Etymology: "Silesaurids" is the plural of "silesaurid," a noun for members of the group of extinct reptiles that the word names. The first part of the term points to the genus "Silesaurus," named after Silesia, the historical region in central Europe where the first fossils of these animals were found. The "-id" ending is the standard scientific suffix for members of a family or group, so a silesaurid is one of the animals belonging to the Silesaurus lineage. Silesaurids are placed in a clade just outside the dinosaurs proper, showing how the dinosaur family tree branched off from its close relatives. They lived during the Triassic period, and their varied body forms and ecological roles make them useful for understanding how early dinosaur relatives diversified.
