Paleoecology of Auloporida: an example from the Devonian of the Holy Cross Mts., Poland

摘要: Abstract Substrate specificity of Auloporida (Tabulata) from the Skaly Fm. (Upper Eifelian–Lower Givetian) Holy Cross Mts., Poland, has been recognized. Kyrtatrypa sp., a rare species in formation (under 5%), was most often encrusted brachiopod (59% investigated specimens), while occurring brachiopod, Aulacella eifeliensis (de Verneuil) nearly not encrusted. The majority brachiopods were larger than 20 mm, smaller occur abundantly Formation. substrate caused mainly by ornamentation host's shell. position corallites along commissure shell proves that auloporids living hosts. epizoan probably used water currents produced brachiopod's lophophore impoverishing food composition, their relationship can therefore be described as scramble competition.
