description Troodon formosus Overview
Troodon formosus is the name given in 1856 to a small, serrated theropod tooth from the Late Cretaceous of Montana. Because the original specimen is isolated and lacks features sufficient for reliably associating it with more complete skeletons, many paleontologists regard the name as a dubious taxon. Animals once broadly reconstructed as Troodon are now commonly discussed through better-supported troodontid genera rather than this tooth-based species.
help Troodon formosus FAQ
What is Troodon formosus?
Troodon formosus is the name given in 1856 to a small, serrated theropod tooth from the Late Cretaceous of Montana. The name is historically important, but the isolated tooth does not securely identify a complete dinosaur skeleton.
Why is Troodon formosus controversial?
The original specimen is an isolated tooth with too few features to link it reliably to a complete skeleton. For that reason, many paleontologists treat the name cautiously or regard its use as uncertain.
What did Troodon formosus eat?
The serrated tooth indicates a theropod dinosaur with a tooth adapted for cutting or gripping food. The isolated specimen does not provide enough evidence to reconstruct a precise diet.
When and where was the original Troodon formosus specimen found?
The name was established in 1856 from a tooth from the Late Cretaceous of Montana. Because the specimen was isolated, later identification has remained difficult.
