}A new locality of early Late Triassic age in the Richmond basin of east-central Virginia has yielded abundant remains of a diversified assemblage of small to medium-sized tetrapods that closely resembles Southern Hemisphere (Gondwanan) assemblages in the predominance of certain synapsids. Associated palynomorphs indicate an early middle Carnian age for the fossiliferous strata. The discovery suggests that previously recognized differences between tetrapod assemblages of early Late Triassic age…

Improvements in the locomotor apparatus are discernible in seven groups of archosaurs and indicate that a great adaptive radiation took place before the oldest recorded fauna dominated by archosaurs appeared.

Study of the Maleri metoposaur and its comparison with the other adequately known genera, Metoposaurus from the Keuper of Europe and ‘Eupelor' from the Upper Triassic of North America, has demonstrated the weak foundation on which metopOSaur genera are based.

A study of 49 synapomorphs in the Diapsida suggests that the lack of a quadrate-quadratojugal conch and the complete lower temporal bar are secondarily derived in the `living fossil' Sphenodon punctatus, and the tuatara is therefore much less archaic than hitherto proposed.

The postcanine morphology of A. mendozensis and the inferred masticatory mechanisms suggest opportunistic dietary habits for this species, probably omnivorous or omnivore-insectivorous habits, but not strictly herbivore.
