The discovery of two tiny wings perfectly preserved in amber prehistórica bird shows plumage (the layers, the employer, the provision of color and feathers) we observe today in the birds was present in some of their predecessors who lived for nearly 100 million year ± os.
a study published by Nature Communications on June 28 concluded that these wings, probably belonged to a enantiornites, a kind of avian dinosaur extinguió late CRETE cico.
“For the first time we are seeing feathers associated with materials óseos” he told Nature study co-author, Ryan McKellar, investigating fossil as curator of paleontologÃa of invertebrates at the Royal Saskatchewan Museum in Regina, Canada .
the majority of these types of fossils preserved in amber come from the mines Hukawng valley in Kachin State, Burma.
Currently, the valley is under the control of Eja © Army for the Independence of Kachin, faced in an intermittent conflict with the state for more than 50 years ± os.
Because of this conflict, the extraction and sale of amber is not regulated and most of the material is sold to Chinese consumers, who use it to create pieces of jewelry.
In fact, one of the samples enantiornites is called ‘Angel’ because a design ± ador of jewelry wanted to incorporate a slope called ‘angel wings’.
For scientists, the appeal of the samples preserved in amber is found in the fact that it contains probably the greatest variety of animal and plant life Cretácico period.
scientists emphasize the importance of finding because, they argue, will allow them to know with more precision how were these ancient birds, as the wings retain a number of intersantes details such as color patterns and accurate provision of feathers to bones.
