Etymology: ‘ youngi ’ in honour of Dr Chung-Chien Young (official name Zhongjian Yang) for his contribution to the knowledge of Chinese fossil crocodylians.

Holotype: IBCAS QS15, incompletely preserved skull and left posterior part of lower jaw (Figs 2–6).

Type-locality and horizon: Xialou, Qianshan County, Anhui Province: lower part of the Upper Member of the Wanghudun Formation, Shanghuan Asian Land Mammal Age (Wang et al., 2016a), late Danian, early Palaeocene (Wang et al., 2019).

Diagnosis: Basal crocodyloid differing from other crocodyloids by the following unique combination of characters: large size of the maxillary foramen for cranial nerve V; parietal–squamosal suture on skull table elevated on a ridge; acute indentation on the sagittal axis of the supraoccipital and parietal; dorsal margins of orbits upturned; supraoccipital largely exposed on skull table; anteroposterior prominent ridge on the lateral surface of the surangular.
