Chitinozoaires du Llanvirn (formation de Table Head) de la partie occidentale de Terre-Neuve, Canada
A chitinozoan microfauna is described from the middle part of the Table Head Formation (Diplograptus decoratus Zone, Llanvirn age). It includes Fustichitina langei, Conochitina poumoti, Conochitina pirum, Conochitina subcylindrica, Conochitina cf. C. bulmani, and Desmochitina cf. D. lata. Considerin...
