“Everybody got real excited, as you do,” said Peters. “I love watching kids when they find a fossil and they’re taking it out of the ground, you can just see their eyes are lighting up.”
Bruno Costa saw the light in Walter’s eyes that day.
Costa is a PhD student at the University of Manitoba’s earth sciences department studying paleontology and geochemistry.
He’s trying to decipher through rock and fossil analysis what life was like for the many marine dinosaurs, birds, sharks, fish, turtles and other creatures of ancient local ecosystems, including along the Manitoba Escarpment.
