  Sierra Perenchiza Formation (Spain) | |
The Sierra Perenchiza Formation is a geologic formation in Spain. A late Campanian to early Maastrichtian age is supported by paleomagnetic data and fossil pollen analysis.[1] The Sierra Perenchiza Formation "consists mainly of interbedded carbonate marls and lacustrine limestones, interpreted as deposits of small ephemeral lakes and ponds of a coastal environment".[2] Vertebrate fossils are common in the formation: these include dinosaurs, pterosaurs, crocodylomorphs, turtles, squamates, frogs, albanerpetontids, and ray-finned fish, as well as dinosaur eggshell fragments. Also known are freshwater invertebrates (ostracods, gastropods, and bivalves) and plant remains.[2]
