| Abstract |
The study of the Maastrichtian Deccan Intertrappean otolith association allows for the reconstruction of a fish fauna of 22 taxa, of which 16 are identified at species level. Three species are new: “genus Heterotidinarum” heterotoides, “genus Percoideorum” citreum and Dapalis erici. The represented taxa include typical freshwater ones, essentially freshwater ones with some marine intruders, near shore marine groups including a significant portion of freshwater intruders and predominantly marine fishes, including however some scarce freshwater residents. The most probable interpretation of such an association is that the Deccan Intertrappean Beds correspond to freshwater environments of a coastal area, where intrusion by marine elements or temporary connections with the marine realm existed. The Indian Maastrichtian and Ypresian faunas are compared with the European fossil record. The fossil record of osteoglossids, ambassids, and channids points to ancient Eurasiatic affinities of European freshwater and brackish Paleogene and Early Miocene fish faunas. |
