EONS: X48 GENUINE JURASSIC DINOSAUR FOOTPRINT / TRACK DESCRIPTION: This slab dates to the Early Jurassic period, roughly 200 million years ago, and was collected with great difficulty in Languedoc, Roussillon, France. The dinosaur that made this track was a GRALLATOR (pronounced GRAL-uh-tore) meaning 'stilt walker'. It was a herding dinosaur known only from its fossilized footprints. However, the foot of Coelophysis fit these tracks exactly, and is widely assumed to have been the maker - although it can never be proven. The following drawing of two smaller Coelophysis and a large prosauropod walking on alluvial sediment suggests the scenario when this track was made. Fossil prints are always found together with others because a lone print would not be recognizable except to the most trained eyes. This print was part of a much larger trackway comprised of many dozens of prints. Once found, that particular layer of rock can then be excavated further back into the hill to find more prints. It is dangerous, backbreaking, and time-consuming work which results in only a few tracks after a full day's labor -- if you're lucky. To highlight the print, an acetone-soluble dye was applied.
