Saurornithoides
Saurornithoides was a small, fast, bird-like dinosaur that lived in the Late Cretaceous period. It had big eyes for seeing in the dark and a sharp claw on each foot to catch its prey. This smart hunter probably scoured the Gobi Desert for small mammals and reptiles.1

Datos curiosos
Saurornithoides had a large brain for its size, making it one of the smartest non-bird dinosaurs.1
Its eyes were huge and gave it excellent stereoscopic vision, which helped it judge distances when hunting at night.1
The first Saurornithoides fossil was found on July 9, 1923, by a Chinese employee of an American Museum of Natural History expedition named Chih.1
A baby Saurornithoides had very strong leg bones, suggesting that troodontid babies could walk soon after hatching and needed little parental care.1
It had a retractable sickle claw on the second toe of each foot, like its cousin Troodon.1
The name was originally going to be 'Ornithoides' (bird-like), but Henry Fairfield Osborn changed it to Saurornithoides when he formally described it in 1924.1
