Scarborough,
180 million years ago

A FAMILY GROUP of sauropods, each adult the size of three African elephants, wander about chomping the cycads and horsetails, untroubled by the ostrich-sized predators, Coelophysis, running by.

 

But they’re wary of an unseen menace lurking in the undergrowth: the top predator of the day - not Tyrannosaurus rex, which wouldn’t appear until the end of the Cretaceous period 100 million years later - this is Megalosaurus, nine metres in length and weighing a ton.

Dinosaur Footprints

Tridactyl ornithopod pes.
Burniston Bay

The carnivorous theropod (middle toe longest) dinosaur that made this 35 cm long track stood 1.5 metres tall at the hip.

The theropod dinosaur that made this 16 cm long foot-print, stood 60 cm. at the hip.

Footprints from a trackway (not to scale) of a theropod, 40 cm at the hip, calculated to have been running at 15 mph.

 

 

Dinosaur delta: these cross-bedded sandstones at Scalby Mills, North Bay, Scarborough, date from the mid-Jurassic when dinosaurs roamed the subtropical forests of ferns, cycads and conifers.
