Santa Maria Formation
From Wikipedia, the free encyclopedia
The Santa Maria Formation is a sedimentary rock formation found in Rio Grande do Sul, Brazil. It has a late Ladinian – early Carnian age (Middle – Upper Triassic), and is notable for its fossils of early dinosaurs, including the herrerasaur Staurikosaurus, the basal saurischian Teyuwasu, and the basal sauropodomorph Saturnalia.[1] It received this name because it was discovered first in the city of Santa Maria.
