Intact lizard corpses in fossils found in Liaoning, China, reveal the habit of swallowing the prey of ancient 4-wing dinosaurs.
Researchers discovered fossils of a new lizard species in the four-winged ancient dinosaur belly called microraptor . Named Indrasaurus wangi, lizard fossils were found almost intact. The lizard was swallowed whole from head to tail. This is an important clue that provides information about the four-wing dinosaur's meat-eating habit.
"The new lizard has a different tooth than any other known species from the Tropical Zone, which adds to the diversity of this animal group. The lizard is almost intact and has joints, contributing to confirming that the 4-winged dinosaur is an opportunistic opportunistic predator. They swallow up all small prey from the front end like living predators and reptiles today, "the team concluded in The report published July 11 in Current Biology.
Professor Jingmai O'Connor of the Institute of Vertebrate Paleontology and Anthropology of the Chinese Academy of Sciences and colleagues found that Indrasaurus wangi has never met teeth. This is the fourth time the whole food was found in the 4-wing dinosaur belly.
The four-winged dinosaurs have long feathers in all four limbs, which lived 122 to 125 million years ago, according to the Natural History Museum. They eat many animals and insects, have a length of 76cm and weigh 1kg. Their feathers form aerodynamic surfaces in the limbs and tails, helping them to fly.
