Tunethyris blodgetti sp. nov. from the Triassic Saharonim Formation, Makhtesh Ramon, an erosional cirque in southern Israel, is erected on the basis of a suite of 39 articulated specimens. The shells are very strongly sulciplicated, a feature that seems to be more prevalent in the Mesozoic than the Palaeozoic. The Saharonim Formation was deposited under quasi-normal, calm, relatively shallow marine conditions. Faunal constituents of the Saharonim Formation include conodonts, ostracods, foraminiferans, bivalves, cephalopods, gastropods, echinoderms and vertebrate remains that belong to the Sephardic Province and are diagnostic of the Middle Triassic series of Israel. The faunal composition and shallow depositional environment of the strata may help differentiate the Sephardic Province from the Germanic Muschelkalk and the Alpine Tethyan faunas to the north.

Menathyris wilsoni gen. et sp. nov. is described from the Limestone and Marl Member (Early Ladinian) of the Saharonim Formation (early Anisian–late Carnian), at Har Gevanim, Makhtesh Ramon, southern Israel. The Saharonim Formation represents the main transgressive phase of the Middle Triassic. The subunit, from which the shells were collected, contains the molluscs Neoschizodus laevigatus (Ziethen), Myophoriopsis cf. subundata (Schauroth), Lima cf. tellei Bittner, Pecten discites (Schlotheim), Ostrea montiscaprilis Klipstein, Pseudoplacunopsis fissistriata (Winkler), Gevanites awadi (Parnes), and the conodont Pseudofurnishius murcianus (Van den Boogaard), the last-mentioned indicative of the Fassanian (Early Ladinian).

The late Ladinian to Late Triassic succession of the Tahtalidag (upper) Nappe of the Antalya nappes was studied in the Egregindere section, north of the city of Antalya, SW Turkey. The chert bands in the central part of the section have yielded poorly to moderately preserved radiolarians documenting the Late Ladinian Muelleritortis firma and Muelleritortis cochleata radiolarian zones. Based on the Egregindere succession, a major deepening event, evidenced by radiolarian cherts, took place between the middle and late Late Ladinian. The Late Triassic thick-bedded neritic limestones represent a shallowing-upward sequence, which formed as a result of the horst-like rising of the Tahtalidag Nappe during the Late Triassic block faulting. Fifty-nine radiolarian taxa have been determined from the Upper Ladinian of the Egregindere section. One species (Muelleritortis elegans) and two subspecies (Muelleritortis firma equispinosa and Muelleritortis firma globosa) are described as new.
