Today, about 120 million years ago, the area found this fossil is a humid, dense forest, and the fauna is diverse from dinosaurs, birds to the ancestors of crocodiles. There are many volcanic activities in this area and periodic eruptions are buried as well as the remains of animals in this period.

Of the two pieces of fossil that scientists found, a piece of fossil was in its entirety and was well preserved, inside the stomach was another dinosaur, smaller, hairy and of the same size. cat, whose scientific name is Sinornithosaurus.

The remaining incomplete fossil contains two crow-sized birds in the stomach, scientifically known as Confuciusornis. This is a slow-flying animal that does not fly long, along with the corroded bones of other dinosaurs.

Phil Bell, a paleontologist in Canada for LiveScience, said: 'What remains in this fossil's stomach is evidence of a lively interaction between animals, which is very rare in fossils.'

It is still unclear whether this dinosaur is hunting for such meals or that they only dig for prey. But one thing is clear: they ate 2 birds at the same time. The selection of prey and capturing flying animals shows that they are stout and stalking hunters.

'A lot of people view fossils only as senseless objects, difficult to imagine their vibrancy. So when we have fossils like this, they actually blew souls into fossils , 'Bell said.
