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.

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.
