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 (es|hijo ilustre) of Arica.[1] The mineral chongite and the extinct fish Chongichthys are named after him.[2] [3]
In 2011, together with Zulma Brandoni de Gasparini and others, Chong Díaz discovered a well-preserved fossilized skull of the family Metriorhynchidae.[4] [5] The team determined it to be a specimen of Metriorhynchus westermanni, an extinct marine crocodyliform.
