• Resumen

  • The dalmanitid and acastid trilobites are among the most common Bohemian Ordovician trilobites. They have a wide stratigraphical range from the Lower Ordovician Klabava Formation to the Upper Ordovician Kosov Formation where they constitute the most important elements of the "Hirnantia fauna". The aims of this contribution are to evaluate the possible dalmanitid and acastid exuviae and to distinguish the main types of moulting positions of these trilobites, their occurrence in dependence on the phyllogenetical position and overall body morphology.
