Warsaw: Hundreds of dinosaur footprints, so well-preserved that even the scaly skin can be seen, have been found in Poland, giving an insight into a complex ecosystem around 200 million years ago, geologists said.
Described by the Polish Geological Institute-National Research Institute as a treasure trove, the fossilized tracks and bones were found in an opencast clay mine in Borkowice, 130 km (80 miles) south of Warsaw.
"In the traces left by dinosaurs, you can read their behavior and habits... we have traces left by dinosaurs running, swimming, resting and sitting," said geologist Grzegorz Niedzwiedzki.
The largest footprints of carnivorous dinosaurs are 40 cm long and in many cases the skin can be seen in detail.
"In order for such a state of preservation to be possible, a very special sequence of events had to take place in a short time," geologist Grzegorz Pienkowski said in a statement.
Several hundred dinosaur tracks, representing at least seven species, have been found and geologists say they are likely to find more. They have also discovered bone fragments from animals and fish.
