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 ...

Late Maastrichtian carbon isotope stratigraphy and cyclostratigraphy of the Newfoundland Margin (Site U1403, IODP Expedition 342) [PDF]

, 2018
Earth’s climate during the Maastrichtian (latest Cretaceous) was punctuated by brief warming and cooling episodes, accompanied by perturbations of the global carbon cycle.

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.

Late Pliocene calcareous nannofossil paleobiogeography of the Pacific Ocean: evidence for glaciation at 2.75 Ma

Revista Mexicana de Ciencias Geológicas, 2018
Calcareous nannofossil assemblages from land sections of the Japanese Islands and DSDP Holes in the equatorial to high latitude regions of the Pacific Ocean were analyzed in an effort to reconstruct their late Pliocene paleobiogeography.

The present-day Mediterranean brachiopod fauna: diversity, life habits, biogeography and paleobiogeography

Scientia Marina, 2004
The present-day brachiopods from the Mediterranean Sea were thoroughly described by nineteenth-century workers, to the extent that Logan´s revision in 1979 listed the same 11 species as Davidson, almost 100 years earlier.

Multicostate zeillerids (Brachiopoda, Terebratulida) from the Lower Jurassic of the Eastern Subbetic (SE Spain) and their use in correlation and paleobiogeography [PDF]

, 2012
The Lower Jurassic multicostate zeillerids of the Subbetic Domain are described here for the first time. A new species (Fimbriothyris? dubari) is erected, and the affinities of the remaining three species are discussed.

The evolution of reproduction in Ediacaran–Cambrian metazoans

Biological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

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 ...
