The dinosaurs (terrible lizards) constitute two different groups of extinct reptiles, derived from a common ancestor and together with other groups like crocodiles, birds and other extinct reptiles, share unique anatomical features.
The dinosaurs appeared on earth during the Triassic period, 235 million years ago and continued to exist to the end of the Mezosoic (end of the Cretaceus ) era, when all of them, 65 million years ago, became extinct together with many other groups of organisms. The common explanation of this mass extinction is probably due to a massive impact of an asteroid with the face of the earth, the consequence of which was a worldwide catastrophe to life.
During most of their existence on earth (around 170 million years) the dinosaurs dominated most of the continental habitats, were wide spread all over the continents and fed on a broad spectrum of diets (from feeding on leaves to engaging a ferocious predatory behavior).Some of them became highly socialized, laid eggs in bird-like nests ad protected their youngsters. Some others achieved huge dimensions of the body-size.
Dinosaur footprints discovered in Beit Zayit are on display at the Hebrew University of Jerusalem
Related species of the same age were described from North America and Mongolia. Until now, no dinosaur bones were found in Israel, but the footprints of Beit Zait show that a band of this species ran about the shoreline of the old Tethys ocean which, at that time, covered the coasts of the Middle East.
