A new lapillopsid from Antarctica and a reappraisal of the phylogenetic relationships of early diverging stereospondyls ...
Stereospondyls underwent a global radiation in the Early Triassic, including an abundance of small-bodied taxa, which are otherwise rare throughout the Mesozoic. Lapillopsidae is one such clade and is presently known only from Australia and India. This clade’s phylogenetic position, initially interp...
