  • Record of Moridae (Teleostei: Gadiformes) from the Chenque Formation (Late Oligocene- Early Miocene) from the Chubut province, Argentina. A nearly complete specimen belonging to thefamily Moridae is described in this paper. The material has been collected in outcrops referable to the ChenqueFormation (Oligocene-Miocene) from the Chubut province, Argentina. The specimen constitutes the first fossilrecord for the Gadiformes in Argentina and one of the first osteological occurrences for Moridae. The morphologyof the specimen suggests affinities with the genera Physiculus and Salilota. The presence of Moridae in the EarlyMiocene of Patagonia and New Zealand is in agreement with previous hypotheses suggesting marine transantarcticconnections between both landmasses during Late Oligocene - Early Miocene times.
