Serra de Aire ...
The Footprints National Monument in the far east of Serra de Aire in the village of Quarter, in the Natural Park of Serra de Aire and Lamps, contains an important fossil record of the Jurassic period, in the footsteps of some of the largest creatures that ever roamed the planet Earth: the sauropod dinosaurs, the limestone slab where the footprints of dinosaurs have been conserved over 175 million years, can be observed around 20 rails or tracks, one with another 147m and 142m in length.

In the Jurassic period, during the separation of continental masses - Pangea - which led to the formation of modern continents, at a time when the Earth's climate has become warmer, there were extensive shallow seas and the life was abundant, it was a tropical climate, hot and humid with dense forests.

The amount of vegetation allowed the proliferation of herbivorous dinosaurs such as sauropods. In their journeys, these animals left their footprints in the thin layers of lime mud in the lagoons existing marine shallow. After the mud dried up and was buried by limestone sediments that eventually turn into rock. After about 175 million years of exploration work of the stone allowed to lay bare the various tracks visible in the slab.

The impressions we can observe this natural monument produced by sauropods, date from the Middle Jurassic, Bajocian-Bathonian age, the animals were mighty sauropods, herbivorous quadruped, with small heads and long tail and neck. The tail would possibly defend themselves from predators, the neck, as the tail, these animals help maintain balance, allowing them to reach the taller vegetation and make them more competitive with smaller animals.
