This human bones was found on Azov See shore, Russia. Stratigraphic level and geological time of this find doesn't know. There are no archaeological items.

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local forum is "conditionally classified as Plegiocidaris" Guides/handbooks on Moscow Mezozoic (unfortunately mostly outdated) list 5 genera: Echinobrissus, Rhabdocidaris, Acrocidaris, Holectypus and Cidaris.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 http://www.geokniga.org/maps Some maps are outdated in terms of roads, but the geology remains more or less the same.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 described the location here:

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.

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 !!

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?

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.

I saw this Cretaceous Lamniformes tooth pop up on the auction site that shall not be named and grabbed it. It was inexpensive so it is not really much of a gamble. It was sold as Cardabiodon sp. It comes from the Cenomanian of Russia, Fedorovka Village, Tambov region. That is all the geological information i could get. I have not really studied up on Cardabiodontid teeth very much as I planned on getting one down the road. I did take a look at some papers on Cardabiodon and Dwardius yesterday, I also looked around for photos to compare with the pictures we were given of the tooth. The scale in the photos is cm. These are the only photos I have until the tooth arrives. I am far from an expert, closer to novice lol I think it MIGHT be a Dwardius tooth but that is really an uneducated guess based on limited research. I thought I would post it here and get some opinions from the knowledgeable folks here.
