The extent to which mass extinctions influence body size evolution in major tetrapod clades is inadequately understood. For example, the 'Lilliput effect,' a common feature of mass extinctions, describes a temporary decrease in body sizes of survivor taxa in post-extinction faunas. However, its signature on existing patterns of body size evolution in tetrapods and the persistence of its impacts during post-extinction recoveries are virtually unknown, and rarely compared in both geologic and phylogenetic ...

SO far, workers on the Triassic dicynodonts1–3 have not been able to indicate how this group originated. However, Camp2 has enumerated twelve characters which he thought would be present in their ancestor. Eleven of these characters are found in the Eo-triassic genus Lystrosaurus4. The twelfth, concerning the presence of a cleithral groove, has been shown5 to be not significant. The so-called cleithral grooves found on the scapulæ of Triassic dicynodonts can be better interpreted as pre-spinous ...
