Unable to compete with other tree-dwelling dinosaurs and early birds, they went extinct after just a few million years.</p> Wed, 21 Oct 2020 19:49:44 +0000 shirley.cardenas@mcgill.ca 244354 at /newsroom /newsroom/channels/news/ctv-news-some-dinosaurs-were-flying-there-were-birds-new-research-suggests-323691 <p>Biologists now have a better idea of the origin of birds and the evolution of flight, two iconic events in the history of life on earth, thanks to work by a group of international scientists including a 91ÉçÇø professor. In updating the evolutionary tree, the team’s findings show some dinosaurs could fly before they evolved into birds, and many others were experimenting with powered flight.</p> Thu, 13 Aug 2020 23:28:35 +0000 amelia.souffrant@mail.mcgill.ca 233899 at /newsroom /newsroom/channels/news/t-rex-was-champion-walker-super-efficient-lower-speeds-322130 <p>While smaller dinosaurs needed speed, huge predators like T. rex were optimized for energy-efficient walking, according to a <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0223698">study</a> published in PLOS ONE.</p> Wed, 13 May 2020 18:19:54 +0000 amelia.souffrant@mail.mcgill.ca 210711 at /newsroom /newsroom/hans-larsson Thu, 19 Dec 2019 19:35:06 +0000 Anonymous 23362 at /newsroom /newsroom/spotlight <p><img height="240" width="160" style="float: right;" class="media-element file-default rt" src="/newsroom/files/newsroom/styles/wysiwyg_medium/public/channels/image/img_1154_copy.jpg?itok=i2YzRwbK" alt="" /></p> Tue, 13 May 2014 20:22:19 +0000 laurie.devine@mcgill.ca 20741 at /newsroom
