Hadongsuchus


Hadongsuchus is an extinct genus of "protosuchian" crocodylomorph from the Hasandong Formation of Hadong, South Korea.

Discovery

The Hasandong Formation dates back to the Hauterivian and Barremian stages of the Early Cretaceous. A complete fossil skull was discovered in 2002, and the genus was named in 2005 on the basis of this holotype. Certain features of the third premaxillary tooth help distinguish it from other related crocodylomorphs. The estimated size of Hadongsuchus was around 50 cm in length. Like other protosuchians, it is believed to have been a fully terrestrial cursorial animal with a semi-erect posture. The binomial name of the type species H. acerdentis means "sharp-toothed crocodile from Hadong" in Greek.

Systematics

Hadongsuchus was recovered as a close relative of Shantungosuchus, Sichuanosuchus, and Zosuchus by Hangjae et al..
