CT-Informed Skull Osteology of Palaeolagus haydeni (Mammalia: Lagomorpha) and Its Bearing on the Reconstruction of the Early Lagomorph Body Plan

open access: yesFrontiers in Ecology and Evolution, 2021
Lagomorpha is a clade of herbivorous mammals nested within Euarchontoglires, one of the major placental groups represented today. It comprises two extant families with markedly different body plans: the long-eared and long-limbed Leporidae (hares and ...

Using the Fossil Record to Evaluate Timetree Timescales. [PDF]

open access: yes, 2019
The fossil and geologic records provide the primary data used to established absolute timescales for timetrees. For the paleontological evaluation of proposed timetree timescales, and for node-based methods for constructing timetrees, the fossil record ...

Ecological succession of a Jurassic shallow-water ichthyosaur fall. [PDF]

open access: yes, 2014
After the discovery of whale fall communities in modern oceans, it has been hypothesized that during the Mesozoic the carcasses of marine reptiles created similar habitats supporting long-lived and specialized animal communities.

Sea surface temperature contributes to marine crocodylomorph evolution [PDF]

open access: yes, 2014
During the Mesozoic and Cenozoic, four distinct crocodylomorph lineages colonized the marine environment. They were conspicuously absent from high latitudes, which in the Mesozoic were occupied by warm-blooded ichthyosaurs and plesiosaurs.

A Review of the Paleobiology of Some Neogene Sharks and the Fossil Records of Extant Shark Species

open access: yesDiversity
In recent years, new findings and new methods (stable isotopes of oxygen, zinc, and nitrogen; 2D and 3D modeling; and geometric morphometric analyses of the teeth) have enhanced our knowledge of the Neogene shark fauna and its paleobiology.

StratPal: An R package for creating stratigraphic paleobiology modelling pipelines

open access: yesMethods in Ecology and Evolution
The fossil record is an important source of information to understand biological processes that take place over timescales not accessible to human observation or experiments. Fossil data are not a perfect reflection of past biological change, but a joint

New Records of Panthera gombaszoegensis (Kretzoi, 1938) from Europe

open access: yesQuaternary
New postcranial material of Panthera gombaszoegensis, a large pantherine felid, is analyzed from the English site of Corton (early Middle Pleistocene, possibly 0.7–0.6 mya) and the Polish site of Rogóżka Cave (0.45–0.35 mya).
