Corpulentapus is an ichnogenus of Early Cretaceous theropod tracks known from China and South Korea[2]. The type ichnospecies C. lilasia is known from the Lower Cretaceous Longwangzhuang Formation and Yangjiazhuang Formation[3] in Zhucheng, China, and unnamed ichnospecies is known from the Lower Cretaceous Jinju Formation in Jinju, South Korea.
Corpulentapus is characterized by 'tulip-shaped' robust tridactyl, showing very broad and low-divaricated digits, and short central digit which indicates weak mesaxony. Based on these characteristics, tracks of Corpulentapus show similarities with ornithopod tracks, but asymmetric heel with the trace of metatarsal phalangeal pad IV posterior to metatarsal phalangeal pad II, and long steps represents this ichnotaxon represents theropod trackmaker.[1]
