Euparkeria capensis (Broom 1913) Early Triassic, ~247 mya, 60 centimeter length, was derived from a sister to Garjainia and preceded Riojasuchus, Ornithosuchus, Arizonasaurus and Vjushkovia.
Distinct form Garjainia, Euparkeria had relatively smaller skull. It had a larger naris, antorbital fenestra and orbit, which means the surrounding bones were lighter, more gracile. The jugal did not have such a sharp descent. The maxilla was not strongly convex ventrally and no distinct notch developed between the premaxilla and maxilla.
All the neural spines were lower and the tail was relatively longer.
The pectoral girdle was smaller. Then medial metacarpals were larger than the lateral ones in diameter.
The pubis and ischium has a continuous ventral rim. The pedal metacarpals and digits were also larger in diameter medially. Pedal digit IV was shorter than III and V was reduced to a vestige. The metatarsals were longer than the digits.
