Herrerasaurus was one of the earliest dinosaurs. Its name means "Herrera's lizard", after the rancher who discovered the first specimen. All known fossils of this carnivore have been discovered in rocks of Carnian age (late Triassic according to the ICS, dated to 231.4 million years ago) in northwestern Argentina.The type species, Herrerasaurus ischigualastensis, was described by Osvaldo Reig in 1963 and is the only species assigned to the genus. Ischisaurus and Frenguellisaurus are synonyms
Kids LOVE dinosaurs. Here’s a project based on the book If the Dinosaurs Came Back by Bernard Most. | We read the book, noting the many rectangular buildings and windows. It was an opportunity to practice all the lines we have learned. We could see wavy, zig zag, diagonal, vertical, horizontal, dotted and dashed lines. Day 2 we added the dinosaurs. 2 rules: the dinosaur had to be as big as a hand, and one color. The kids created the collage, then added details (lines, shapes and patterns).
