Dr. François Therrien explores the evolution of birds’ wings in this week’s Speaker Series
Speaker Series continues this Thursday as Dr. François Therrien, Curator of Dinosaur Palaeoecology, entitled “How Did Birds Get Their Wings? Feathered Ornithomimids from Alberta Shed Light on the Origin of Wings.”
The January 26 session of the 2017 Royal Tyrrell Museum’s Speaker Series is a presentation by the Museum’s own Dr. François Therrien, Curator of Dinosaur Palaeoecology, entitled “How Did Birds Get Their Wings? Feathered Ornithomimids from Alberta Shed Light on the Origin of Wings.”
The discovery of the first feathered dinosaurs in 1998 irrevocably changed the perception of the physical appearance of dinosaurs. No longer the scaly reptiles of our imaginations, these animals were covered with feathers similar to birds. Since that first discovery, over 40 different species of dinosaurs are now known to have been covered with feathers and allow us to tackle the question: how did birds get their wings and learn to fly?
Three main hypotheses have been proposed over the years to explain the origin of wings, all equally plausible and difficult to prove. However, the recent discovery of feathered ornithomimids in Alberta offers an unexpected alternative to explain why wings first evolved.
In his presentation, Dr. Therrien will highlight these ornithomimid discoveries and explore their implications for the study of the evolution of wings.
The Royal Tyrrell Museum’s Speaker Series talks are free and open to the public. The series will be held every Thursday until April 27 at 11:00 a.m. in the Museum auditorium. Speaker Series talks are also available on the Museum’s YouTube channel: youtube.com/user/RoyalTyrrellMuseum.
