  Anfiteatro de Ticó Formation (Argentina) | |
The Anfiteatro de Ticó Formation is a geological formation from the Deseado Massif in the province of Santa Cruz, Argentina.
The Anfiteatro de Ticó preserves a rich and diverse flora including macrofossils, mesofossils, and microfossils. These have been object of detailed investigations since the 1960'. [1] [2] [3]
The formation is of continental origin, and includes riparian and lacustrine deposits.
The following fossils were reported from the formation: [4]
