Paleorunner Posted August 22, 2021 Share Posted August 22, 2021 (edited) Hi, I just saw these articles, and I wanted to make sure they are real. The vertebrae of Onchosaurus seem correct, but I am concerned about Otodus' teeth, and that of Mosasaur. Mosasaur 2.2 ctms.(Just the tooth ). and Otodus 5 ctms.

Ludwigia Posted August 22, 2021 Share Posted August 22, 2021 They are both ok in my opinion. It would be a waste of time for anyone to falsify such common fossils. 1 Greetings from the Lake of Constance. Roger http://www.steinkern.de/ Link to comment Share on other sites More sharing options...

In future, a vernier or ruler are better for us to see size. I have no idea how big that coin is, much like you'd have no idea how big my country's 10c or 50c piece is From other O. obliquus teeth I've seen they look small-medium but at the medium end of the scale. That's not a criticism, they're a nice shark to add to any collection and not expensive in the size you're looking at. I have them ranging from 23mm to 87mm (slant height). But they do look in reasonably good condition apart from the broken tip and cusplet missing (unbelievably common). On both the top left and bottom right tooth I can see a crack going through the bottom of the crown into the root (top left is more obvious). Has that section broken off and been repaired? Hard to tell without seeing the labial side or better yet, handling them. Apart from that, I agree with @Ludwigia, they're are too common to fake. Restore, yes (often the restoration to the root is terrible) 1 Link to comment Share on other sites More sharing options...
Gareth_ Posted August 22, 2021 Share Posted August 22, 2021 These are on a local buy/sell page. Personally, these examples would never get close to being put into my collection. They are being sold as restored (hence the arrows) 1 Link to comment Share on other sites More sharing options...

The photos are those that the seller has, I was only worried that they were fasos, that is why I did not include the size in centimeters. Mosasaur 2.2 ctms.(Just the tooth ). and Otodus 5 ctms. Thank you very much for the information. 2 minutes ago, Gareth_ said: These are on a local buy/sell page. Personally, these examples would never get close to being put into my collection.

Ah all good then.... it is frustrating when a seller uses a coin, it's hard to get a true idea of size especially when it's a fossil you really want! 50mm, pretty much exactly where I assumed they'd be Have you got any other teeth from the Otodontidae family? Just being nosey, it's a family of sharks I have quite a few fossils from! Link to comment Share on other sites More sharing options...
