Elektorornis means "amber bird," and it belongs to a group of extinct birds called Enantiornithes
, the most abundant type of bird known from the Mesozoic era.
The fossil belonged to a chick that was part of a group of ancient birds called Enantiornithes
To be exact, scientists have placed the baby bird as a member of the enantiornithes, a major group of birds that existed in the Cretaceous period some 145.5 to 65.6 million years ago, reports National Geographic.
This reinforces the idea that enantiornithes birds hatched from the egg ready to fly.
Other Mesozoic groups like Enantiornithes
, which had teeth and clawed wings, are not thought to have left any living descendents.

The bird, part of an extinct group called Enantiornithes, was found inside an early Cretaceous winged theropod called Microraptor gui.
"The fact that Enantiornithes are largely viewed as arboreal animals doesn't mean that they didn't frequent the ground - like most living arboreal birds, from parrots to woodpeckers," the New Scientist quoted Luis Chiappe at the Natural History Museum of Los Angeles County as saying.
