Dino Tracks Reveal Greater Variety In Grande Prairie During Cretaceous
Exciting times for everyone at the Pipestone Creek Dinosaur Initiative, as the latest discovery in the Grande Prairie region points to some amazing diversity among dinosaur populations here.
Footprints discovered in the region belong to at least four different species including meat-eaters, and a type of armoured dinosaur.
PCDI paleontologist, Dr. Phil Bell, says the unique combination of footprints and fossilized remains allows scientists to build a more complete picture of the ecology of the area at the time.
"Once we've filled in those pieces, you can start comparing those to different dinosaur faunas in the [lower] States, up in Alaska, or in southern Alberta and see how those groups of animals were changing - whether it was a response to the environment."
Bell says it's unheard of to have the combination of footprints and bones in a single region.
The findings have been published in this month's edition of 'Cretaceous Research.'
