Description
Source: Wikipédia
La formation de Santa Maria est une formation géologique du Trias située dans l'état de Rio Grande do Sul au Brésil.
Son âge géologique est à cheval sur une partie du Trias moyen et du Trias supérieur, soit environ entre −245 et −225 Ma (millions d'années).
Cette formation a livré une abondante faune fossile de vertébrés, dont les dinosaures Staurikosaurus, Saturnalia, Pampadromaeus, Gnathovorax et Buriolestes, ce dernier ayant été découvert aux côtés du dinosauromorphe Ixalerpeton.
