Dinosaurs left lasting footprints only when conditions were just right, scientists have claimed.University of Manchester researchers used computers to simulate prehistoric creatures making tracks in different types of mud.They found that soil conditions had to be perfect for different dinosaurs to leave fossil footprints behind.Dubbed the "Goldilocks effect", scientists say it explains why tracks were left at some sites and not others.
The Fondazione Bruno Kessler in a collaborative project with the Natural History Museum of Trento to digitally collect dinosaur footprints(by Marzia Lucianer)Throughout Trentino, there are many signs left by the giants that trod the beaches which, millions of years ago, and even before the valleys were formed, once dominated the landscape here - the dinosaurs. Icnologists - scientists who study the traces of animal behaviour - have long been trying to discover more about the types of animals that once roamed the earth.
Staff at the Morrison Natural History Museum have again discovered infant dinosaur footprints in the foothills west of Denver, Colorado, near the town of Morrison. Dating from the Late Jurassic, some 148 million years ago, these tracks were made before the Rocky Mountains rose, when Morrison was a broad savannah full of dinosaurs.

Scientists in China say they have discovered more than 3,000 dinosaur footprints, all facing the same way.The footprints - thought to belong to at least six dinosaur types - were found in eastern Shandong province, state news agency Xinhua reports.Experts believe the prints are more than 100 million years old and say they could represent a migration or a panicked attempt to escape predators.
Around 300 dinosaur footprints believed to be around 65 million years old were lost when the rock wall that contained them cleaved off and crumbled, a Bolivian national park director said on Wednesday.Parque Cretacio director Wilmer Astete told ATB television that heavy rain and seismic instability had weakened a slab of rock measuring 80 metres in Cal Orcko.
Dinosaur footprints formed 165 million years ago on an ancient shoreline in north Oxfordshire are to be given special protection by the Government's conservation experts, Natural England.The fossilised tracks of dinosaurs including the Brachiosaurus, a vegetarian, and the carnivorous Tyrannosaurus are in a working quarry at Ardley, near Bicester, close to the M40. It is to be designated a Site of Special Scientific Interest - the first to be protected for its geological features alone.
