Candelária Formation, Paraná Basin (Brazil) | |
The Candelária Formation is composed of mudstones and sandstones deposited in a lacustrine to deltaic (distal floodplain) environment. It overlies the Santa Maria Formation and is partly overlain by and partly laterally equivalent to the Caturrita Formation. The formation comprises two Assemblage zones; the older Hyperodapedon and the younger Riograndia Assemblage Zones. Several cynodonts and other therapsids as well as early dinosaurs were found in the formation in the vicinity of Agudo.
