First clear evidence of Anoplotherium (Mammalia, Artiodactyla) in the Iberian Peninsula: an update on the Iberian anoplotheriines

open access: yesThe Anatomical Record, Volume 308, Issue 6, Page 1783-1800, June 2025.
Abstract Anoplotheriines (Mammalia, Artiodactyla) were enigmatic, medium‐ to large‐sized ungulates that lived in Western Europe from the late middle Eocene to the earliest Oligocene. The unusual dental and postcranial specializations of these Paleogene mammals have no equivalent in other Cenozoic or contemporaneous artiodactyls on Holarctic landmasses.

Remarks on the type locality and current status of the foraminiferal species Rzehakina epigona (Rzehak, 1895) [PDF]

open access: yes, 2001
A likely topotype locality is proposed for Rzehakina epigona. As the type specimen of Silicina epigona Rzehak, 1895 is assumed to be lost, we undertook a search for new material in the type area, Zdounky village in Moravia. A single locality provided a

Glowing Seashells: Diversity of Fossilized Coloration Patterns on Coral Reef-Associated Cone Snail (Gastropoda: Conidae) Shells from the Neogene of the Dominican Republic [PDF]

open access: yes, 2015
The biology of modern Conidae (cone snails)—which includes the hyperdiverse genus Conus—has been intensively studied, but the fossil record of the clade remains poorly understood, particularly within an evolutionary framework.

Major Shifts in Equatorial Atlantic and Pacific Calcareous Nannofossil Assemblages Across the Early Eocene Climatic Optimum (EECO; ∼53–49 Ma)

open access: yesPaleoceanography and Paleoclimatology, Volume 40, Issue 6, June 2025.
Abstract The early Eocene Climatic Optimum (EECO; ∼53–49 Ma) was the warmest sustained global warming episode of the Cenozoic, accompanied by major alterations in terrestrial and marine biota. Here we detail changes in low‐latitude calcareous nannofossil assemblages at two tropical sites in the equatorial Atlantic (ODP Site 1258) and Pacific (ODP Site ...

Sequence stratigraphy, chemostratigraphy and facies analysis of Cambrian Series 2 – Series 3 boundary strata in northwestern Scotland [PDF]

open access: yes, 2016
Globally, the Series 2 – Series 3 boundary of the Cambrian System coincides with a major carbon isotope excursion, sea-level changes and trilobite extinctions.

The Earliest Known Radiation of Pitheciine Primates

open access: yesAmerican Journal of Primatology, Volume 87, Issue 5, May 2025.
Right mandible and dentition of the holotype of Soriacebus ameghinorum (MACN Pv SC2), from the Early Miocene of Patagonia, compared with the living Cacajao calvus (FMNH 88813, cast), both representing extinct and extant morphologies of the Pitheciinae: Procumbent and styliform incisors and projecting canines represent a morphological complex for ...

Boreal waterways: An Early Cretaceous plesiosaur from Ellesmere Island, Nunavut, Canadian Arctic and its palaeobiogeography [PDF]

open access: yesActa Palaeontologica Polonica
A plesiosaur specimen collected from Ellesmere Island (Nunavut, Arctic Canada) by Danish geologist Johannes Troelsen in 1952 is described for the first time. The plesiosaur is late Berriasian to early Valanginian in age based on palynostratigraphy.

Fishes from the Upper Cretaceous Prince Creek Formation, North Slope of Alaska, and their palaeobiogeographical significance

open access: yesPapers in Palaeontology, Volume 11, Issue 3, May/June 2025.
Abstract The Upper Cretaceous Prince Creek Formation (PCF) of northern Alaska offers a unique glimpse into northern high‐latitude, non‐marine vertebrate assemblages, providing critical data on polar ecosystems during the late Campanian (c. 73 Ma).
