Camadas de Guimarota


The Camadas de Guimarota, simply Guimarota, or Camadas de Alcobaça is a disused coal mine near the city of Leiria in central Portugal. The mine is within layers of the Alcobaça Formation, Kimmeridgian age of the Late Jurassic period, it contains a diverse array of fossil animals and plants, including dinosaurs and mammals.
The locality was extensively worked by paleontologists from the Free University of Berlin, but this activity stopped in 1982. Further excavations are considered to be unlikely, since the mine is now flooded. Pumping it out and rendering it safe again would be prohibitively expensive.
The mammal remains from this site are of particular note. The excavations were so successful that many of the recovered remains have yet to be studied.
