[A frog from 100 million years ago, what was in its stomach?] Paleontologists from China and the United Kingdom jointly announced on the 23rd that they had found rare frog stomach fossils in Inner Mongolia. The owner of the stomach is the 120 million-year-old Gurney frog, the body length is about 7.5 cm, the skull length is 2.4 cm, and in its stomach volume, the salamander skeleton is clearly visible, preserving the skull, spine and part of the front and back limbs, and the distal end of the tail is not preserved. "The salamander skeleton in the specimen is articulated together and is largely intact, indicating that it was swallowed by the frog in its entirety; and depending on the position of the skeleton, the salamander's tail is likely to remain outside the frog's mouth—that is, buried the moment the frog swallows the salamander." One of the researchers of the discovery @ Xing Lida described.
