Alberta Sewer Dig Yields Dinosaur Bones

Wednesday, August 25, 2010

Edmonton workers discovered last week the bones of three dinosaurs while digging a new sewer tunnel. The dinosaur bones were found 120 feet (30 meters) underground by diggers Aaron Krywiak and Ryley Paul, who initially saw a sharp white tooth.

It turned out the bones were that of an Albertosaurus and two Edmontosauruses. The former is a carnivore that stood on two legs, while the latter is a four-legged herbivore.

An Albertosaurus was related to the Tyrannosaurus rex or T-Rex, which roamed the earth 75 million years ago. The Edmontosaurus belonged to the same period, and was often preyed on by the T-Rex.

According to Don Brinkman, director of preservation and research of Alberta’s Royal Tyrrell dinosaur museum, there are a lot of dinosaur bones the two diggers uncovered. The museum’s paleontologists took over the construction site and announced the bone find on Monday.

The Royal Tyrrell Museum, although only a quarter of a century old, is considered Canada’s paleontological authority.

The institution observed its 25th anniversary on May 22 with the Alberta Unearthed exhibit, which featured 25 of the museum’s most significant specimens.

Among those featured in the exhibit were a T-Rex bone discovered by two high school students on a fishing trip, a layer of fossilized plant found by a Denver scientist and theropod foot bones discovered near Manyberries by Dr. Philip Currie.
