Avisaurus lived about 68 to 66 million years ago, right before the dinosaurs went extinct.1

It was one of the largest enantiornithine birds, weighing up to 1.7 kilograms (3.7 pounds).1

The first fossil of Avisaurus was a single foot bone called a tarsometatarsus, found in Montana in 1975.1

Scientists first thought Avisaurus was a non-avian dinosaur, but later realized it was an ancient bird.1

Avisaurus had curved claws on its feet, similar to those of raptor dinosaurs, which helped it catch prey.1

It lived in swamps and river basins along the western shore of a huge sea that split North America.1
