Scientists found three fragments of bones —  part of the ulna and parts of the humerus — along with the bones of some vertebrates in 1996 on Axel Heiberg Island. It can often take researchers many years to study prehistoric fossils and make conclusions.
The new species was named Tingmiatornis arctica. Tingmiat means "those that can fly" in Inuktitut. 
Though the discovery allowed scientists to link the bird to its modern-day descendants, the Tingmiatornis arctica doesn't quite resemble the birds we see now.
"The bird would have been a cross between a large seagull and a diving bird like a cormorant, but likely had teeth," John Tarduno, professor and chair of the Department of Earth and Environmental Sciences at Rochester University and leader of the expedition, said in a statement.
The fossils also provide scientists with a better understanding of the climate and environment during the Cretaceous period's Turonian age, which lasted from around 93.9 to 89.8 million years ago.
Instead of a frigid icy region, the Canadian Arctic would have been more like today's Florida —  but with volcanoes. There would have been a -read more
