“All this weather is revealing traces of vanished worlds along our coastline,” the group wrote on their Facebook page .
“Shifting sands at Sandown Bay revealed this beautiful 139 million year old dinosaur track yesterday, preserved in the brightly colored floodplain clays. ”
The group, which runs tours of the area, said that the footprint was preserved in what would have been an area of marshland that regularly dried and flooded.
“Our track maker was crossing this environment 161 million years ago, heading southwest in what is now Sandown Bay, leaving these huge tracks in the boggy soil, ”they wrote.
“Behind the animal lay a range of low forested hills, while ahead lay a flat floodplain landscape dotted with floodplain forests, river channels, and herds of herbivorous dinosaurs . ”
However the footprint may soon disappear as the tide wears down the soft clay on what is known as the “Wessex Formation”.
Violent storms along the south coast have previously revealed a large number of dinosaur footprints near Hastings, East Sussex .
Those tracks included a species of stegosaur, the armored ankylosaurus and predatory theropod dinosaurs.
