Recently more complete specimens have been found. This was probably used for killing their prey. It had a large, … Troodontidae is a family of bird-like theropod dinosaurs. They were found mainly in Mongolia, China and North America.

The Troodontidae is a family of small to medium-sized theropod dinosaurs. This thing suggests that troodontids had an acute sense of hearing, and that they used this sense while hunting, for localizing the prey. The smallest species was Most troodontids had sharp claws on their hands and feet. Below is a cladogram of the Troodontinae as published by Aaron van der Reest and Phil Currie, in 2017. They are only known from a few incomplete specimens from the Cretaceous periodof North America and Mongolia, so their exact affinities to other maniraptorans are uncertain. Această familie numită în anul 1924 de către paleontologul american Charles Whitney Gilmore a rămas puțin cunoscută până la sfârșitul scolului XX. During most of the 20th Century, troodontid fossils were few and scrappy and they have therefore been allied, at various times, with nearly every major coelurosaurian lineage. An egg-layer, it had behaviors in common with both crocodiles and birds; scientists are still uncertain about its status as an ancestor of either or both. The Troodontidae are a small group (maybe five different species) of very rare and hence poorly known maniraptorans. In addition to a bigger brain, Troodon possessed larger eyes than most theropod dinosaurs, a hint that it either hunted at night or that it needed to gather in all the available light from its cold, dark North American environment (another dinosaur that pursued this evolutionary strategy was the big-eyed Australian ornithopod

Troodon (or Troödon) is a genus of relatively small, bird-like dinosaurs, from the later part of the Cretaceous period, 75–65 million years ago.
