Summary: | FIGURE 1. Geographic distribution (solid black dots) of members of the genus Pycnolepas; note the disjunct occurrences of early(?) Aptian and middle Albian species in Antarctica and in the Russian Far East, respectively. Dots for southern Sweden and Belgium/the Netherlands in fact represent more than one species, namely P. ignabergensis + P. bruennichi, and P. bruennichi, P. landenica + P. industriosa, respectively. Pycnolepas orientalis, from an unspecified Upper Cretaceous level in Azerbaijan, is here considered a nomen dubium (see text); P. nov. sp. from the upper Paleocene of Kazakhstan has not yet been described or illustrated.
