Abstract: 

26 species belong to 24 genera and 16 families have been described and illustrated from the Callovian Tuwaiq Mountain Limestone, Khashm Al-Qaddiyah, central Saudi Arabia. 10 of the identified species belong to scleractinian corals, 7 to brachiopods, 4 to bivalves, 4 to gastropods and one to cephalopods. Actinastraea pseudominima, Thamnasteria nicoleti, Enallocoenia crassoramosa, Collignonastraea cf. grossouvrei, Burmirhynchia jirbaensis, Pholadomya (Bucardiomya) somaliensis, Pseudomelania (Rhabdoconcha) raabi and Nautilus giganteus are believed to be recorded for the first time from the Jurassic rocks of central Arabia. The identified species have close affinity to Tethyan faunas known from parts in Asia, Africa and Europe. They indicated shoaling of the sea floor persisted throughout the deposition of the Tuwaiq Mountain Limestone, in water depth ranging from 20 to 30m. The low diversity of invertebrates in the studied section may attribute to paleoenvironmental conditions prevailed during the Callovian age as high rate of sedimentation.
