Synopsis Formal diagnosis of Westlothiana lizziae, a new genus and species is given, to differentiate this taxon and to comply with the International Code of Zoological Nomenclature. This is the most primitive known reptile and establishes the presence in the Lower Carboniferous of a reptile fauna sufficiently ancient to have been ancestral to all later amniotes.

A new study of Solenodonsaurus janenschi, and a reconsideration of amniote origins and stegocephalian evolution
A restudy of the holotype and other known specimens of Solenodonsaurus, a Late Carboniferous relative of amniotes, suggests that this taxon did not have a tympanum. Its teeth lack labyrinthine info...
The origin and early diversification of tetrapods
TLDR
Devonian tetrapods were more fish-like than believed previously, whereas Lower Carboniferous tetrapod faunas contain early representatives of the amphibian and amniote lineages.
The importance of global parsimony and historical bias in understanding tetrapod evolution. Part I. Systematics, middle ear evolution and jaw suspension
Abstract A phylogenetic analysis based on a data matrix of 43 taxa and 155 osteological characters has produced a new hypothesis of tetrapod phylogeny that is drastically different from the
The importance of global parsimony and historical bias in understanding tetrapod evolution. Part II. Vertebral centrum, costal ventilation, and paedomorphosis
TLDR
If paedomorphosis was an important process in the origin of lissamphibians, it may have occurred earlier than previously suggested because lepospondyls can be interpreted asPaedomorphic stegocephalians.
Archerpeton anthracos from the Joggins Formation of Nova Scotia: a microsaur, not a reptile
New anatomical information, provided by reinterpretation of the pectoral girdle and exposure of previously unprepared portions of the holotype, reveals that the early tetrapod Archerpeton anthracos

TLDR
This chapter discusses their evolutionary past and then shifts focus to those species most likely to be encountered at the Ometepe and La Suerte field stations, providing in detail their diversity and natural history throughout Central America.
The oldest known tetrapod (Temnospondyli) from Germany (Early Carboniferous, Viséan)
A unique skull roof fragment of a relatively large-sized tetrapod of Viséan age from Chemnitz-Glösa, Saxony, is described. The specimen consists of three bones, an elongated supratemporal with a
Westlothiana lizziae from the Viséan of East Kirkton, West Lothian, Scotland, and the amniote stem
Westlothiana lizziae is known from the Brigantian of East Kirkton, Scotland. The skull resembles that of later amniotes in the large size of the parietal, the apparent loss of the intertemporal, and
Carboniferous tetrapod biostratigraphy, biochronology and evolutionary events
Tetrapod (amphibian and amniote) fossils of Carboniferous age are known almost exclusively from the southern part of a palaeoequatorial Euramerican province. The stratigraphic distribution of

The timing of major events in the evolutionary history of early tetrapods is discussed in the light of a new cladistic analysis. The phylogenetic implications of this are compared with those of the

TLDR
The discovery of a much earlier amniote skeleton from the Brigantian (Lower Carboniferous) of Scotland, which thus represents the earliest occurrence of amniotes in the fossil record.
