Ischigualasto - entering valley of the moon

Ischigualasto Provincial Park is also called Valle de la Luna ("Valley of the Moon"), due to its moon like appearance. The Ischigualasto Formation contains Late Triassic (Carnian) deposits (231.4 -225.9 million years before the present), with some of the oldest known dinosaur remains, which are the world's foremost with regards to quality, number and importance. This allows for the study of the transition between dinosaurs and ancient mammals. Research is ongoing. - scanned slide, Minolta X700
