New bird-like dinosaur fossil found in China with frog stays in its abdomen

Scientists have unearthed a bird-like dinosaur that lived about 120 million years in the past in modern-day China with the partial skeleton of an historical frog within the stays of its intestine.

Researchers, together with these from the Chinese language Academy of Geological Sciences, say the dinosaur named Daurlong wangi was a sort of mid-sized dromaeosaurid – a bunch of bird-like predatory dinosaurs.

This species, scientists say, primarily ate up fish, mammals, and different dinosaurs.

The dinosaur lived throughout the Early Cretaceous interval, about 145 to 100 million years in the past (mya) in Jehol Biota, a freshwater ecosystem in what’s at present northeastern China, in line with the research, printed within the journal Scientific Experiences.

Within the stays of the dinosaur, researchers additionally discovered a “giant bluish layer” within the stomach, representing one of many few occurrences of intestinal remnants amongst such dinosaurs.

“Dromaeosauridae is a clade of small- to mid-sized theropod dinosaurs identified from the Cretaceous of each hemispheres,” stated Xuri Wang from the Institute of Geology on the Chinese language Academy of Geological Sciences.

“The Early Cretaceous Jehol Biota from north-eastern China has offered a wealthy variety of dromaeosaurids, nearly all of which referred to Microraptorinae,” Dr Wang added.

Within the research, researchers described the dinosaur species based mostly on an virtually full skeleton discovered on the Pigeon Hill locality of the Longjiang Formation in Inside Mongolia.

“The holotype of Daurlong wangi is an virtually full and articulated skeleton with a size of about 1.5 m,” they stated.

Scientists additionally discovered the partial skeleton of an historical frog in its intestine contents, marking the primary case of such intestinal preservation in a dinosaur intently associated to birds.

“The reconstruction of the gastrointestinal tract in extinct species, together with dinosaurs, may very well be inferred, not directly, from intestine content material stays,” they stated.

“The Daurlong wangi specimen exhibits the primary case of intestinal preservation in a theropod lineage very near hen ancestry,” scientists added.
