We analyse the distribution of the potamidid genus Terebralia Swainson, 1840 in the European fossil record (middle Eocene to Miocene). Extant Terebralia contains species restricted to mangroves and mudflats, rendering it a reliable element for detecting these coastal environments in the fossil record. Our contribution summarizes the European fossil record of this taxon and highlights the presence of this genus within coastal environments in the European realm. Distribution in the Cenozoic is interpreted based on ecological preferences, dispersal modes and climatic restrictions of recent species. Maximum geographical distribution is reached during the Early and Middle Miocene with two species being present from the southernmost parts of Europe and Anatolia to the North Sea Basin and the Paratethys. During the Late Miocene, the distribution of Terebralia lignitarum (Eichwald, 1830) is patchy and limited to the South of Europe. The Messinian Salinity Crisis coupled with a changing climate caused the disappearance of Terebralia in the Mediterranean first, and then marked the end of mangrove environments in this province.

A new cranium of penguin from the Late Miocene of the Bahía Inglesa Formation (Northern Chile) is described here. Specimen SGO.PV.22245 exhibits a unique combination of characters that suggests it belongs to a new species of either Eudypula Bonaparte, 1856, Spheniscus Brisson, 1760, or more probably to a more basal taxon related to them. The specimen is notably smaller than the fossil species of Spheniscus and more similar in size to the extant Spheniscus. The fossa glandulae nasalis narrows caudally, the crista nuchalis transversa and the crista temporalis are expanded like short wings, and a short crista nuchalis sagittalis connects with the rounded and cranially projected eminentia cerebellaris. The fossa temporalis is subtriangular and deeper caudally and the cranial roof is widely expanded. All these features approach the condition to some species of Spheniscus and Eudyptula. However, because of the incompleteness of the material and the fact that it cannot be compared with some fossil species of Spheniscus only known through postcranial material, we are not able to provide a more accurate assignment.

Revision of foraminifers, algae and problematic algae of well-known late Viséan formations in the Jerada syncline in the Eastern Meseta, Azrou-Khenifra Basin in the Central Meseta and Oued Cherrat in the Western Meseta, suggests that the recognition of the chronostratigraphic units within this period lacks most of the foraminiferal markers in the Western European foraminiferal biozonations. Many taxa recorded in the Moroccan Meseta are considered as late Asbian guides in Western Europe, but in the Meseta, they are first recorded in the early Brigantian. Although some foraminiferal taxa are proposed as guides for the early Brigantian in Morocco, this substage is far more easily recognized by the algal and problematic algal assemblages. In contrast, the late Brigantian, and thus, the equivalent to the lower part of the Serpukhovian, is recognized by typical foraminifers that have been also recorded in Western Europe. Moreover, the algae do not display any significant change at this level. The unusual and unrepresentative foraminiferal assemblages recorded from the Brigantian in Morocco, suggest that most of the numerous outcrops and sections ascribed to the late Asbian in the literature should be revised because, as is demonstrated in a few cases in this study, those outcrops probably belong to younger Brigantian chronostratigraphic units.

The Mediterranean basin constitutes one of the best areas to analyse Neanderthal populations and lifestyles in South-Western Europe. In this context, new excavations conducted in the Middle Palaeolithic site of Cova del Puntal del Gat expand the information available regarding this rich region. In this study, new results are reported, including detailed studies on stratigraphy, lithic technology, anthracology, carpology, and zooarchaeology and taphonomy of macro and micromammals, with the final objective of characterizing the Neanderthals’ subsistence strategies and occupational patterns. These results are framed within a broader regional study perspective that includes MIS 5 and 4 sites. Chronostratigraphic review has enabled us to reorganize many sites that were originally included in MIS 3, towards older stages belonging to the end of MIS 4 and throughout MIS 5.

We report a new fossil-bearing locality from the “Chaotic Complex” units in the Northern Apennine Chain of the Emilia-Romagna Region (northern Italy). The material collected includes an articulated series of nine caudal vertebrae referable to a large-bodied ichthyosaur. Based on the nannofossil assemblage sampled from the matrix encasing the vertebrae, we refer the specimen to the early Aptian: this is the first accurate chronostratigraphic dating of a Cretaceous ichthyosaur from the Apennine Chain. The discovery of this new fossil-bearing locality is also significant because of the rather poor record of Aptian ichthyosaurs worldwide. Compared to the large majority of vertebrate remains from the “Chaotic Complex” units, usually represented by isolated or damaged skeletal elements, the specimen retains several vertebral elements in articulation and is associated to ichnological traces left by possibly saprophagous invertebrates, a taphonomic pattern which might indicate depositional conditions less destructive than those usually assumed for the genesis of the “Chaotic Complex’’ vertebrate fossils. The presence of both ichthyosaurs and thalattosuchians in the Aptian of Italy supports the persistence in the Western Tethys of the large-bodied pelagic reptile clades typical of the Middle and Late Jurassic along the first half of the Early Cretaceous.

