Helveticosaurus is a Triassic marine reptile from Switzerland. Long assumed to be a basal placodont, it isn't, nor does it seem to be a sauropterygian. Its short, boxy head, and long pointed teeth make us wonder what it did for a living, and while its long tail indicates that it swam via axial undulation, its robust pectoral girdle and arm and long fingers suggest that it used its forelimb in some sort of underwater flight.
