Troodon had a very large brain for its size—even larger, relatively speaking, than the brains of modern reptiles. It stood about 11 feet tall and weighed about 110 pounds.
Hypotheses about troodontid reproduction have been developed from this evidence (see In 2004, Mark Norell and colleagues described two partial troodontid skulls (specimen numbers IGM 100/972 and IGM 100/974) found in a nest of Troodontid feeding was discovered to be typical of coelurosaurian theropods, with a characteristic "puncture and pull" feeding method seen also in such theropods as the Troodontids are important in research into the origin of birds because they share many anatomical characters with early birds.
The alternate spelling Troödon shows that the ' o' s are pronounced separately, as in 'zoology'. Below is a cladogram of the Troodontinae as published by Aaron van der Reest and Phil Currie, in 2017.

By contrast, the eyes of many herbivorous animals are set toward the sides of their heads, an adaptation that allows them to detect the presence of approaching carnivores. In 1932, the American paleontologist Charles H. Sternberg erected the new genus Stenonychosaurus, which he classified as a basal theropod closely related to Coelurus. The name Troodon (pronounced TRUE-oh-don) derives from a single tooth discovered in 1856 by the famous American naturalist From CreationWiki, the encyclopedia of creation science This is primarily based on numerous specimens from China that appear to show evidence of feather-like structures, around the body.
