Thelodont scales from the Middle-Late Devonian Aztec Siltstone, southern Victoria Land, Antarctica

A new fossil agnathan, Turinia antarctica sp. nov., based on numerous isolated scales, comes from the lower fish-bearing beds of the Aztec Siltstone. Scales from moraine at Mount Suess, originally described as selachian or psammosteid heterostracan, are referred to the new species which shows close...
