Description
| - Viz anglický abstrakt. (cs)
- Phragmoceras and Tubiferoceras are discosorid nautiloid genera with endogastric cyrtoconic to orthoconic breviconic shells possessing a contracted aperture. Due to the constricted aperture phragmoceratids have been usually considered as microphages. Nevertheless, the constriction of aperture appears during the late ephebic stage and preceding ontogenetic stages possessed a brevicone shell with an open aperture, usually considered to be indicative of nectobenthic predatory lifestyle. The apertural constriction probably improved hydrodynamic control and served as protection for soft body. Attachment sites of distinct retractor muscles give an evidence of potentially fast movement of the head-arm complex out of the aperture and the capture of larger prey.
