the apex predator that ruled Jurassic plains 80 million years before T. rex was born
means A large carnivorous dinosaur of the Late Jurassic period, walking on two legs with short arms, a heavy skull, and sharp serrated teeth.
from From the Greek 'allos' (other, different) plus 'sauros' (lizard) — literally 'different lizard,' a name chosen because its vertebrae were unlike those of any reptile then known. The term was coined in the 19th century by American paleontologist Othniel Charles Marsh, during the bone-hunting fervor of his era. 'Sauros' is the same root that ends 'dinosaur' (terrible lizard) and countless other prehistoric names.
