Zapsalis is known only from its teeth, not from any other bones. Scientists call it a 'tooth taxon'.1

The name Zapsalis means 'thorough scissors' in Greek, because its teeth look like sharp scissors.1

Zapsalis lived between about 85 and 66 million years ago, during the Late Cretaceous.2

Its teeth have rounded denticles (little bumps) and vertical grooves, which help scientists tell them apart from other raptor teeth.1

Some scientists think Zapsalis teeth might have been used for preening feathers, like some other raptors.1

Zapsalis was named by famous fossil hunter Edward Drinker Cope in 1876, during the 'Bone Wars' with his rival Othniel Charles Marsh.1
