艾雷拉龍又名黑瑞龍，大約生活在２.３億年以前(晚三疊世)，是最古老的恐龍之一，發現於阿根廷，它證明了恐龍來源於同一個祖先。它與後來的肉食性恐龍有許多相同之處：銳利的牙齒、巨大的爪和強有力的後肢。牠們高約1公身尺，長3至4公尺，以其他小型爬行動物爲食。艾雷拉龍的骨骼細而輕巧，這使它成爲敏捷的獵手。艾雷拉龍耳朵裏的聽小骨顯示，這種恐龍可能具有敏銳的聽覺。

Herrerasaurus ischigualastensis is a basal theropod known only from the Upper Triassic Ischigualasto Formation of NW Argentina. Herrerasaurus is found in the lower third of the formation, which is Middle Carnian (~225-235mya) in age. The original specimen was discovered in 1959 by Osvaldo A. Reig and Victorino Herrera, and later named by Reig in 1963.

Herrerasaurus ischigualastensis was a 4 meter long, 300 pound biped. Some of the features that place it within Saurischia and Theropoda are the presence of a subnarial foramen, and an intramandibular joint. Despite its classification as a theropod by Sereno and Novas (1993), Thomas Holtz (1995) completed a phylogenetic analysis which placed Herrerasauridae as the sister group to the theropod-sauropodomorph clade, or even as the sister group to all Dinosauria.
