| Abstract: | Seven Silurian pisocrinids are described,including Pisocrinus (Pisocrinus) pilula,Pisocrinus (Granulosocrinus) kosovensis, Pisocrinus (Granulosocrinus) brevis sp. nov., Pisocrinus (Granulosocrinus) bohemicus,Parapisocrinus ollula, Parapisocrinus spherices,and Parapisocrinus pateriformis sp. nov. Within P. (G.) bohemicus,eight intraspecific variations are recognized,with internal structures inside calyx illustrated and discussed. A symmetrical study is given to Parapisocrinus pateriformis sp. nov.,which discloses an abnormal symmetrical axis. |
