Groenlandaspis in Antarctica, Australia and Europe


Groenlandaspis is a member of the Arthrodira, a group of Devonian armoured fishes. In the past Groenlandaspis has been found only in eastern Greenland but now Alexander Ritchie has recognised at least six species from sites in Greenland, Europe, Australia and Antarctica. His account demonstrates that these arthrodires enjoyed a very wide geographical distribution during the Upper Devonian and that the family can be traced back into the Middle and Lower Devonian.
