Robot recreates the walk of a 290-million-year-old creature

The four-legged Orabates pabsti lived much before the dinosaurs.
Scientists have used a nearly 300-million-year old fossil skeleton and preserved ancient footprints to create a moving robot model of prehistoric life.
Evolutionary biologist John Nyakatura at Humboldt University in Berlin has spent years studying a 290-million-year-old fossil dug up in central Germany’s Bromacker quarry in 2000.
The four-legged plant-eater lived before the dinosaurs and fascinates scientists “because of its position on the tree of life,” said Mr. Nyakatura
