Dromaeosauridae includes some of the most fearsome killers of the Cretaceous Period: Deinonychus, Velociraptor, and Utahraptor. The largest known of these was possibly Utahraptor, and Microraptor was among the smallest (40 cm or 16 in).
Troodontids date from the late Cretaceous Period and were lighter and slimmer than the dromaeosaurids. Some of these were Troodon and Saurornithoides.
By some definitions, Deinonychosauria and Dromaeosauridae are synonyms.

Scientific classification or biological classification is a method by which biologists group and categorize species of organisms. Scientific classification also can be called scientific taxonomy, but should be distinguished from folk taxonomy, which lacks scientific basis.

A geologic period is a subdivision of geologic time that divides an era into smaller timeframes. The equivalent term used to demarcate rock layers and the fossil record is the system; thus the rocks of the Devonian System were laid down during the Devonian Period.
