Photographer's Note

I have taken the picture I have chosen for this contribution in the small village of Saint Laurent de Trèves, which is one of my favourite stops along the road leading from the Southernmost part of the department of Lozère to the Gorges du Tarn area (Languedoc, South France).
In this place the curious visitor will be able to observe incredibly well preserved dinosaur footprints, outcroping in limestones which are 190 millions years old.
The example you can see in the very foreground of the picture is quite representative of the numerous ones that are present on the site (more than 20 in different locations). This one is particularly impressive as it stands, at present day, in front of the beautiful deep valley separating the plateau of "Can de l'Hospitalet" from the neighborhing "Causse Méjean". Of course, the valley was not there when the big lizards were walking around, in the muddy formations that were covering the area!!!
It is pretty difficult to get an idea about the animal which has walked there during the Hettangian period(Lower Lias), but from the size of the footprints, the palaeontologist assume that they were about 3 to 3.5 meters high and were theropods, i.e., carnivorous dinosaurs.

J'ai pris cette image dans le village de Saint Laurent de Trèves, l'une de mes haltes favorites lorsque je voyage entre le sud de la Lozère et la région des Gorges du Tarn.
A cet endroit, le visiteur curieux des choses de la nature peut observer des traces de pas de diosaures vieilles de plus de 190 millions d'années.
L'exemple pris ici est particulièrement esthétique et impressionnant car il fait face de nos jours à la profonde et belle vallée qui sépare le plateau de la "Can de l'Hospitalet" de son voisin le Causse Méjean. Bien entendu, cette vallée n'était pas là lorsque les gros lézards arpentaient la boue qui recouvrait le terrain!
Il est difficile de dire précisemment à quelle espèce appartenaient ces animaux en se basant uniquement sur leurs empreintes de pas, mais les paléontologues pensent qu'is mesuraient autour de 3 mètres ou 3.5 mètres et qu'ils appartenaient à la grande familles des théropodes, les mangeurs de viande...
