Resumo

OUTCROP OF THE LIMA CAM-POS BASIN, CEARÁ, BRAZIL.New vertebrate finds, probably Neocomian (Early Cretaceous) in age, from an outcrop near the locality of Cascudo, Municipality of Icó, Ceará State, are added to the abundant and well-known remains of ganoid scales attributed to Lepidotes sp. in the Lima Campos Basin.These new specimens comprise remains of coelacanth fishes (including a right fragmented mandibular ramus and fragmented remains of a quadrate, an angular and a prootic), three hybodont teeth identified as Planohybodus sp., and a complete crocodilomorph osteoderm.These new finds were discovered in the fine-grained red sandstone from Malhada Vermelha Formation.This study reveals the high and still little explored paleontological richness of the Lima Campos Basin, and points to the fossiliferous potential of others small northeastern Brazilian inner basins.
