benthic foraminifera (LBF) that are common in the Cretaceous (especially mid-Cretaceous) neritic carbonate successions of Neotethys. They are encountered in suitable rocks in a broad belt centred around Central America, the Mediterranean region, the Middle East, and the Himalayas. To improve their stratigraphic utility, the identities and distribution of 15 species are critically reviewed based on published records, these taxa having at least possible occurrences in Cenomanian strata. It is shown that misidentifications have erroneously overextended the ranges of some taxa. However, there are indeed species that have long ranges, suggesting some nezzazatoids form part of a group of environmentally tolerant LBF that were able to recover from palaeoceanographic events such as widespread anoxia or sea-level change. Some of these taxa have short ranges within the Cenomanian that mark them out as potential species to be used, alongside species from other LBF groups, in the development of a biozonation/bioevent scheme for Cenomanian LBF. As with almost all mid-Cretaceous LBF, work on taxonomy/identity of nezzazatoids is an ongoing task requiring access to pristine material, including topotypes.

Abstract. This article presents a description of the shell injuries in the Early Devonian brachiopods Lanceomyonia borealiformis (Siemiradzki, 1906) from western Ukraine. Approximately eight percent of the shells (8 out of 101 specimens) exhibit shell injuries, which are classified into three morphological types: (a) rounded and ellipsoidal pits, measuring approximately 2-5 mm in diameter, located on the anterior margin and lateral slopes of the valves; (b) longitudinal, sublongitudinal, and transversal thin straight or sinuous furrows, measuring approximately 5-6 mm long and 0.5-1.5 mm wide; (c) irregularly shaped concave zones on the lateral area of the valve. The majority of the shell injuries can likely be attributed to evidence of unsuccessful predator attacks and traces of an attachment point of an epizoan organism. The potential agents responsible for the predatory injuries include cephalopods, arthropods and fishes. The frequency of injured shells among the studied brachiopods is within the range observed in other Palaeozoic-aged brachiopod assemblages.

Abstract. The new anomuran microcoprolite Favreina babai isp. nov. is described from the Late Cretaceous La Canadilla Formation of the Southern Iberian range. Within the ichnogenus Favreina, the new ichnospecies is characterized as rod-shaped bodies with numerous (> 100) laterally grouped longitudinal canals of rounded transverse sections within the symmetry plane. The high number of these canals represents an unique feature within the (Late) Cretaceous record. The new microcoprolite occurs in wackestones with miliolids (among Vidalina hispanica Schlumberger) and ostracods of shallow-water carbonates ascribed to a near-coastal facies.

Abstract. The larger benthic foraminifera Novalesia producta (Magniez) is a common constituent in the faunal assemblages of inner platform wackestone-packstone microfacies of the Aptian Taft Formation, Central Iran. The abundant specimens observed in thin-sections allow a detailed morphological and biometrical analysis of the taxon that extends the known data.

Abstract. Persiconus sarvaki Yazdi-Moghadam & Schlagintweit represents one of the latest (perhaps the latest) orbitolinids that became extinct before the Cenomanian-Turonian boundary faunal turnover. P. sarvaki has an apparently endemic distribution with a restriction to middle-late Cenomanian carbonate platforms of the former Arabian Plate margin. It is herein described from a section of the Sarvak Formation located in the Izeh Zone of SW Iran where it occurs in inner platform foraminiferal wackestones assigned to the early late Cenomanian. Details on the microfacies and the biostratigraphy of the section that includes the Cenomanian-Turonian boundary are provided. The new observations on P. sarvaki highlight the presence of two different types of embryos (thick-walled, simple and thin epidermis with partitions, complex). The same phenomenon is already known from the Eocene Cushmania americana (Cushman). This aspect is discussed in more detail in view of the current classification of the Orbitolinidae; respectively its subfamilies. In addition, the previously unknown microspheric form of P. sarvaki is recorded, as well as occasional test infestation by the foraminifer Tauchella endolithica Cherchi & Schroeder.
