A collection of camenellan tommotiid sclerites from the Transantarctic Mountains have been re-examined. New data shows that Dailyatia sp. A is found alongside Dailyatia odyssei Evans and Rowell 1990 in the Early Cambrian Shackleton Limestone, as in the Arrowie Basin of Australia. A further examination of Shackleton Limestone sclerites, similar to others previously described as Kennardia sp. A and Kennardiasp. B, suggests that the Shackleton Limestone also contains a further species of camenellan. A further examination of the detail of ornamentation and gross morphology ofthese sclerites suggests that they are more likely to be a further species of Dailyatia, rather than Kennardia. A new species of Dailyatia is also reported from the Early Cambrian "Schneider Hills Limestone" formation of the Argentina Range. No overlap is found in sclerite morphologies between the Botomian-aged Schneider Hills and the temporally equivalent Shackleton Limestone, indicating a spatial influence on the distribution of tommotiids in the Cambrian of Antarctica.
