Abstract This study reports elasmobranch remains from two fossil-rich horizons in the earliest Danian Olching Formation at Waidach, Austria. These outer neritic assemblages complement previous fine-scale bulk-sampling of latest Maastrichtian horizons at Waidach and document a regional elasmobranch faunal turnover across the Cretaceous–Palaeogene (K–Pg) boundary. The Danian assemblages show homogeneity in species richness and are dominated by squaliforms. The fauna comprises 16 species belonging to 12 genera including several new taxa (Centrodeania rugosa gen. et sp. nov., Centrodeania annae ge ..read more

Late Ordovician and early Silurian virgianid and stricklandioid brachiopods from North Greenland: implications for a warm‐water faunal province
Wiley Online Library » Papers in Palaeontology
by Jisuo Jin, Christian M. Ø. Rasmussen, Peter M. Sheehan, David A. T. Harper
1M ago
Abstract An unusually rich and diverse suite of virgianid brachiopods, hitherto poorly known, is systematically described here for the first time from the Ordovician–Silurian boundary interval (late Katian – Aeronian) of North Greenland. The Late Ordovician virgianids comprise typical taxa of the warm-water Tcherskidium fauna (e.g. Tcherskidium tenuicostatum, Proconchidium schleyi, Holorhynchus giganteus and Deloprosopus dawesi sp. nov.). Among the early Silurian taxa, Virgiana hursti sp. nov. occurs as abundant shell beds, similar to other congeneric species in Laurentia, but has somewhat lar ..read more

Archaeichnium haughtoni: a robust burrow lining from the Ediacaran–Cambrian transition of Namibia
Wiley Online Library » Papers in Palaeontology
by Katherine A. Turk, Mikaela A. Pulsipher, Eugene Bergh, Marc Laflamme, Simon A. F. Darroch
1M ago
Abstract Following various assignments to Archaeocyatha, worm tubes, and finally incertae sedis, the enigmatic Ediacaran–Cambrian taxon Archaeichnium haughtoni has in recent years come to represent somewhat of a wastebasket taxon to which the indeterminate tapering tubular forms common across this interval are assigned. This ‘catch-all’ status has been aided in part by both suboptimal specimen photography and the temporary loss of the holotype after its second redescription in 1978. Recent rediscovery of the A. haughtoni holotype in the collections of the Iziko South African Museum in Cap ..read more

A new early water frog (Telmatobius) from the Miocene of the Bolivian Altiplano

Abstract We describe the new frog Telmatobius achachila sp. nov. from the late Middle to earliest Late Miocene of Achiri, based on a partial skeleton found at 3960 m above sealevel in the Bolivian Altiplano. This skeleton, attributed to a male adult, constitutes the first documented fossil record of the speciose living genus Telmatobius, endemic to the Andean Cordillera and the Altiplano. Phylogenetic analysis confirms the new species as being part of the crown group, and diverging both later than the T. verrucosus group and earlier than the T. bolivianus, T. marmoratus and ..read more

Macroflora from Lower Jurassic (Pliensbachian) of Hicks Creek, southern Talkeetna Mountains, south‐central Alaska
Wiley Online Library » Papers in Palaeontology
by Maria Barbacka, Artur Górecki, Christian Pott, Jadwiga Ziaja, Robert B. Blodgett, Curvin Metzler, Andrew H. Caruthers, Geethanalje Edirisooriya, Grzegorz Pacyna

Abstract A recently discovered Early Jurassic locality at Hicks Creek, Talkeetna Mountains, Alaska, yielded a macrofossil plant assemblage comprising predominantly bennettitaleans and ferns, accompanied by horsetails, seed ferns, cycads and conifers. Single species from different plant groups dominate the assemblage (e.g. Cladophlebis alata, Otozamites pterophylloides; less frequent Rhaphidopteris sp. and Pagiophyllum falcatum; sporadic Thallites sp., Klukia sp., Todites williamsonii, Coniopteris bella, Sagenopteris sp., Zamites sp., Nilssoniopteris pristis, Pseudoctenis sp., Eretmophyllum sp ..read more

Early eukaryotic microfossils of the late Palaeoproterozoic Limbunya Group, Birrindudu Basin, northern Australia
Wiley Online Library » Papers in Palaeontology

2M ago
Abstract Fine-grained, siliciclastic units of the >1642 ± 3.9 Ma late Palaeoproterozoic Limbunya Group, Birrindudu Basin host rich, well-preserved organic-walled microfossil assemblages that include members of total-group eukaryotes. These assemblages include taxa characteristic of this interval such as Tappania plana and Satka favosa, as well as less common taxa such as Gigantosphaeridium fibratum, Gigantosphaeridium floccosum, Kamolineata elongata (= Valeria elongata; new combination), and four new species. The new taxa include Limbunyasphaera operculata gen et sp. nov., the old ..read more

Redefining the Huayquerian Stage (Upper Miocene to Lower Pliocene) of the South American chronostratigraphic scale based on biostratigraphical analyses and geochronological dating

Abstract The Huayquerian Stage of the South American chronostratigraphic scheme (named for the Huayquerías del Este, Argentina) was originally based on a poorly known mammal association of six taxa from the Huayquerías Formation. We studied the geology, age and fauna of the Neogene sequence in this area, including the Huayquerías, Tunuyán and Bajada Grande formations. The sequence comprises a monotonous succession of synorogenic epiclastic sediments deposited under arid to semi-arid conditions. Zircon U–Pb dates from 10 tuffaceous levels (7.2–1.6 Ma) place deposition of the Huayquerías Formati ..read more

First Eocene–Miocene anuran fossils from Peruvian Amazonia: insights into neotropical frog evolution and diversity
Wiley Online Library » Papers in Palaeontology
by Olivier Jansen, Raúl Orencio Gómez, Antoine Fouquet, Laurent Marivaux, Rodolfo Salas‐Gismondi, Pierre‐Olivier Antoine
2M ago
Abstract Anurans are one of the most diverse vertebrate groups, particularly in Amazonia, where species richness exceeds that of anywhere else. Amazonian frogs belong to three main lineages (Hyloidea, Microhylidae and Pipidae), each of which diversified during the Cenozoic. However, due to the virtual absence of an anuran fossil record in that area, the evolutionary history of modern lineages has so far remained accessible only via molecular data. In recent decades, a series of field campaigns in Peruvian Amazonia led to the discovery of an unparalleled set of anuran bone fragments ..read more

Evidence for the evolutionary history and diversity of fossil sweetgums: leaves and associated capitate reproductive structures of Liquidambar from the Eocene of Hainan Island, South China
Wiley Online Library » Papers in Palaeontology
by Natalia P. Maslova, Tatiana M. Kodrul, Vasilisa V. Kachkina, Christa‐Charlotte Hofmann, Sheng‐Lan Xu, Xiao‐Yan Liu, Jian‐Hua Jin

Abstract Extant species of Liquidambar L. exhibit a disjunct distribution between western and eastern Asia and eastern North America to Central America, with the highest species diversity being in China. In this study, two new species of Liquidambar are described from the Eocene of Hainan Island, South China: L. hainanensis on basis of the leaf fossils, and L. ovoidea based on compressions of infructescences. The co-occurrences of L. hainanensis leaves, associated infructescences of L. ovoidea and dispersed pantoporate pollen grains have the combination of morphological fea ..read more
