After 90 years gathering dust, B.C. dinosaur bones identified as belonging to club-tailed species

Bones unearthed90 years ago in northeastern B.C.have finally been identified asthe95-million-year-oldremnants of anankylosaurian dinosaur a group of animals known to have tail clubs.

"It's the first record of dinosaur bones from this particular group of dinosaurs in British Columbia," saidVictoria Arbour,who led work to identifythe fossils.

Arbour, curator of paleontology at the Royal B.C. Museum, said this also marks the first time dinosaur bones from this era were discovered in B.C.

The fossils were originally found in 1930 along the Pine River, near Chetwynd, in the province's northeast region.

The rib and two broken vertebrae come from a stocky, four-legged dinosaur with bony plates and spikes. Some ankylosaurian species are known for thedistinct ball of bone at the tip of their tail called a 'tail club,' said Arbour.

The long-overlooked fossils are currently part of the Canadian Museum of Nature's collection.

"The work of Dr. Arbour and her peers in this paperreminds us of the central role played by museum collections, the source of exciting new discoveries even decades after specimens are acquired," said Jack Lohman, CEO of the Royal B.C. Museum, in a news release.

So, how did they determine that these fossil bones came from an ankylosaur?

"It all has to do with the rocks that they come from," said Arbour. "This is why when fossils are collected, it's so important to note down where exactly they were found with as much detail as possible."

Ankylosaurian footprints had previously been found in the Peace River region. Arbour hopes this latest revelation means there are more bones to be discovered in the area.
