The Alcobaça Formation, previously known as the Guimarota Formation and also known as the **Consolação Unit, ** is a geological formation in Portugal. It dates back to the Kimmeridgian stage of the Late Jurassic. It is an important source of information on the diversity of Late Jurassic mammals. Many of the fossils were collected from the now disused and flooded Camadas de Guimarota coal mine.
