trilo Posted September 8, 2019 Share Posted September 8, 2019 Hi fossil forum members, its my first post here after following for a long time this great forum. It seems to me that here are a lot of experts with a lot of experience in key out specimens and that´s the reason I now would like to ask for that expertise. I got this bone 20 years ago and have not touched/preped it so far. It is from Madagascar. Any ideas are very much appreciated and will help to place it in the correct way. Thanks very much in advance Link to comment Share on other sites More sharing options...
Darktooth Posted September 8, 2019 Share Posted September 8, 2019 Welcome to the forum. Sorry that I can't ID your specimen. I am sure someone will come along who can. I like Trilo-butts and I cannot lie. Link to comment Share on other sites More sharing options...
Troodon Posted September 8, 2019 Share Posted September 8, 2019 Welcome to the forum Do you have any information on where this was found along with age and formation? Madagascar has quite a diverse dino fauna which ranges from Triassic to Cretaceous. Having said that very little is described or published so identification of any material is problematic. Like to see some straight in shots, obtuse angles make it difficult for us to see it but initially looks like a chervon or vert process.. Link to comment Share on other sites More sharing options...
trilo Posted September 9, 2019 Author Share Posted September 9, 2019 Hi and thanks Troodon for your respond, I have attached some more and hopefully better pics. If I remember right it is from the Cretaceous period and possible Sauropod. Burt I am sure you and maybe other ones know a bit more or can confirm. Any help is appreciated Link to comment Share on other sites More sharing options...

Troodon Posted September 9, 2019 Share Posted September 9, 2019 If its Cretaceous you are probably looking at the Maevarano Formation and Rapetosaurus is a Sauropod described from there and other indeterminate sauropods have been found. Canot help you with an ID since little is published. Your specimen could be a process of a large vertebra Link to comment Share on other sites More sharing options...
Haravex Posted September 9, 2019 Share Posted September 9, 2019 Based upon the shape and recently working on one I firmly believe its a chevron towards the more posterior of the tail, I'm also not 100 percent this is sauropod. Link to comment Share on other sites More sharing options...
trilo Posted September 9, 2019 Author Share Posted September 9, 2019 Thanks very much you both for your opinion. Thought it will be not easy to id it. its definately a tricky one. Maybe someone else has a guess ? Link to comment Share on other sites More sharing options...
