Guillermo Chong

Guillermo Baltazar Chong Díaz is a Chilean geologist and professor at the Catholic [University of the North] at Antofagasta, Chile. In 2018 he was named distinguished son of Arica. The mineral chongite and the extinct fish Chongichthys are named after him.
In 2011, together with Zulma [Brandoni de Gasparini] and others, Chong Díaz discovered a well-preserved fossilized skull of the family Metriorhynchidae. The team determined it to be a specimen of Metriorhynchus westermanni, an extinct marine crocodyliform.
