Per Christian Posted February 8, 2022 Share Posted February 8, 2022 Hello all I was offered this beauty from Sakaraha formation, Mid Jurassic (Bathonian) of Madagascar. It is ID'd as sauropod because there aren't any ornithopods known from the formation. What do people here say? It's 8 cm long . Link to comment Share on other sites More sharing options...
Troodon Posted February 8, 2022 Share Posted February 8, 2022 Very little is known or published from the Isalo IIIb formation most of which focuses on Sauropods. These claws are typically sold as Sauropod but we really do not know what they are from could also be an Ornithopod. Just because none have been described it does not mean they do not exist and are typically found in Jurassic deposit. My biggest issue with any material from Madagascar is Provenance. Cretaceous and late Jurassic exposures are close and I'm concerned if locals diggers know how to distinguish between them and then it passes through several hands before it get to a collector. Have they provided you a specific locality like Ambondromamy, Tsinjorano, and Port–Berge where this was found? Anyway nice claw, needs cleaning but be open that it might not be what its claimed.

Thank you! I'll inquire about exact location. The claw is quite ornithopod like, so it seems a bit like a gamble yes.. do you have a gut feeling on this claw whether it seems more likely it's sauropod or ornithopod?

Troodon Posted February 8, 2022 Share Posted February 8, 2022 If you like the claw acquire it. Research articles come out all of the time that might shed some light on it. I would first want feel comfortable with the provenance than the ID. No gut feeling on items from Madagascar they have very unusual critters like Razanandrongobe and little is known from the mid jurassic. 1 Link to comment Share on other sites More sharing options...

Troodon Posted February 8, 2022 Share Posted February 8, 2022 That's what I expected is the standard response. Link to comment Share on other sites More sharing options...
Per Christian Posted February 8, 2022 Author Share Posted February 8, 2022 Is it a dubious location? Link to comment Share on other sites More sharing options...
Troodon Posted February 8, 2022 Share Posted February 8, 2022 No its the standard locality used by sellers for Isalo III material but its what I said above. "Cretaceous and late Jurassic exposures are close and I'm concerned if locals diggers know how to distinguish between them and then it passes through several hands before it get to a collector" Just a concern 1 Link to comment Share on other sites More sharing options...
