Abstract (in czech)
   Klasifikace macluritidních gastropodů na základě studia typového materiálu ze spodního ordoviku v Coloradu, USA
Abstract (in english)
   Study of the oldest macluritid gastropod, Macluritella stantoni Kirk, 1927 from the Lower Ordovician of Colorado, has revealed that its early whorls are openly and dextrally coiled, in contrast to those in later teleoconchs which are sinistrally coiled. This is the first documentation of heterostrophic coiling in members of the Macluritoidea, which have been considered to be dextrally hyperstrophic.
