Bambiraptor was a small, bird-like, feathered dromaeosaurid dinosaur that lived 72–75 million years ago during the Late Cretaceous in Montana. Roughly 3–4 feet long and weighing under 10 lbs, it was a swift, agile carnivore with a large brain-to-body ratio, a signature sickle claw on each foot, and potentially opposable fingers.

Key Facts About Bambiraptor
- Discovery: A near-complete (95%) juvenile skeleton was discovered in 1993 by 14-year-old Wes Linster in Glacier National Park, Montana.
- Appearance: Covered in feathers, Bambiraptor looked very similar to a modern bird, featuring long arms, a wishbone, and a sternum, leading to speculation that it may have been capable of flight or gliding.
- Size: It was small, measuring about 3 feet (0.9 meters) long, though adults may have reached up to 1.3 meters (4.3 feet) in length.
- Behavior: It was a fast, vicious, bipedal carnivore that likely hunted in packs to take down larger prey.
- Intelligence: It had a relatively large brain compared to its body size, similar to that of modern birds.
- Name Origin: The name means “baby robber” (referring to the juvenile specimen) and is a nod to the Disney character, Bambi.

Habitat and Ecology
- Time Period: Lived during the Late Cretaceous, specifically the Late Campanian period, around 72–75 million years ago.
- Location: The fossils were found in the Upper Two Medicine Formation in Montana, indicating a habitat that was likely warm and forested, featuring rivers and, at that time, a coastal plain.
- Diet: A carnivore, hunting small animals like lizards and mammals.

Scientific Significance
- “Rosetta Stone” Fossil: Due to its completeness, Bambiraptor provides significant insights into the evolution of birds from dinosaurs.
- Phylogenetic Position: It is a key member of the dromaeosaurs, the group of theropods most closely related to birds.
- Debate: Some paleontologists debate whether Bambiraptor is a distinct genus or if the specimen is actually a juvenile of the species Saurornitholestes.
