Theropod and other dinosaurian tracks from the upper Lower Cretaceous of northeastern China: Overlooked Fuxin Biota records reinvestigated

Dinosaur tracks have been known and reported sporadically from the coal-bearing beds of the Fuxin Formation (upper Aptian-Albian, upper Lower Cretaceous) of Liaoning Province, northeastern China for some time but have not been described in detail. Here available material is illustrated suggesting a diversity of theropod track morphotypes, including small grallatorid, eubrontid and possible Gigandipuslike forms, a Magnoavipes-like form and an isolated small ornithopod track. Some of the tracks show the characteristic distortion of flattened footprints. The ichnofauna supplements our knowledge of the Fuxin Biota by adding a more diverse dinosaur fauna, indicated by the footprint record. 0 2022 Elsevier Ltd. All rights reserved.
