Q What did a 2025 study propose regarding the classification of Stenonychosaurus and Troodon?

- A Classifying Stenonychosaurus within the tyrannosaur family
- B Retaining the name Troodon formosus as the preferred name
- C Reclassifying Stenonychosaurus as a modern bird
B Retaining the name Troodon formosus as the preferred name
A 2025 study proposed giving the name Troodon formosus priority over Stenonychosaurus inequalis.
The study also proposed designating a specimen discovered in the Two Medicine Formation in Montana as a new type specimen (neotype) for Troodon in an effort to stabilize its classification.
However, the taxonomic debate has not yet been fully resolved.
