Abstract

The recent biostratigraphic and micropaleontologic works permitted to specify the distribution of Megaporella boulangeri Deloffre and Beun in the Jurassic of the Moroccan Atlantic basin. The lower limit of the extension of this dasycladale alga, earlier attribued to the Early Kimmeridgian by Deloffre and Beun (1986), is currently placed in the Early Callovian, on the basis of the age provided by Megaporella boulangeri biozone. The Otternstella arabica biozone dates the upper limit of the extension of the species of the Early Oxfordian. Megaporella boulangeri proliferates in the borders of the basin where the internal lagoons facies dominate, however it is absent in the western parts with open sea facies. © 2007 Elsevier Masson SAS.
