Originally described by Hans-Dieter Sues in 1978, this taxon represents one of the most characteristic small predators of the ecosystems of Laramidia during the Campanian, approximately 76–75 million years ago. Its name may be roughly translated as “lizard-bird thief,” referring to its nature as a light and gracile theropod, while the specific epithet \u003c\/span\u003e\u003cem\u003e\u003cspan\u003elangstoni\u003c\/span\u003e\u003c\/em\u003e\u003cspan\u003e honours the palaeontologist Wann Langston Jr.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe holotype of \u003c\/span\u003e\u003cem\u003e\u003cspan\u003eSaurornitholestes langstoni\u003c\/span\u003e\u003c\/em\u003e\u003cspan\u003e was described from fewer than thirty associated cranial and postcranial bones of a single individual from Dinosaur Provincial Park, although subsequent discoveries in Alberta and Montana have significantly expanded our knowledge of its anatomy. For decades, it was known mainly from isolated teeth and fragmentary remains, but new partial specimens have made it possible to study its skull, mandible, and diagnostic features in greater detail. These materials confirm its position within Dromaeosauridae, the group of maniraptoran theropods popularly known as “raptors,” characterized by light bodies, stiffened tails, agile hind limbs, and a well-developed sickle-shaped claw on the second toe.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eFrom a morphometric perspective, \u003c\/span\u003e\u003cem\u003e\u003cspan\u003eSaurornitholestes langstoni\u003c\/span\u003e\u003c\/em\u003e\u003cspan\u003e was a small dromaeosaurid, with an estimated body length of around 1.8–2 metres, an approximate hip height of 50–70 centimetres, and a mass probably within the range of only a few kilograms, generally lower than that of more robust dromaeosaurids such as \u003c\/span\u003e\u003cem\u003e\u003cspan\u003eDeinonychus\u003c\/span\u003e\u003c\/em\u003e\u003cspan\u003e. Its body would have been slender and lightly built, with relatively long hind limbs, metatarsi adapted for active locomotion, and an elongated tail stiffened by bony extensions that contributed to balance during rapid turns or agile movement. The arms were functional and relatively well developed, consistent with the anatomy of other dromaeosaurids, and were most likely covered with pennaceous feathers or equivalent structures, in accordance with the general evidence available for paravians and closely related dromaeosaurids.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eThe skull of \u003c\/span\u003e\u003cem\u003e\u003cspan\u003eSaurornitholestes langstoni\u003c\/span\u003e\u003c\/em\u003e\u003cspan\u003e was narrow and elongated, with jaws armed with small, recurved, serrated teeth adapted for slicing flesh. The study of new cranial specimens has made it possible to recognize important details of the anatomy of the snout, maxilla, dentary, and palatal region, revealing a predator with a lightly built but effective head for capturing small to medium-sized prey. Its dentition, very abundant in the fossil record of the Dinosaur Park Formation, indicates a carnivorous diet that may have included small vertebrates, juvenile dinosaurs, lizards, mammals, primitive birds, or carrion, within an ecosystem in which it lived alongside large tyrannosaurids, ceratopsids, hadrosaurids, ankylosaurs, crocodyliforms, turtles, and other small theropods.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"isSelectedEnd\"\u003e\u003cspan\u003eUnlike the popular image of large and powerful “raptors,” \u003c\/span\u003e\u003cem\u003e\u003cspan\u003eSaurornitholestes langstoni\u003c\/span\u003e\u003c\/em\u003e\u003cspan\u003e represents a lighter, faster, and more opportunistic dromaeosaurid model.
