Finding the longest set of footprints left by the first vertebrate

BBC World Service - Witness History, Finding the longest set of footprints left by the first vertebrate

In 1992 a student found a set of fossilised footprints from the earliest vertebrate

While he was mapping rock formations in County Kerry, Ireland, Iwan Stössel stumbled across fossilised footprints from a tetrapod made 385 million years ago.

In 1992 off the coast of Ireland, a Swiss geology student accidentally discovered the longest set of footprints made by the first four-legged animals to walk on earth.

They pointed to a new date for the key milestone in evolution when the first amphibians left the water 385 million years ago. The salamander-type animal which was the size of a basset hound lived when County Kerry was semi-arid, long before dinosaurs, as Iwan Stössel explains to Josephine McDermott.
