People interested in the earth’s history can observe a fossil dig first-hand next week, July 23-29, as researchers start to unearth an ecosystem that dates back 200-million years. Researchers from the Fundy Geological Museum and Dalhousie University will dig in an area near Parrsboro where five dinosaur skeletons have been discovered to date. “The preservation of so many individual dinosaurs in one spot, at one time, is a rare and important discovery,” said Tim Fedak, a research associate with the Nova Scotia Museum, who is leading the expedition. “These skeletons will provide new information about the diversity of dinosaurs living during a time of great ecological change, which followed the mass extinction event at the end of the Triassic period.” Mr. Fedak said he hopes to unravel the mystery of how and why these animals died with clues from the sandstone sediments that entomb the bones. The extent of visible material will determine the course of future digs. Previous expeditions have revealed that these long-necked, long-tailed, prosauropod-type dinosaurs are cousins to American Prosauropods from the Connecticut Valley in the 1800s. The Nova Scotia animals belong to a new species that will be named in the coming year. Nova Scotians and visitors to the area are invited to take part in geological tours of the site, which will be led by Fundy Geological Museum staff from July 24 to July 28.
