An article published in the journal “Nature Communications” describes the study of the fossil remains of a chick that lived about 127 million years ago and died shortly after its birth. A team of researchers led by Dr. Fabien Knoll of the University of Manchester examined this specimen that belongs to the Enantiornithes, a group of primordial birds that lived during the Cretaceous period. Its almost complete skeleton made it possible to analyze its bones’ structure and development, obtaining new data on those birds.
