A flightless bird
Canadaga arctica was a bird, but after scientists studied its physical characteristics they found that this type of bird did not have the appropriate wing structure to support flight.
Every species on Earth has evolved to have very unique traits that make up who and what they are. At times, some of these physical traits are 'leftovers' from evolutionary ancestors who once used these features for various reasons such as the environment in which they lived or the predators they once had to escape from.
Canadaga arctica was a large bird that was around 2.5 metres in length. Living in shallow Arctic seas during a time known as the Cretaceous period, this bird had a beak and a mouth full of teeth that it used to hold prey.
A fossil date
Many Canadaga arctica fossils date to 67 million years ago, a time just before the giant extinction event that wiped out the dinosaurs.
