Beatricea from the Ordovician of Hall Land, North Greenland

Abstract

Large, somewhat irregular cylinders of the supposed stromatoporoid genus Beatricea Billings, 1857, have frequently been reported from Ordovician strata. Sokolov (1962) noted the occurrence of 14 species from the Ura1s, Siberia, Novaya Zemlya and North America, in addition to representatives of the closely related genera Aulacera Plummer, 1843 and Cryptophragmus Raymond, 1914. Although diverse Ordovician faunas were described from Greenland by Troedsson (1928), Poulsen (1927) and Teichert (1937), no record has previously been made of these genera in Greenland. It is therefore of some interest that specimens of Beatricea have now been identified in collections made by J. H. Allaart and P. R. Dawes in 1965 during 'Operation Grant Land' from Kap Ammen, on the northern coast of Hall Land, North GreenIand.
