Abstract Eusuchia is a crocodyliform clade with rich and diverse fossil record dating back to the Mesozoic. There are several recent studies that analyse palaeodiversity over time, but none of them focuses exclusively on eusuchians. Thus, we estimated subsampled eusuchian species dynamics time not only at global scale, also by continents main crocodylian lineages (Alligatoroidea, Crocodyloidea Gavialoidea). These estimates reveal complex spatiotemporal patterns, in which two maxima can be...
Abstract We describe two new osteolaemine crocodylids from the Early and early Middle Miocene of Kenya: Kinyang mabokoensis tax. nov. (Maboko, 15 Ma) tchernovi (Karungu Loperot, 18 Ma). Additional material referable to is known Chianda Moruorot. The skull was broad dorsoventrally deep, genus can be diagnosed based on combined presence a partial overbite, subdivided fossa for lateral collateral ligament surangular, maxilla with no more than 13 alveoli. Phylogenetic analyses morphological...
The eusuchian crocodyliforms recorded in the Eocene levels of Spanish Duero Basin belong to three lineages: Planocraniidae, with species Duerosuchus piscator; Alligatoroidea, represented by several specimens genus Diplocynodon; and Crocodyloidea, which includes traditionally attributed Asiatosuchus. Asiatosuchus, established 1940 based on a middle from Mongolia, has subsequently served as wastebasket taxon for Paleogene remains belonging species, not only Asia but also European North...
The Palaeogene sedimentary successions of the Duero Basin host an important record fossil vertebrates, especially mammals and reptiles. main sites are placed at west margin (Salamanca Zamora areas) spanning from Lutetian to late Priabonian; southeast tip (Almazán Basin) mainly Bartonian in age. continued study is supplying new data that will improve chronostratigraphy correlation between western eastern regions basin. diversity phylogenetic relationships represented fauna have been revised...
Notosuchians are a crocodyliform clade with rich Gondwanan fossil record, especially in Cretaceous South American deposits. More than half of all described species come from America and, around one quarter, have been discovered the Adamantina Formation (Bauru Group, Brazil). The large amount notosuchian remains this formation, along its chronostratigraphic uncertainty, may be distorting palaeodiversity estimates. In order to analyse how these factors could biasing our interpretations,...
Abstract Allodaposuchus precedens is a basal member of Eusuchia, which was established almost century ago on set cranial and postcranial fragmentary remains from the lower Maastrichtian Vălioara, Romania. It first described type species Allodaposuchidae, recently European clade representing one nearest outgroups to Crocodylia. Although our understanding group has expanded in recent years through description new forms, review Al. needed. The detailed revision classical material including...
Duerosuchus piscator is a middle Eocene eusuchian known only from Corrales del Vino (Zamora, Spain). The species was defined based on an incomplete skull, partial lower jaws and two vertebrae single individual, several osteoderms referred to other specimens. A detailed study of these remains allows us question the attribution all same form. Just cranial are considered as indisputably attributable it; validity this being supported. present provides description amended diagnosis for piscator,...
The purpose of this application, under Article 75.5 the Code, is to set aside all type fixations for crocodyliform Allodaposuchus precedensNopcsa, 1928, and designate a neotype. series A. precedens includes specimens from Maastrichtian (Late Cretaceous) Vălioara, housed at Magyar Állami Földtani Intézet (Hungarian Geological Institute) in Budapest, Hungary. original material several cranial postcranial elements thought correspond same specimen but attribution remains as belonging one...
The fossil record of postcranial remains assigned to Allodaposuchidae is currently sparse. However, the Late Cretaceous paleontological site Lo Hueco (Cuenca, Spain), from where two new taxa allodaposuchid have been described, has yielded numerous assignable this clade. Among them, large amount pelvic and femoral material notable, providing opportunity study these elements assess their morphological similarity with other eusuchian remains. comparison extant crocodylians was accomplished...
