Description

Aalenian-Bajocian phylloceratid ammonites, typically oceanic, are being increasingly recorded in the Neuquén Basin. In this paper we describe three species, one of them new: Costiphylloceras limayense n. sp. The other two are: Phylloceras perplanum (Prinz) and Calliphylloceras cf. achtalense (Redlich). According to the literature Calliphylloceras and Phylloceras are the most common phylloceratid genera in the Andean Aalenian.
