Xinhua/Sipa USA  by [Justin Worland](https://time.com/author/justin-worland/)  ## Justin Worland Senior Correspondent Jun 30, 2016 4:01 PM UTC Mummified bird wings from the age of [dinosaurs](http://time.com/4258240/t-rex-dinosaur-early-life/) suggest that the animal’s wings have not changed substantially since that period 100 million years ago, according to new [research](http://www.nature.com/ncomms/2016/160628/ncomms12089/full/ncomms12089.html). The [study](http://www.nature.com/ncomms/2016/160628/ncomms12089/full/ncomms12089.html), published in the journal _Nature Communications_, evaluated what are believed to be the mummified wings of bird-dinosaurs called enantiornithes. Previous research has suggested that many dinosaurs may have had feathers, but the new study provides new detail invisible in fossils based on bones, feather and tissue that remains intact. “The biggest problem we face with feathers in amber is that we usually get small fragments or isolated feathers,” says study co-author Ryan McKellar a curator at Canada’s Royal Saskatchewan Museum, [according to ](http://news.nationalgeographic.com/2016/04/160405-dinosaurs-feathers-birds-museum-new-york-science/)[_National Geographic_](http://news.nationalgeographic.com/2016/04/160405-dinosaurs-feathers-birds-museum-new-york-science/)_._ “We don’t get something like this.
