ricardo Posted January 13, 2019 Share Posted January 13, 2019 It looks a Strombidae... I see deep sutures and spiral ribs on the composite mould. Probably a Harpagodes sp. TFF experts will tell you more or correct this. 2 Link to comment Share on other sites More sharing options...

abyssunder Posted January 14, 2019 Share Posted January 14, 2019 Try to find somewhere El Asa’ad, G.M.A., 1977. A Contribution to the Geology of the Aruma Formation in Central Saudi Arabia. Unpubl. Ph.D. Thesis, Mansoura University, 384 p., maybe there are precious informations regarding to the gastropods of your area. Harpagodes (which might be close to your specimen) doesn't appear in Gameil and El-Sorogy, 2015 revision, describing the gastropods of the Hajajah Member of the Aruma Formation. If the specimen was a surface find, it might be from the overlaying Linah Member of the same formation, in my thinking. Harpagodes is in the faunal list of this older (1966) document, but with a question mark. 3 " We are not separate and independent entities, but like links in a chain, and we could not by any means be what we are without those who went before us and showed us the way.
