ka-ROH-no-SAWR-us
(Gr. Kharon (mythical boatman) + Gr. sauros "lizard") (m)
named for Charon, the boatman in Greek and Roman mythology who ferried the souls of
the dead across the River Styx in Hades; alluding to the discovery of the specimens
on the south bank of the Amur River, dividing China from Russia. Charonosaurus is a very large
lambeosaurine hadrosaur (estimated around 10.8 m (36 ft) long), known from a partial skull
(Holotype: CUST J-V1251-57 (Changchun University of Sciences and Technology, Changchun,
Jilin Province, China)) found in the Late Maastrichtian Yuliangze Formation,
west of Jiayin village, Heilongjiang Province, northeastern China.
Adult and juvenile hadrosaur remains discovered in the same area and formation likely
represent the same taxon and supply information on most of the postcranial skeleton;
the femur length was up to 1.35 m. (4.5 ft). The partial skull resembles that of
Parasaurolophus and probably had a similar long, backward-projecting hollow crest,
indicated by the highly modified dorsal surface of the frontal bones.
Charonosaurus is one of the largest hadrosaurs currently known from Asia and indicates
that lambeosaurines survived till the very end of the Cretaceous
(lambeosaurines are not known from the Late Maastrichtian in North America).
Type species: Charonosaurus jiayinensis [jyah-yee-NEN-sis] for the type locality at
Jiayin village, Heilongjiang Province, northeastern China. Ornithopoda Hadrosauridae
Lambeosaurinae Late Cretaceous (Late Maastrichtian) China [added 12-2000]
