Basal Amphibian Indet.

In 1986, a series of ten footprints were discovered in Copiapo, two of them very poorly preserved, however
some of them can be recognized. They measure around 11 cm long and 18.8 cm in
wide, both on average. The average distance between tracks is 29.5 cm. The forelimb, at
like the posterior, it is directed forward, so that the midline is parallel to the same footprint.
The oldest tracks recorded in Chile belong to a small tetrapod, possibly a labyrinthdontid amphibian.
This habit in the Chinches formation in the Carboniferous period, about 300 million years ago.
Recently another discovery of footprints was made in the Atacama region, from the Carboniferous period, approximately 320 million years old.
These latest discoveries were made in the foothills of Atacama, where you can see, for example, rocks belonging to the Carboniferous period.
The oldest tetrapod tracks in South America and the oldest in the Southern Hemisphere.
