The only specimen of Microraptor has been collected at the Jiufotang Formation deposits near Jianchang in the Province of Liaoning, north-east China.
In the early Cretaceous terrestrial and freshwather ecosystems in a multi-layered rock formation, Liaoning, Hebei and Inner Mongolia, Chinese provinces and famous for their extraordinarily well-maintained remains of early birds and feathered dinosaurs, primitive mammals, and ancient plants, were both the dinosaurs and the lizards. This is the so-called Jehol Biota.
“This is the fourth documented occurrence of a Microraptor preserving stomach contents,” said Professor Jingmai O’Connor from the Institute of Vertebrate Paleontology and Paleoanthropology at the Chinese Academy of Sciences and colleagues.
“This dinosaur is now known to have fed on mammals, birds, fish, and lizards, supporting the interpretation that it was an opportunistic predator.”
Indrasaurus wangi is the lizard had teeth unlike any other previously known from the Jehol Biota.
The skeleton of the creature is almost full and articulated, demonstrating that it was swallowed whole and head first, meaning that Microraptor was fed in a way comparable to living carnivorous birds and lizards.(source)

Microraptor and a snack. The cool thing about exceptional preservation in localities like jehol is that not only do we have amazing snapshot of what the animals looked like but also the actual interactions of these animals is preserved. In this case predator and prey. #sciart pic.twitter.com/9tTC2cymsR
