Keichousaurus or an impostor
Yan11 posted a topic in Is It Real? How to Recognize Fossil Fabrications
Hi, In 2013 I bought a keichosaurus fossil from online , and since then I haven't thought much of it, after me and my mum and dad moved to a new apartment the fossil got somewhat forgotten, but today I tried inspecting it. I read some of the treads here but even with this I can't decide if mine is a real or a fake one. From what I have gathered there aren't many outright fakes, but more so real ones that are enhanced. I will be glad to hear your opinion on the pictures (sorry for the poor quality but I had to use my phone). Any response will be very much appreciated. Best regards to everybody.

Hi all, I was recently offered this tooth from late Cretaceous of Orensburg, Russia. Most likely Gaisky City District. I can't figure out if it's a Polycotylid plesiosaur or Pterosaur tooth. The overall shape is closer to pterosaur than plesiosaur. However, I am not aware of pterosaur having wrinkling like that, nor do I know of pterosaur teeth being found there. What are your thoughts on this? Thank you.

The quarry Kromer near Holzmaden did open two weeks ago (it was closed during winter). So last Saturday I was there the first time this year and I have to say that I am kinda satisfied with my finds! I found several marine reptile teeth, some mainly incomplete bones and a fish with much potential. In this topic I want to show how I prep/prepped a plate on which originally two Ichthyosaur verts were visible. The verts are all about 4 cm big. Here is a picture of the unprepped plate: (I have the other parts...) The prep work is very difficult because the stone is extremely hard. So I have to use my air pen to remove the stone directly above the verts and then I remove the remaining thin layer with my sandblaster with about 6 bar which is probably too much for the bones but otherwise I wouldnt do any progress ... This is the current situation: Until now I prepped about 4 hours and now you see that there are even more vertebrae on the plate At least 3 and a half.... And here is the one which wasnt visible at first. I damaged it a bit but I think its not too bad. Hopefully the stone is a bit softer around this one: I think I have to work many hours on it so wish me luck @LiamL

A 3.5 cm long Nothosaur vertebra from a triassic "Bonebed" in a quarry in southern Germany (Baden-Württemberg). Two more pictures: -
From the album: Holzmaden
These are four Ichthyosaur paddle bones from the lower Jurassic from the quarry Kromer near Holzmaden. The prep was very difficult because the stone was kinda hard. I gave it up several times but now its finally finished. I hitted the bones a few times so its not the nicest piece. Maybe I will try to prep it from the other side one day. Some more pictures: -

These are four Ichthyosaur paddle bones and another Ichthyosaur bone from the lower Jurassic from the quarry Kromer near Holzmaden. The Ichthyosaur paddle bones are about 5 cm big so not too small. There are also a lot of belemnites on the plate. Because of them the prep work was kinda time intensive. It took about six hours to reveal everything. Here are some more pictures: -

Here is a little (about 1 cm long) Ichthyosaur tooth from the lower Jurassic from the quarry Kromer near Holzmaden (Germany). -
Here is a piece with four paddle bones and another bone from a rather big Ichthyosaur. I found it about 2 weeks ago in the quarry Kromer near Holzmaden (Lower Jurassic) and finished the prep today. Overall I spent about 6 hours to prep this one. Especially because of the belemnites. The paddle bones are about 5 cm long. Sadly I forgot to take a picture of the unprepped stone but you could only see the cross sections of the bones on both. But here are some pictures of the progress: Finished: And some detailed pictures: I used air scribes and air abrasion to prep it.

Last Sunday I was able to find a piece with some jaw bones and teeth of an Ichthyosaur in the quarry Kromer near Holzmaden. I was very pleased with that find because the situation in the quarry is not the best. There is only a kinda small pile of stones where you are allowed to search (and where you can find marine reptile fossils, in the other regions of the quarry its very unlikely to find a bone or a teeth of a marine reptile). And this pile consists at the moment only out of very small rocks because they were laying until the beginning of the year there. So many collectors already searched there. And it's very likely that they don't get new material in this summer... Here is a bad picture of the quarry: And here are some pictures of the jaw bone with the teeth: The prep work took about 5 hours. It's a pity that I lost that missing part in the quarry. I searched about 1 hour for it but couldn't find it. But at that time I didn't know that its a jaw bone (no teeth were visible). Now about 65 small Ichthyosaur teeth are visible. They are from a very small Ichthyosaur, maybe even from a juvenile!

This seems to be a kinda rare find because maybe these are plesiosaur bones. Plesiosaur is the rarest marine reptile in the area of Holzmaden so I am pretty happy with this find On the plate are two ribs, a phalange and an interclavicle. But I am far away from being with the ID although I already showed it too some local experts. Its from the quarry Kromer near Holzmaden (Lower Jurassic, Posidonia Shale). Unprepped: Some more pictures of the prepped specimen: -

I wasnt very active recently so sorry for that. But the last weeks I was several times hunting for fossils in the quarry Kromer in Holzmaden (Germany) and in this thread I want to show you some things I found there. As some of you know may know I am mainly interested in marine reptile fossils so most of the finds are marine reptile bones and teeth ... So firstly some teeth. I actually found a lot of them but these are the best ones I found this year: A 2 cm long Steneosaurus tooth (crocodile): Another Steneosaur tooth with a length of 1,8 cm: And the last 1.2 Steneosaur tooth: I also found some Ichthyosaur teeth. Here is one of the nicest from this year: Besides of several teeth I also found some bones. Ichthyosaur bones are the most common type of bones there so I found mainly Ichthyosaur material. Especially I found many ribs but they are mostly not prepped yet. Here is just one little example: Its about 10 cm long. I didnt found many vertebrae this year but here is a pretty neat one with a length of about 3.5 cm: A bit rarer is this little Steneosaur (crocodile) vert: I am really happy that I can say that I found some pterosaur material this year. As these are marine deposits you may can imagine that pterosaur bones and teeth are very very rare. Here is a little 6 cm long and very worn pterosaur bone: Another pterosaur bone: This one is about 11 cm long. I didnt saw that one in the quarry Kromer but I took the stone with me because of a tooth on the other side of the stone so I was very pleased as I turned the stone around at home The next one is probably my favourite find of the year until now: These are also pterosaur bones (the big one might be a humerus?) Some more pictures of the same piece: And last but not least this find: I am actually not sure what it is. Might be pterosaur bone too ( maybe a Scapula?) or another possibility would be a bone from the skull but its kinda difficult to determine isolated bones ... Still many bones and teeth to prep and the year is still young so lets see what I can find/reveal! I hope you like some of my finds and thanks for watching

This is an isolated, unidentified bone from the posidonia shale from the quarry Kromer near Holzmaden. Its very difficult to determine these isolated bones but it might be a part of a skull bone of a marine reptile ... Another picture: -

Hello, I found this tooth of a marine reptile 2 years ago in the Bathonian ( jurassic ) deposits of Thin le moutier in France. Is there any one who could give me an idea of what kind of reptile it might be? the tooth is 3mm long Thx, Natalie
