U radu je izvršena revizija srednjojurskih terebratulidskih brahiopoda Jordanske doilne, a takodje su spisku predhodne faune dodati i novi taksoni. Sa profila Tel el Dahab, iz kelovejskih stena (Muganija formacija) odredjeni su novi taksoni terebratulida: Kutchithyris simoni sp. nov. i Trigonithyris wilsoni sp. nov, koji su ovom prilikom opisani. Takodje, po prvi put se iz Jordana pominju i tri terebratulidske vrste: Bihenithyris barringtoni, Ptyctothyris daghaniensis i Sphriganaria cardioides koje su nadjene zajedno sa Bihenithyris weiri, a koje imaju šire rasprostranjenje unutar Etiopske provincije. Kelovejsku Muganija formaciju severozapadnog Jordana čine fosilonosni krečnjački slojevi sa proslojcima laporaca koji su nataloženi na blago nagnutoj karbonatnoj rampi u plitkom i zaštićenom unutrašnjem šelfu. Brahiopodi pomenute formacije mogu se uporediti sa kelovejskim brahiopodima Arusia formacije sa Sinaja i Zohar i Matmor formacije južnog Izraela. Visok stepen endemizma proučenih terebratulida potvrdjuje izraženi endemizam koji je tokom srednje jure bio prisutan duž južne margine Tetisa (Etiopska provincija).

Middle Jurassic terebratulide brachiopods from the Jordan Valley are herein revised and new taxa are added to the previous faunal list. The Callovian rocks (Mughanniyya Formation) of the Tel el Dhahab section has allowed recognizing two new terebratulide taxa: Kutchithyris simoni sp. nov. and Trigonithyris wilsoni sp. nov, which are formally described herein. Additionally, three terebratulide species: Bihenithyris barringtoni, Ptyctothyris daghaniensis, and Sphriganaria cardioides are reported for the first time from Jordan, all of them recorded together Bihenithyris weiri, a more widespread taxa in the Ethiopian province. The Callovian Mughanniyya Formation of northwest Jordan is dominated by highly fossiliferous limestone beds intercalated with marlstones deposited on a low angle carbonate ramp in a shallow protected, inner shelf setting. Brachiopods of the Jordanian Mughanniyya Formation can be correlated with the Callovian brachiopod faunas of the Aroussiah Formation in Sinai and the Zohar and Matmor formations in southern Israel. The high degree of endemism of the terebratulide brachiopods under study here is yet another confirmation of the pronounced Middle Jurassic endemism along the southern Tethyan margin of the Ethiopian Province.
