Euparkeriidae

Euparkeria (; meaning "Parker's good animal", named in honor of W. K. Parker) is an extinct genus of archosauriform reptile from the Triassic of South Africa. Euparkeria is close to the ancestry of Archosauria, the reptile group that includes crocodilians, pterosaurs, and dinosaurs (including birds).

Euparkeriidae is an extinct family of small carnivorous archosauriforms which lived from the Early Triassic to the Middle Triassic (Anisian). While most other early archosauriforms walked on four limbs, euparkeriids were probably facultative bipeds that had the ability to walk on their hind limbs at times. The most well known member of Euparkeriidae is the species Euparkeria capensis, which was named by paleontologist Robert Broom from the Karoo Basin of South Africa in 1913 and is known from several nearly complete skeletons. The family name was first proposed by German paleontologist Friedri

Osmolskina is a genus of archosauriform reptile which lived during the Early Triassic in what is now Poland. The type species, Osmolskina czatkowicensis, was described by Magdalena Borsuk−Białynicka and Susan Evans in 2003. The generic name honors the late female Polish paleontologist Halszka Osmólska. ==Resemblance to Euparkeria== Osmolskina closely resembles the well-known genus Euparkeria. The authors of the 2003 paper considered classifying Osmolskina within the family Euparkeriidae, noting the animal's close resemblance to Euparkeria, but concluded that "Euparkeriidae remains monotypic be

Halazhaisuchus is an extinct genus of archosauriform from the Early Triassic of China. It is known from a single species, Halazhaisuchus qiaoensis, which was named in 1982 from the lower Ermaying Formation in Shaanxi. It was assigned to the family Euparkeriidae as a close relative of the genus Euparkeria from South Africa. Halazhaisuchus is known from a single holotype specimen called V6027, which was discovered in 1977 and includes a portion of the vertebral column, some ribs, two scapulae and two humeri, the right radius and ulna, and a left coracoid. Two rows of plate-like bones called oste
