New Members vazs Posted September 6, 2022 New Members Share Posted September 6, 2022 I've become very interested in purchasing a Keichousaurus fossil. As an avid collector of ancient coins, I know how easily such things can be fabricated and altered, so I wanted to get the opinions of some enthusiasts. I just wanted to know based on the photos if you all think the fossil is genuine or not. Thank you all in advanced! Link to comment Share on other sites More sharing options...
Crazyhen Posted September 7, 2022 Share Posted September 7, 2022 This one is a typically poorly prepped Keichosaurus by acid and mechanical means. A lot of the bones were worn off. It's genuine but not of a good quality. You can compare to the unprepped "natural" forms of Keichosaurus below to tell the difference. 2 Link to comment Share on other sites More sharing options...

I really appreciate the insight! Is there anywhere you recommend looking for such specimens that are "unprepped"? Link to comment Share on other sites More sharing options...
Crazyhen Posted September 7, 2022 Share Posted September 7, 2022 Unprepped "natural forms" are relatively uncommon (only occurs when the specimen is embedded on a hard matrix and "covered" by a soft matrix). Most of the Keichosaurus found are embedded in hard matrix that manual prepping is difficult, and thus locals use acid and mechanical prepping to remove the hard matrix. It really depends on the chance of encountering a natural form in the online sale platform. Link to comment Share on other sites More sharing options...
