Paleontologist Robert Reisz is the featured guest of the seventh annual Earth Day Dinner, a fundraising event for Canada South Science City, on Wednesday, April 25.

In his talk, “The Oldest Dinosaur Eggs, Embryos, Nests, and Babies: What They Teach Us about Dinosaur Biology and Evolution,” Dr. Reisz will describe discoveries made with his colleague David Evans of the Royal Ontario Museum and their team in Africa.

The nesting sites they found were 190 million years old, dating back to the earliest dinosaurs and over 100 million years older than previously discovered dinosaur nests. The fossils indicate that the massospondylus dinosaurs, ancestors of the brontosaurus, nested in groups and raised their young with care.

Reisz, a biology professor at the University of Toronto Mississauga, is a fellow of both the Royal Society of Canada and the American Association for the Advancement of Science, and an honourary member of the Society of Vertebrate Paleontology.

The dinner, co-sponsored by the UWindsor Faculty of Science, starts at 6:30 p.m. at the Caboto Club, 2175 Parent Avenue. Tickets are $35 each or $250 for a table of eight – a portion is a tax-deductible donation. For tickets or more information, call the science centre at 519-973-3667.