Les Amynodontidae Scott & Osborn, 1883 sont une famille éteinte de Rhinocerotoidea Owen, 1845 connue depuis l’Éocène moyen jusqu’à la fin de l’Oligocène en Asie, en Amérique du Nord et en Europe. Nous présentons ici deux spécimens inédits d’Amynodontidae, un crâne et une mandibule, de Zaisanamynodon borisovi Belyaeva, 1971, datés de la fin de l’Éocène du bassin de Zaïssan (Kazakhstan) et un crâne de Metamynodon planifrons Scott & Osborn, 1887, daté du début de l’Oligocène des Big Badlands (États-Unis). Ce nouveau matériel a été inclus dans une matrice de caractères morpho-anatomiques. Elle a été complétée par le codage de l’espèce récemment décrite Amynodontopsis jiyuanensis Wang X.-Y., Wang Y.-Q., Zhang R., Zhang Z.-H., Liu & Ren, 2020 et les codages révisés de Cadurcotherium cayluxi Gervais, 1873 et Cadurcotherium minum Filhol, 1880. Nous avons réalisé une analyse cladistique basée sur cette matrice, incluant 31 taxons terminaux de Rhinocerotoidea. La nouvelle hypothèse phylogénétique proposée permet de discuter des positions phylogénétiques des spécimens étudiés au sein des Amynodontidae et de la position des Amynodontidae au sein des Rhinocerotoidea. Notre analyse cladistique clarifie la composition générique et spécifique des tribus Metamynodontini Kretzoi, 1942 et Cadurcodontini Wall, 1982 et soutient la monophylie de Zaisanamynodon Belyaeva, 1971. La dichotomie des deux tribus s’exprime notamment par la présence de plusieurs caractéristiques crâniennes telles que “l’allongement de l’incisure nasale” ou “la fosse préorbitaire bien développée” chez les Cadurcodontini. Ces spécialisations témoignent d’une adaptation de la région péri-nasale à la présence d’un proboscis. Notre étude ouvre également une discussion sur la biogéographie des Amynodontidae, leur émergence et dispersion en Asie à l’Éocène moyen puis leur colonisation de l’Amérique du Nord et de l’Europe de l’Est. Leur présence en Europe occidentale est, quant à elle, restreinte à l’Oligocène et liée à l’événement de la Grande Coupure.

Badgers belong to the genus Meles Brisson, 1762, which comprise four extant species (M. anakuma Temminck, 1844, M. leucurus (Hodgson, 1847), M. canescens Blanford, 1875, and M. meles (Linnaeus, 1758)). The genus is included in the subfamily Melinae Bonaparte, 1838, a polyphyletic group of Eurasian mustelids whose evolutionary relationships need further clarification. The evolutive relationships of the genus are complex and far from being resolved. This work aims to describe a nearly 1 Ma unpublished badger mandible from the Sierra de Quibas (Murcia) and to help clarify the evolutionary patterns of Euroasiatic badgers. To this end, we used 2D geometric morphometric techniques to measure 57 landmarks and semilandmarks in 79 first lower molars (m1) of Meles, ranging from Pleistocene to extant species. Our results show evidence for differentiating between primitive badgers and living species of Meles. The new m1 of Meles from the Quibas site is more gracile (relatively narrower and longer) than the other Eurasian extinct species, and shows that this specimen can be placed in the subspecies M. meles meles (Linnaeus, 1758). Our results also show that the denomination of M. meles atavus Kormos, 1914 as a related subspecies with a primitive morphology is morphologically supported. Therefore, we conclude that the living subspecies of badger M. meles meles was already differentiated in the south of the Iberian Peninsula at around 1 Ma, but some primitive remnant populations persisted in the north of the Iberian Peninsula, for which we recognize the subspecies M. meles atavus.

Polycotylidae Cope, 1869 is a clade of short-necked plesiosaurians that achieved a cosmopolitan distribution by the Late Cretaceous. Here, the material previously referred to Polycotylidae/Pliosauridae from the Upper Cretaceous of New Zealand is reviewed, concluding that only 2.4% and 7.7% respectively of the total plesiosaurians specimens recovered in these formations (late Campanian-early Maastrichtian Tahora Formation and Campanian-Maastrichtian Conway Formation) belong to Polycotylidae. This proportion is similar to that recorded in upper Campanian-Maastrichtian levels of the Allen, Los Alamitos and La Colonia formations, northern Patagonia (Argentina) and southernmost Chile, but contrasts with the coeval absence of polycotylids in Campanian-Santonian levels of Antarctica and central Chile. These new results improve our knowledge about the representation of Weddellian polycotylids and underline the relative scarcity of Campanian-Maastrichtian records in the Weddellia Province.
