Sarcolestes is a little known genus of the bird pelvic dinosaur (Ornithischia) from the group of the ankylosauria .
So far only a partially preserved lower jaw is known from Sarcolestes , which has an ornamentation on the outside. Otherwise nothing is known about the physique of this dinosaur.
The fossil remains of Sarcolestes were found in Cambridgeshire , England and first described by Richard Lydekker in 1893 . The name means "meat robber" because Lydekker thought the find was a carnivorous dinosaur. It was only in the 1980s that Peter Galton discovered that it was an ankylosaur. The type and only known species is S. leedsi .
The find is dated in the Middle Jurassic ( Callovian ) to an age of approx. 166 to 163 million years, making Sarcolestes the oldest known representative of the Ankylosauria. Sometimes it is classified within the Ankylosauria in the Nodosauridae , M. Vickaryous et al. (2004) consider the find to be too sparse for a more precise systematization and list it as Ankylosauria incertae sedis .
