Any species of dinosaur which lives off eggs, such as Struthiomimus and Ornithomimus, comes under this name. The only named egg stealers to appear are Ozzy and Strut. The first egg stealer an Ornithomimus to appear is in the The Land Before Time, which attempts (unsuccessfully) to steal the egg which Littlefoot hatches from shortly afterwards. In The Land Before Time IV: Journey Through the Mists, a herd of egg stealers runs into the water. Ozzy and Strut may or may not have been some of the egg stealers that appeared. When the Great Earthshake starts two Egg Stealers ran.
