BIOSTRATIGRAPHY, PALEOECOLOGY, AND TAXONOMY OF DEVONIAN (EMSIAN AND FAMENNIAN) CRINOIDS FROM SOUTHEASTERN MOROCCO
|
ABSTRACT-
An early late Emsian codiacrinid and Frasnian specimens of an indeterminate species of Parapisocrinus, an undesignated new genus of a catillocrinid, and two amabilicrinids are described from the eastern part of the Anti-Atlas Mountains of Morocco. These are the first articulated
crinoid specimens reported from the Famennian of Morocco. Specimens occur within ammonoid-rich dysoxic shales, marls, and thin limestones at Ouidane Chebbi, Jebel Mrakib, Lambidia, and Rich Bou Kourazia. Parapisocrinus, the codiacrinid, and the catillocrinid are loose cups that are associated with other ...
