I grew up in Chaozhou, a small metropolis in southern China surrounded by mountains and sea. I used to be at all times keen on dinosaurs, and after I was in highschool I arrange the primary web site devoted to dinosaurs in China.
Now, as a professor on the China College of Geosciences in Beijing, I’m additionally lively on social media, with greater than 6.2 million followers on [the microblogging website] Weibo, the place I share updates on my analysis into dinosaur fossils and footprints.
On 11 July this yr, I obtained a Weibo message from a designer known as Ou Hongtao. He had been eating within the courtyard of a restaurant in Leshan, a metropolis in southern Sichuan well-known for its historical mountains, and seen oval pits within the stone flooring. He despatched me a photograph – they had been common in dimension, and in a row. He had realized about dinosaur footprints from my weblog and wished to know my opinion.
I first instructed Ou to ship me a couple of extra photographs then determined to guide a ticket to fly to Leshan to see the pits in particular person. I contacted the restaurant proprietor, a backyard designer named Zhu Min, and requested if we might examine.
She instructed me that the courtyard was utilized by the earlier homeowners to lift chickens, and the pits could have been the results of the sheds that had been beforehand erected there. The brand new stone flooring was dug up by the restaurant solely final yr – earlier than it had been lined in cement. My coronary heart sank. However I needed to see it for myself.
As I approached the restaurant with my analysis crew, driving alongside a really unremarkable highway, we seen extra ferns, bringing to thoughts the period of the dinosaurs. Zhu and Ou got here to satisfy us there.
I went straight to the courtyard and thoroughly approached these pits. The stone floor was mossy and slippery: I needed to take care to not fall. We had been surrounded by massive banana timber, a spring and a miniature lotus pond subsequent to a pink rock wall filled with moss.
At first, the pits regarded like strange ones you’ll discover on the aspect of the highway, the type you often wouldn’t have a look at twice. Zhu checked out me as if I used to be about to do a magic trick.
I took two laps across the yard. After cautious consideration, I knew they had been dinosaur footprints. They had been common, and shaped two columns – for the left and proper toes. The pits had two totally different shapes, one for the entrance toes and the opposite for the again toes. No pure elements might end in such a coincidence.
On the opposite aspect of the yard, I discovered one other set of tracks, although not as properly preserved. I’ve studied dinosaur footprints for a very long time and might survey prints from above, making out who they belonged to, how they walked and the sample of the path.
We had found typical Brontopodus–kind tracks, belonging to these massive plant-eating dinosaurs with lengthy necks and tails. I imagined there have been at the least two dinosaurs strolling by the water. Maybe certainly one of them sped up a bit. Zhu was very shocked. “Now,” she mentioned, “it actually appears like a dinosaur had walked by!”
The “cement overlaying” Zhu had talked about was in truth a mix of lime, clay and tremendous sand that the earlier proprietor used to pave over the stone floor. He hated the rocks, and wished a floor that allowed his chickens to stroll simply. When Zhu took over the restaurant, she wished to play with the thought of pure magnificence, and so eliminated this higher layer, revealing the footprints.
All of the mysteries had been solved and I relaxed. My crew rigorously studied and measured the footprints. Ou felt very proud, particularly after I instructed him that amateurs could make nice contributions to dinosaur research.
This was the primary time that dinosaur footprints have been present in downtown Leshan. This can be a magical land. Footprints from the smallest dinosaur on the earth – the Minisauripus, measuring from 1cm to 3cm – have been present in rural Leshan in addition to South Korea. There have additionally been prints discovered deep in a cave from the Tang dynasty in Sichuan province.
I instructed Ou to proceed to seek for dinosaur footprints, and requested Zhu to guard the footprints in her restaurant. I hope they’ll turn into a landmark, so the youngsters of the town will know dinosaurs as soon as walked by their again yards.
