Analyse d'un exemple de fossilisation d'une trace de pas de Dinosaure (Lias inférieur des Causses)
(2003)
A calcareous block made of algo-laminated (stromatolitic) material exhibits at its upper surface a foot print of a Dinosaurian. A vertical section (sawing) and a thin section allow to make detailed observations. The early diagenesis permits the preservation of the deformations caused by the foot print.
