Additional late Silurian ostracoderms from the Leopold Formation of Somerset Island, North West Territories, Canada
£1.00
An ostracoderm fauna which includes Tolypelepis leopoldensis sp. nov., Corvaspis cf. C. arctica Loeffler and Dinely, and ?Kallostrakon sp. indet. occurs 30 m above the base of the Leopold Formation on Somerset Island in the Canadian Arctic Archipelago. Associated ostracods and conodonts indicate a Late Ludlovian or Pridolian age for the ostracoderm horizon. Although the lithology of the enclosing sediment suggests that it accumulated in intertidal conditions, the ostracoderms were not necessarily inhabitants of such an environment; some post-mortem transportation of the bony plates may have taken place.
