A team consisting of a German archaeologist and two Indians discovered dinosaur fossils during an ongoing research in Gujarat.

Archaeologists claimed that the fossils found in the Kaas Hills near Kutch city dated back billions of years.

They also claimed to have discovered more than 150 geological sites adding it might be possible to find more fossils and other ancient relics in the future.

"We are getting the fossils of dinosaurs from the time when dinosaurs lived in the coastal areas. This couldn't be found earlier. 15 years ago, we had collected fossils, then the ONGC (Oil and Natural Gas Corporation) collected fossils of dinosaurs. And now again, we have discovered the fossils of the dinosaurs," said an archaeologist, DK Pandey.

The scholars were researching on the possibilities of ancient fossils in the Kutch city for the last 25 years.

One of the largest dinosaurs ever found was in 2014 in Argentina's Patagonia region, where titanosaurs roamed the forests about 100 million years ago.

Birds evolved from small feathered dinosaurs. The oldest-known bird, warm blooded, crow-sized Archaeopteryx, lived about 150 million years ago.

The researchers had earlier evaluated the metabolism of 21 dinosaur species using a formula based on their body mass, as revealed by the bulk of their thigh bones, and their growth rates, indicated by growth rings in fossil bones akin to those in trees.
