Anatomy, morphology and evolution of the patella in squamate lizards and tuatara (Sphenodon punctatus) [PDF]

, 2016
The patella (kneecap) is the largest and best-known of the sesamoid bones, postulated to confer biomechanical advantages including increasing joint leverage and reinforcing the tendon against compression.

ppgm: an R package for integrating neontological, palaeontological, and climate data in a phylogenetic comparative framework

Palaeontology, Volume 68, Issue 6, November/December 2025.
Abstract Understanding how changes in climate affect habitat availability for species through time is critical for macroevolutionary, ecological, and conservation research. When combined with palaeoclimate reconstructions, the fossil record provides insights into how species' geographic distributions have responded to past climate shifts, including ...

New Permo-Carboniferous geochemical data from central Thailand: implication for a volcanic arc model [PDF]

, 1991
Current ideas and models of geotectonic reconstructions of Southeast Asia are reviewed and new data on Late Carboniferous through Middle Permian tuffites and sills from central Thailand are presented in the light of the problems of Southeast Asian ...

Proteomic analysis resulting in species‐level identification of recently diverged North American arvicoline rodents

Journal of Quaternary Science, Volume 40, Issue 7, Page 1240-1251, October 2025.
ABSTRACT North American arvicoline rodents have long been considered to have high biogeographic, biochronologic, and paleoecological value. They provide relative dating of faunal assemblages when absolute dating is not possible and contribute to paleobiome characterization.

Pliensbachian–Toarcian ostracod biogeography in NW Europe: Evidence for water mass structure evolution [PDF]

, 2007
This paper examines the role played by palaeoceanographic and climatic conditions on the palaeobiogeography of the Pliensbachian–Toarcian ostracods (Early Jurassic) in the European Epicontinental Sea (EES).

Ten simple rules to follow when cleaning occurrence data in palaeobiology

Palaeontology, Volume 68, Issue 5, September/October 2025.
Abstract Large datasets of fossil occurrences, often downloaded from online community‐maintained databases, are a vital resource for understanding broad‐scale evolutionary patterns, such as how biodiversity has changed through time and space. Such datasets, however, are not infallible and must be ‘cleaned’ of inaccurate, incomplete, or duplicate data ...

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

The 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.

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

Acta 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.
