摘要：Here, we report on a tetrapod footprint from the Transantarctic Basin in the far
north of Victoria Land, which marks the first record of terrestrial vertebrates for
this region. The single specimen derives from a previously unknown lithological
unit of Middle or Late Triassic age of the Beacon Supergroup in the Helliwell
Hills in the central Rennick Glacier area. It differs in both size and morphology
clearly from Middle Triassic trackway types from the upper Fremouw Formation
of the Queen Alexandra Range in southern Victoria Land, and likely represents
a primitive amniote, procolophonid or therapsid. The footprint is the
third evidence of fossil vertebrate trackways in Antarctica.
