Discovery of dinosaur footprints in the Stanley Pool Formation of Gabon

Stanley Pool is a Cretaceous continental formation which outcrops Southeast of Gabon to Congo. The current investigations performed in this continental formation in Gabon just revealed seven dinosaur footprints on pieces of argillites flags. The analysis of these more or less well preserved footprints highlights three morphotypes. Morphotype 1 comprises footprints 1, 2, 3 and 4 of the same shape but of different sizes. These footprints belong to tridactylous dinosaurs. Morphotype 2 comprises footprints 5 and 6 whose shape is oval. They would correspond to sauropods. Finally morphotype 3 only represented by the footprint 7 consists of four fingers. This well-preserved footprint would belong to a tetradactylous dinosaur. This major discovery is the first record of dinosaurs in Gabon. It strengthens the knowledge of dinosaurs palaeoichnology in Africa.
