What to see
At its entrance, is a 180 million-year-old complete skeleton of an extinct marine dinosaur, the Occitanosaurus tournemirensis which was discovered fossilized in the “grey clay soils.”
The ecologically Sensitive Natural Space (SNS) of the Tournemire amphitheatre which is situated in the village of the same name, stretches over an area of approximately 130 ha and marks the boundary between the frontal causses and the causse du Larzac. This area has a remarkable environmental importance due to the geomorphology of the site and also owing to several natural habitats of European interest that it provides. This natural space shelters numerous noteworthy bird species: the Eagle Owl, the Golden Eagle, the Common Whitethroat, the Wallcreeper, the Red-billed Chough and some inconspicuous bats. A few plant species well-adapted to the topography, the rock and even sometimes to the Mediterranean climate can be observed: Hoppe's Figwort, Hormathophylla macrocarpa...
The House of Plesiosaur displays the skeleton of the marine reptile (it's a copy, the original is at Millau's museum) along with interpretative panels about the geology, Plesiosaur, flora, birds and bats. It is also the starting point of the Tournemire amphitheatre hiking circuit that enables you to immerse yourself in a unique environment and of the point of departure for the amphitheatre interpretive trail.
"Espace Nature Aveyron" is a mobile application which allows to discover the whole range of animal and plant species living in this ecosystem and to enjoy the SNS stroll.
