the apex landlord of the Cretaceous, evicting everything with teeth the size of bananas
means A tyrannosaur is any of a family of large carnivorous dinosaurs, most famously Tyrannosaurus rex, that walked on two powerful legs with tiny forelimbs and ruled the late Cretaceous food chain.
from From Greek 'tyrannos' (tyrant, absolute ruler) plus 'sauros' (lizard) — literally 'tyrant lizard.' The name Tyrannosaurus rex was coined in the early 20th century by paleontologist Henry Fairfield Osborn, who added Latin 'rex' (king) to crown it: the tyrant-lizard king. 'Sauros' is the same root lurking in countless dinosaur names, while 'tyrannos' came to English through the same Greek lineage that gives us 'tyrant' and 'tyranny.'
