Note: Extinct order of reptiles characterized by triradiate pelvis with the inferior pelvic elements directed downwards, a subnarial foramen, some reduction in digits, forelimbs that are usually distinctly shorter than hind limbs, and three to seven sacral vertebrae. Includes all theropod carnivorous dinosaurs and one of the two great lineages of herbivorous dinosaurs. Dating from the Upper Triassic to Upper Cretaceous, after which all non-avian saurischians became extinct.

Additional Notes: |
|
| Chinese (traditional) ..... 已滅絕的爬蟲類，特色是具有三叉狀的骨盆，且下方骨盆朝下。具一鼻下孔，三到七塊薦椎，足趾的數量減少，前肢明顯較後肢短。蜥臀目包含所有獸腳類肉食性恐龍，以及兩大系草食性恐龍其中一系。活躍於上三疊紀時期至上白堊紀時期，此後所有的非鳥類蜥臀目恐龍便完全滅絕。 |
| Dutch ..... Uitgestorven orde van reptielen die werd gekenmerkt door een triradiaat bekken waarbij de onderste bekkenelementen benedenwaarts zijn gericht, een foramen subnarialis, enigszins gereduceerde vingers, voorste ledematen die doorgaans duidelijk korter zijn dan de achterste ledematen, en drie tot zeven sacrale wervels. Hiertoe behoren alle theropode vleesetende dinosaurussen en een van de twee grote families van plantenetende dinosaurussen. Kwam voor in het late Trias tot het late Krijt, waarna alle niet-vliegende Saurischia uitstierven. |
