The Deinonychosauria ("fearsome claw lizards") is a clade of theropods in the Upper Jurassic and Cretaceous. The largest known of these was Utahraptor, and Anchiornis was the smallest.
The Dromaeosauridae includes some of the most fearsome killers of the Cretaceous Period: Deinonychus, Velociraptor, and Utahraptor. Troodontids date from the Upper Cretaceous and were lighter and slimmer than the dromaeosaurids. Some of these were Troodon and Saurornithoides.
