The middle section was previously considered to be the Pari Aike Formation. AgeThe middle section of the Mata Amarilla Formation has widely been regarded as Maastrichtian in age, but recent dating of a lava tuff layer shows that it dates back to 96.2 ± 0.7 Ma, during the Cenomanian.[1] {{clearboth}}Fossil content
