“…3). The occurrence of Canalispina iapygia Robles-Salcedo et al in unit 3 (see Septfontaine et al, 2019, fig. 2) evidences an upper Maastrichtian age (Robles-Salcedo et al, 2019). The coordinates of the base of the section are N 31°47' 52" and E 50° 32' 53 ".…”

A new larger benthic foraminifera is described as Broeckinella hensoni from the upper Maastrichtian Tarbur Formation of SW Iran (Zagros Zone). In comparison to the type species of the genus, Broeckinella arabica Henson, which also occurs in the Tarbur Formation, the new species has distinctly larger dimensions (e.g., size and thickness of test, chamber height). The first record of a microspheric specimen of B. arabica shows previously unrecorded annular chambers in the final test stage. Therefore, the generic diagnosis is herein emended. In the Tarbur Formation, both B. hensoni n. sp. and B. arabica occur in foraminiferal-algal wackestones. However, B. arabica occurs in a wider range of microfacies, including packstones and grainstones. It is assumed that Broeckinella originated in the Upper Cretaceous with Broeckinella neumannae Gendrot. The upper Albian Broeckinella aragonensis Peybernès is herein transferred to the porcellaneous genus Peneroplis Montfort.

“…It is followed with erosional contact by clastic deposits, and Upper Cretaceous sandy limestones containing bryozoans, and the Larger Benthic Foraminifera Orbitoides gensacicus (Leymerie) ( (Rahaghi), Orbitoides gruenbachensis Papp, and more rarely Omphalocyclus macroporus (Lamarck). These deposits can be assigned to the late Maastrichtian (Robles-Salcedo et al, 2019). Above the last sample with orbitoidids assigned to the late Maastrichtian (Ah 73), an interval of sandy marls (0.8 m to 1.0 m) follows lacking any sample data.…”

A new Dasycladale is described as Dissocladella? chahtorshiana Rashidi & Schlagintweit n. sp. from Selandian carbonates of Mount Chah Torsh, Central Iran (type locality). Other occurrence is from the Sistan Suture Zone of Eastern Iran (Selandian?, Thanetian?). The medium-sized taxon displays cylindrical to slightly claviform thalli with a relatively large main axis bearing alternating primaries of variable shape. The latter show either slowly widening towards the distal end or are club-shaped displaying very short secondaries. The morphological variability of the primaries, both typical and atypical for Dissocladella, account for some doubts on the generic assignment of the new species. Dissocladella? chahtorshiana occurs in bioclastic packstones with Cymopolia mayaense Johnson & Kaska, Acroporella cf. anceps Segonzac, Halimeda sp., and benthic foraminifera (e.g., soritiids) at its type locality.
