Sigiswin

Sigiswin is a fossilized track site of dinosaur footprints located in the Sables du Marne geological formation in France. The site was discovered in the 19th century and has been the subject of extensive geological and paleontological study.

The Sigiswin site is of particular interest due to the numerous and well-preserved dinosaur tracks it contains. The tracks are attributed to various herbivorous and carnivorous dinosaurs, including those of the sauropod, theropod, and ornithopod groups. The presence of these track types suggests that the site was a point where many different species of dinosaurs crossed a shallow lake or river.

Geologists have dated the Sigiswin site to the early Cretaceous period, specifically to the Aptian stage. This period, which occurred around 125-113 million years ago, is known for the diversification of dinosaurs. The fossilized tracks found at Sigiswin are significant in providing evidence of the behavior and ecosystem of these early dinosaurs.

In the study of paleontology, Sigiswin provides valuable information on the foot morphology of various dinosaur species. The site's trackway patterns and depth suggest that the dinosaurs which created them walked in a single file, and possibly exhibited gait patterns distinct from those of modern animals. Further analysis of the tracks at Sigiswin has also shed light on the environments in which these early dinosaurs lived, including indications of coastal and lacustrine habitats.
