Hadongsuchus
The binomial name “''Hadongsuchus acerdentis''” refers to the skull remain of an extinct "protosuchian" crocodyliform from the Hasandong Formation of Hadong, South Korea. Discovery The Hasandong Formation has been dated to the late Aptian and earliest Albian, between 118.0 ± 2.6 Ma and 112.4 ± 1.3 Ma. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. A complete fossil skull was discovered in 2002, and the genus was named in 2005 based on this fossil. 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 Hadon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hasandong Formation
The Hasandong Formation () is an Early Cretaceous ( Aptian to Albian) geologic formation in South Korea. It has been dated to the late Aptian and earliest Albian, between 118.0 ± 2.6 Ma and 112.4 ± 1.3 Ma. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. Tracks of the pterosaur ichnospecies ''Pteraichnus koreanensis'' have also been recovered from the unit.Y.-N. Lee, H.-J. Lee, J. and Y. Kobayashi. 2008.
