Fossil bone specimens of a living tooth bird 125 million years ago have just been discovered in China.

Archaeologists from the Museum of Natural History in Los Angeles City (USA) said the fossil was in its entirety, even the food in the stomach remained. The unusual thing is that this bird has strong teeth that can eat hard-shell insects and snails.

The aforementioned bird fossil specimen was found in Liaoning province, where many white chalk fossils have been excavated (145-65 million years ago). However, this is the first time archaeologists have discovered fossil birds.

Scientists say the bird is called the scientific name Sulcavis geeorum , which belongs to the extinct Enantiornithines.

Today's birds also carry teeth-related genes, but these genes have faded away. The discovery of this bird model helps scientists illuminate more mysteries about prehistoric birds.
