A new Palaeogene elasmobranch fauna (Tebessa region, eastern Algeria) and the importance of Algerian-Tunisian phosphates for the North African fossil record Ann. Paleontol. (IF 1.0) Pub Date : 2023-10-28 Salim Boulemia, Sylvain Adnet
During the Palaeocene-Eocene transition, the southern Tethys margin is characterized by several African phosphate deposits with many fossil teeth of elasmobranchs. Contrary to the rich Moroccan fossil record, fossil elasmobranchs from the area that includes today the Algerian-Tunisian border (e.g. Metlaoui-Gafsa-Onk Basin) have received few attentation since the last century of exploration.

The otter Lontra Gray, 1843 (Mustelidae, Lutrinae) in the late Pleistocene – early Holocene of Uruguay Ann. Paleontol. (IF 1.0) Pub Date : 2023-10-28 Aldo Manzuetti, Martín Ubilla, Washington Jones, Felipe Montenegro, Daniel Perea
Within the order Carnivora, mustelids represent the most diverse family worldwide, with a great ecomorphological diversity in terms of diet, size and locomotory adaptations. Among them, the subfamily Lutrinae corresponds to semiaquatic forms, in which the genus Lontra is included. Widely distributed at present day, this genus is represented by three species across South America (Lontra longicaudis

Microbial influence in the Messinian sedimentation: Example of Cap Bon (NE Tunisia) Ann. Paleontol. (IF 1.0) Pub Date : 2023-04-04 Jean-Paul Saint Martin, Sihem Hlel, Juliette Debrie, Nadia Ben Moktar, Simona Saint Martin, Beya Mannai-Taiech
Messinian sedimentation in Tunisia is characterized by the absence of large carbonate platforms known in many Mediterranean marginal basins. As a result, correlations are not easy to establish in order to integrate it into a general pattern of development at the regional level. However, the discovery of microbial constructions of metric scale makes it possible to precise uncertain points. Thus in the

Shurabia taewani sp. nov., is the first representative of the reculid family Geinitziidae described from the Upper Triassic of South Korea. The preservation of numerous wing venation characters on this new fossil allows for its placement in the genus Geinitzia and a deep comparison with other genera of Geinitziidae. This discovery suggests that the insect paleofauna of the Amisan Formation is rich

Hypowaagenia? bodenbenderi (Behrendsen): A rare aspidoceratid ammonite from the Tithonian of the Neuquén Basin, Argentina Ann. Paleontol. (IF 1.0) Pub Date : 2022-11-22 Horacio Parent, Günter Schweigert, Armin Scherzinger, Alberto C. Garrido
Among the ammonite collection from the Neuquén and Mendoza provinces made by G. Bodenbender, stands Aspidoceras bodenbenderi Behrendsen. This rare aspidoceratid is assigned to the lower Alternans Zone because of the associated Parodontoceras calistoides (Behrendsen), and can be most likely attributed to the recently established genus Hypowaagenia Schweigert & Schlampp.

The heteromorph ammonite genus Ammonitoceras Dumas, 1876 (Ancyloceratidae) in the lower Aptian (Lower Cretaceous) of the Les Ferres Aptian Basin (southeastern France) Ann. Paleontol. (IF 1.0) Pub Date : 2022-11-14 Stéphane Bersac, Didier Bert
Ammonitoceras Dumas, 1876 is a genus of heteromorph ammonites characterized by the presence of a peculiar ontogenetic stage in its inner whorls: the Ammonitoceras stage. But in spite of its wide paleogeographic and biostratigraphic extension throughout the Aptian (Lower Cretaceous), this genus remains poorly known. In the present work we study specimens of Ammonitoceras from the lower Aptian Deshayesites

Since its first description in 1960, the brachyuran crab genus Pleolobites was restricted to the Eocene (Ypresian) strata of Ivory Coast. Here, we report newly collected specimens that indicate its presence in the Paleocene (Thanetian) of Togo. This monotypic genus has been classified within various higher taxa, including Portunidae, Macropipidae, and Carcinidae, depending on the concurrent classification

