Ancient crocodile bones discovered in Xi'an

Ancient bones unearthed in Xi'an, capital of Shaanxi province, have led archaeologists to suggest that the area may have been home to wild crocodiles thousands of years ago.

Experts have been excavating the Haojing site since the 1930s, with the latest dig running from 2012 to last year.

The site was once the capital of the Western Zhou Dynasty (c.11th century-771 BC), with countless relics having been discovered there over the years. However, the ancient crocodile bones took archaeologists by surprise.
