Troodon (/ ˈ t r oʊ. ə d ɒ n / TROH-ə-don; Troödon in older sources) is a former wastebasket taxon and a potentially dubious genus of relatively small, bird-like theropod dinosaurs definitively known from the Campanian age of the Late Cretaceous period (about 77 million years ago). It includes at least one species, Troodon formosus, known ...

Troodontidae / t r oʊ. ə ˈ d ɒ n t ɪ d iː / is a clade of bird-like theropod dinosaurs from the Late Jurassic to Late Cretaceous.During most of the 20th century, troodontid fossils were few and incomplete and they have therefore been allied, at various times, with many dinosaurian lineages.
Interest in the life history of Troodon continued in the 1990s with a study of its growth rates based on histological sections of fossils taken from a bonebed in Montana [4] and the apparent pairing of eggs in Troodon nests. [5] This decade also saw the first potential report of European troodontid remains, although this claim has been ...
