Abstract

New collection work in Mount Flora, Hope Bay, Antarctic Peninsula, has confirmed the presence of bivalve moulds in the Jurassic Mount Flora Formation. In contrast to a twenty-first century article claiming to report the first discovery of fossil freshwater molluscs in Antarctica, evidence of these molluscs was first reported for Antarctica more than 110 years ago by J. Gunnar Andersson. The bivalve was formally described and named some 50 years later, by Camacho, as Antediplodon esperanzaensis. The species was subsequently transferred to the genus Diplodon for unknown reasons. Here, we illustrate specimens from the same locality for the first time with photographs, considering them Unionida incertae saedis, in view of the absence of diagnostic characters. In fact, two morphotypes are present, one elongated, very similar to the nominal species A. esperanzaensis, and another one subelliptical in shape.

We would like to express our sincere gratitude to the Asociación Paleontológica Argentina for permission to reproduce Fig. 3 of Herbst and Camacho (1970), published in Ameghiniana; to the Instituto Antártico Argentino for the logistic support and Martín Sakamoto and the crew of the Esperanza Argentine Antarctic station for their help in the field work; and to Mike Reich and Simon Schneider (PalZ editors), Arthur E. Bogan and an anonymous reviewer, whose comments and suggestions greatly contributed to improve an early version of the paper.
