Doppellagige Kronenplatten: Ein neues anatomisches Merkmal paläozoischer Crinoiden und Revision der Familie Cupressocrinitidae (Devon)

The Odivelas Limestone: evidence for a Middle Devonian reef system in western Ossa-Morena Zone (Portugal)

“…also Robustocrinites and Abbreviatocrinites Bohatý, 2005, newly defined but considerably sympatrical forms). In spite of general uncertainty about the crinoid columnal determination, the illustrated morphology is considerably different in comparison with any older (Emsian-Eifelian) or younger (Givetian-Frasnian) crinoid columnals which possess four accessory canals, e.g.…”

Revision of the Flexible Crinoid GenusAmmonicrinusand a New Hypothesis on Its Life Mode

“…13H) was encrusted by two microconchid−valves, which settled postmortem at the facet region of the ossicle, below and above the crenularium. Microconchids with unstructured or sculptured valves fre− quently encrusted the ossicles of cupressocrinids from the Middle Devonian of the Eifel, as reported by Bohatý (2005bBohatý ( , 2006bBohatý ( , 2009. It is remarkable that larger individuals are rare and isolated (compare to Bohatý 2006b: pl.…”

“…Bohatý (2009: fig. 11.1) re− ported stems of Halocrinites geminatus (Bohatý, 2005b) and Procupressocrinus gracilis, which were encrusted by fene− strate bryozoans. The length of the overgrown pluricolum− nals, as well as some observed embedding patterns of bryo− zoans located underneath the attached stem, allows the pre− sumption of a premortem settlement (compare to Bohatý 2005b: fig.…”

Revision of the Chen and Yao Devonian to Permian crinoids from Western Yunnan

“…Remarks Bohatý (2005Bohatý ( , 2006b questionably assigned Cupressocrinites deltoides Chen and Yao, 1993 to Abbreviatocrinites inflatus (Schultze, 1866). We question the assignment of C. deltoides to Cupressocrinites Goldfuss, 1831 or Abbreviatocrinites Bohatý, 2005 because the cup is more conical with concave walls than the bowl-shaped or conical cup with convex walls of either of those genera.…”
