Laguna Palacios Formation

The Laguna Palacios Formation is a Maastrichtian geologic formation of the Chubut Group in the Golfo San Jorge Basin in Patagonia, Argentina. The formation partly overlies and partly is laterally equivalent to the Lago Colhué Huapí Formation and is overlain by the Salamanca Formation of the Río Chico Group.^[1] The formation comprises tuff reworked by fluvial activity and paleosols. The Laguna Palacios Formation has provided fossilized bee nests.^[2] Dinosaur remains, such as Notoceratops, diagnostic to the genus level are among the fossils that have been recovered from the formation.^[3]
