Sinornithoides youngi

Not to be confused with Saurornithoides — meaning "lizard bird form" — Sinornithoides is a "Chinese bird form". Actually, they're both Chinese and they're both bird forms, or bird-like, though the latter is much smaller despite being much older.

Sinornithoides is based on a virtually complete skeleton with a relatively small skull and small serrated teeth that was hauled from the Ejinhoro Formation in 1988. With its snout tucked under its left arm, it was discovered in a similar "sleeping" position to its close relative Mei long, though it cunningly avoided being roasted in the feather by not sleeping anywhere near an active volcano. Poor old Mei long.
(Young's Chinese bird form)Etymology
Sinornithoides is derived from the Latin "Sinae" (Chinese), and the Greek "ornis" (bird) and "-oides" (like, form), named for its bird-like appearance and discovery in China. The species epithet, youngi, honors Chung Chien Young (aka C.C Young, aka Yang Zhongjian) the "Father of Chinese vertebrate paleontology".
Discovery
The remains of Sinornithoides were discovered in the Ejinhoro Formation at Huamuxiao, Ordos Basin, Inner Mongolia, northern China, by the joint Canadian/ Chinese expeditions to Inner Mongolia in 1988.
The holotype (IVPP V9612) is an almost complete skeleton.
