A new chondrichthyan from the Wenlock, Lower Silurian, of Baillie-Hamilton Island, the Canadian Arctic

Kannathalepis milleri, gen. et sp. nov. is described from the Upper Sheinwoodian to Lower Homerian interval (Wenlock) of the Baillie-Hamilton Island section, Canadian Arctic. Based on several distinct features, such as the occurrence of several canals in the neck region, much smaller length of the wide and short base compared to the crown, presence of compound scales, character of dentine canals and tubules, and specific ultrasculpture of the crown, the new taxon Kannathalepis milleri, gen. et sp. nov. is assigned to Kannathalepididae fam. nov. of uncertain order of the subclass Elasmobranchii, class Chondrichthyes.
