  Mulichinco Formation (Argentina) | |
The Mulichinco Formation is a geological formation in Argentina. It is Valanginian in age and is predominantly terrestrial, being deposited at a time of marine regression in the Neuquén Basin, and predominantly consists of siliciclastic rocks. [1]
Fossil content
Dinosaur remains have been found in the formation, including those of the dicraeosaurid Pilmatueia [2] and carcharodontosaurid Lajasvenator. [3] Flora recovered from the formation includes the tree fern Tempskya dernbachii and horsetail Equisetites. [4]
