The last two decades or so there have witnessed a renaissance of scientific interest in the origin of tetrapods, driven by spectacular discoveries of fish-like sarcopterygians with tetrapod characters and very primitive tetrapods. This research has revolutionized our understanding of the sequence of acquisition of key tetrapod features as well as the timing and circumstances of critical events during this major evolutionary transition. The new finds have not only established the existence of an unexpected diversity of Late Devonian stem tetrapods but are also beginning to fill in a major hiatus in the fossil record, informally known as “Romer’s Gap”, during which tetrapods made the transition from a primarily aquatic to a terrestrial mode of life. The foremost expert in the study of origin and early diversification of tetrapods, Professor Jennifer A. CLACK, and a leading expert on late Paleozoic non-amniote tetrapods, Dr. Andrew R. MILNER, present here a synopsis of our current knowledge of the anatomy and diversity of Late Devonian and Carboniferous (Mississippian-Pennsylvanian) stem tetrapods. The phylogenetic relationships of many of the taxa included in this review remain unresolved, and thus the title “basal Tetrapoda” was selected faute de mieux. We are well aware that most authors would extend the tetrapod stem-group much farther into fish-like sarcopterygians such as Eusthenopteron. In the absence of suitable formal taxonomic categories, “basal Tetrapoda” is used here in a less inclusive meaning – tetrapodomorph taxa with limbs and digits that cannot be assigned to more derived clades such as Temnospondyli and Amniota or their respective proximate sister taxa.