A new stratigraphic occurrence of the taxon Pagetia (Trilobita) from the Spiti region and its biostratigraphic significance in correlation of the Wuliuan Stage (Miaolingian Series) in the Kashmir and the Spiti regions (Tethyan Himalaya), India Ann. Paleontol. (IF 1.0) Pub Date : 2021-09-08 Birendra P. Singh, Jinliang Yuan, Om. N. Bhargava, Garry Singla, Ramanpreet Kaur, Stanzin Stopden, Scott Morrison, Madhusudan Sati, Deepak Kumar, Ali Wazir
Abundant, though moderately well-preserved, specimens of Pagetia sp. are recorded along with the ptychopariid Xingrenaspis dardapurensis from a new stratigraphic level which lies above the Oryctocephalus salteri biozone in the Spiti region (Himalaya). This occurrence of Pagetia in a higher stratigraphic level (higher than the Oryctocephalus salteri biozone) from the Spiti region helps in understanding

The oldest nautiloid recorded from the Triassic Germanic Basin and the first ammonoid from the Aegean (Middle Triassic) of Poland Ann. Paleontol. (IF 1.0) Pub Date : 2021-09-06 Robert Niedźwiedzki, Dawid Surmik, Agnieszka Chećko, Karolina Paszcza, Sreepat Jain, Mariusz A. Salamon
During the Triassic in Europe, the Germanic Basin extended from England in the west to the eastern border of Poland in the east. Although cephalopods are common in some Middle Triassic (Muschelkalk) horizons, there still persists a gap in the palaeontological record of the eastern part of the Germanic Basin, notably in the lowermost parts of the Lower Muschelkalk, spanning the latest Olenekian-Aegean

Brittle stars from the upper Cenomanian of the Preafrican platform: First ophiuroid remains for the Cretaceous of Algeria Ann. Paleontol. (IF 1.0) Pub Date : 2021-09-06 Richard Štorc, Madani Benyoucef
While Late Cretaceous ophiuroids are relatively well known in Europe, these faunas have been much less studied in North Africa. With the exception of some Tunisian assemblages preliminary described at the turn of the 21st century, nothing is known about the Cretaceous brittle stars of the southwestern Tethyan margin. The present paper seeks to bring the first data about hitherto unknown ophiuroids

Tragoportax and Miotragocerus from Nagri Formation type locality, Siwalik Group, Pakistan (early Late Miocene): Taxonomic problems and hypotheses regarding their resolution Ann. Paleontol. (IF 1.0) Pub Date : 2021-09-06 Sayyed Ghyour Abbas, Muhammad Adeeb Babar, Muhammad Akbar Khan, Ibrar Hussain, Muhamamd Akhtar, Aamir Yasin, Maheen Khalid
This article focuses on some new material of currently called Miotragocerus/Tragoportax complex of species, collected from Nagri type locality, early Late Miocene (10.039 to 9.969 Ma) of the Siwalik Group of Pakistan. Along with the material description, the issues regarding the taxonomic status of Tragoportax, Miotragocerus, Sivaceros and Helicoportax are briefly discussed on the basis of preliminary

First partial cranium of Togocetus from Kpogamé (Togo) and the protocetid diversity in the Togolese phosphate basin Ann. Paleontol. (IF 1.0) Pub Date : 2021-06-11 Koffi Evenyon Kassegne, Mickaël J. Mourlam, Guillaume Guinot, Yawovi Zikpi Amoudji, Jeremy E. Martin, Kodjo Adika Togbe, Ampah Kodjo Johnson, Lionel Hautier
Earliest cetaceans (whales) originated from the early Eocene of Indo-Pakistan, but the group dispersed through most of the oceans of the planet by the late middle to late Eocene. This late Eocene global distribution indicates that important dispersal events took place during the middle Eocene (Lutetian), a globally undersampled time interval that is well documented in the Togolese phosphate series

Cenomanian (Upper Cretaceous) bivalves from the Hameimat Massifs, north of Tebessa, Algeria: Systematics, biostratigraphy, palaeoecological and taphonomical remarks Ann. Paleontol. (IF 1.0) Pub Date : 2021-06-05 Samira Mendir, Sihem Salmi-Laouar, Gamal M. El Qot, Wagih Ayoub-Hannaa, Bruno Ferré
In the eastern Saharan Atlas, particularly in the northern area of Tebessa Province (NE Algeria), the widely outcropping Cenomanian strata display a highly diversified macrofauna, among which bivalves are prominently represented. Twenty-eight bivalve species are here reported for the first time from the Cenomanian of Hameimat Massifs. Based on the stratigraphic distribution of these bivalves, five
