Groelandaspis sp.
Phylum: Chordata Haeckel, 1874
Subphylum: Vertebrata Cuvier, 1812
Classe:
Ordine: Arthrodira Woodward, 1891
Famiglia: Groenlandaspididae Obruchev, 1964
Genere: Groelandaspis Heintz, 1932
Specie e sottospecie
Il genere annovera attualmente le seguenti specie: Groenlandaspis antarctica Ritchie, 1975 - Groenlandaspis disjectus Woodward, 1891 (in origine Coccosteus disjectus) - Groenlandaspis pennsylvanica Daeschler et al., 2003 - Groenlandaspis potyi Olive et al., 2015 - Groenlandaspis riniensis Gess and Hiller, 1995 - Groenlandaspis seni Janvier and Ritchie, 1977 - Groenlandaspis thorezi Heintz, 1932.
Descrizione
Il Groenlandaspis era un placoderma artrodire, che significa che aveva un collo articolato, qualcosa che permetteva ai placodermi dell'arthordire di spalancare la bocca. I membri famosi degli artrodiri includono il Dunkleosteus.
Diffusione
Fu scoperto per la prima volta in Groenlandia, ma da allora sono stati trovati esemplari individuali provenienti da tutta Europa, Australia e Antartide, indicando una possibile distribuzione globale di questo genere.
