Maringouin Peninsula, Early reptiles

Footprint trackways from the Maringouin Peninsula record some of the world’s earliest evidence for reptiles. Rock just above and below the boundary of the Lower and Upper Carboniferous preserve footprints best identified as the trace fossil Pseudobradypus. Although it is difficult to attribute footprints to the animal that made them, traces called Pseudobradypus are thought to belong to a reptile, rather than an amphibian. Footprints found in the Grande Anse Formation show features including evidence of scales on the bottom of the feet that helped confirm their identity as reptiles.
