species it is? The seller doesn't say. Also if any of you experts think you could roughly estimate the restoration on the piece (unlikely, I know) that would be helpful too. There's a patch on the pygidium that looks restored to me but the rest looks pretty good to my eye. Thanks in advance.

This tooth was originally labelled as an Cardabiodon sp., but both dimensions and general crown's features led me to buy it due to curiosity (also was really cheap). The crown is higher than the root. The cutting edges bear no serrations. There're traces of secondary lateral cusplets. The lingual face of the root seems to have a rounded lingual foramen on the enlarged torus. The tooth, probably a lamniform, was collected near Fedorovka village, Tambov region, Russia and goes back to the Cenonian epoch (Cretaceous). Any guess?

Sold as Cretalamna, it is from the Tambov Region of Russian. Cenomanian. I found this to be an interesting tooth though I am not convinced the ID is accurate. @Chase_E has a gallery of teeth from this region and a couple of other locations from Cenomanian Russia. Using those posts as a guide, I believe the tooth may be a Cretoxyrhina, perhaps C. vraconensis. I see quite a bit of similarity with a couple of Chases teeth but I am using one as comparison in this post. I could be, and probably am, wrong about that assessment lol Any input is welcomed !!

Please help us identify the find. This was found in the sand, on the surface. On a river. It reminds me of the seed of a plant.
