Ecomorphology and bone microstructure of Proterochampsia from the Chañares Formation [PDF]
Acta Palaeontologica Polonica, 2019 Proterochampsians are a South American endemic group of non-archosaurian archosauriforms with morphological characteristics recollecting Recent crocodilians, and therefore have been proposed as aquatic species. However, this has not been based on careful

A Review and Evaluation of Homology Hypotheses in Echinoderm Paleobiology
, 2023 The extraxial-axial theory (EAT) and universal elemental homology (UEH) are often portrayed as mutually exclusive hypotheses of homology within pentaradiate Echinodermata. EAT describes homology upon the echinoderm bauplan, interpreted through early post-

Considering the Case for Biodiversity Cycles: Reexamining the Evidence for Periodicity in the Fossil Record [PDF]
, 2007 Medvedev and Melott (2007) have suggested that periodicity in fossil biodiversity may be induced by cosmic rays which vary as the Solar System oscillates normal to the galactic disk.

Molecular Paleobiology of the Echinoderm Skeleton
, 2022 Molecular paleobiology provides a promising avenue to merge data from deep time, molecular biology and genomics, gaining insights into the evolutionary process at multiple levels. The echinoderm skeleton is a model for molecular paleobioloogical studies.
