Dromaeosaurus, meaning "swift running lizard" is a genus of dinosaur that lived approximately 75 million years ago during the later part of the Cretaceous Period. (Ottawa, Canada, June 2015)

Life restoration of Kansaignathus sogdianus. Modified from drawing of generic dromaeosaur to match figures of the holotype mandible in the description and skeletal reconstructions of related dromaeosaurs.

Jian is a microraptorine dromaeosaur, and the only non-avian dinosaur so far discovered from the Xiagou Formation of what is now China. Typical of microraptorinae, Jian had long pennaceous feathers growing from its arms as well as its legs, and was small in size, growing to approximately 1 m in total body length.

Diuqin is an unenlagiine dinosaur from the Late Cretaceous of what is now Argentina. Unenlagiines, known exclusively from South America, are usually classified as dromaeosaurs though this is sometimes debated. Like dromaeosaurs, they were covered in feathers, carnivorous, and had the large sickle-like claw on the inner toe of each foot. Unique to unenlagiines is their elongated snout, suggesting a piscivorous diet. Diuqin was a medium-sized unenlagiine, at about 4 m in length.
