Descripción
Sumario:The genus <i>Favrella</i> R. Douvillé has been recorded from Southern Patagonia (Argentina and Chile), Neuquén and Mendoza Provinces (Argentina), Santiago Province (Chile), Perú, Colombia, México, and U.S.S.R. Its supposed restriction to Southern Patagonia is doubtful. The age of Favrella is probably Haurerivian-Barremian; evidence for its suggested Aptian age is lacking. Patagoniceras Wetzel, 1960, is a probable junior subjective synonym of Favrella. No regional stratigraphic break between Berriasian and Aptian is evident in Southern Patagonia.
