摘要

This is perhaps not surprising when it is remembered that the well-known Mesozoic Napeng fauna, the exact position of which is still by no means settled, was once thought to be of Devonian age, while the Brachiopod Limestones of the Laos have, at various times, been regarded as possessing Palaeozoic, Liassic and Middle Jurassic affinities before their recent attribution to the Upper Trias.
