Abstract

Abstract: A new ankylosaurid species of Crichtonsaurus, C. benxiensis sp. nov., is erected based on a well preserved skeleton and a nearly complete skull found in the Sunjiawan Formation (Cenomanian‐Turonian), Beipiao, Liaoning Province. Crichtonsaurus benxiensis sp. nov. is characterized by width 84.6% of length of the skull, a deep depression located medial to the notch between the orbit and the squamosal horn, paroccipital processes fused to the quadrates, fused scapula and coracoid, a large foramen for the supracoracoid nerve to enter the coracoid and to exit out from the scapula. Based on the new specimen, Crichtonsaurus is assigned to Ankylosauridae.
