Developmental palaeontology of Reptilia as revealed by histological studies


Scheyer, T M; Klein, N; Sander, P M (2010). Developmental palaeontology of Reptilia as revealed by histological studies. Seminars in Cell and Developmental Biology, 21:462-470.

Abstract

Among the fossilised ontogenetic series known for tetrapods, only more basal groups like temnospondyl amphibians have been used extensively in developmental studies, whereas reptilian and synapsid data have been largely neglected so far. However, before such ontogenetic series can be subject to study, the relative age and affiliation of putative specimens within a series has to be verified. Bone histology has a long-standing tradition as being a source of palaeobiological and growth history data in fossil amniotes and indeed, the analysis of bone microstructures still remains the most important and most reliable tool for determining the absolute ontogenetic age of fossil vertebrates. It is also the only direct way to reconstruct life histories and growth strategies for extinct animals. Herein the record of bone histology among Reptilia and its application to elucidate and expand fossilised ontogenies as a source of developmental data are reviewed.
