At Raiyoli, near Balasinore, is one of the 3 largest dinosaur sites of the world. Around 86 kms from Ahemedabad, experts believe Balasinore to be a major hatchery for dinosaurs nearly 65 million years ago.
This site, a treasure trove of fossils, unfolds the life of the dinosaurs which lived here. They must have been nearly 20 meters long. Numerous eggs too have been found here during excavations.
The geological studies of the region, have made the scientists believe this site to be the largest breeding grounds of the dinosaur which was destroyed by a meteorite and subsequently by volcanoes. This site is believed to be a part of the Shiva crater caused millions of years ago by a meteor from what is now eastern Gujarat to the coast off present day Bombay.
