Four-legged creatures known as dire wolves who were prominent in HBO’s “Game of Thrones” series no longer belong solely to the realm of fantasy.

Colossal Biosciences, the genetic engineering company working to bring back a few different extinct animals, announced this week the successful resurrection of the Ice Age-era species. The recent birth of three dire wolf puppies marks the first time Colossal has successfully “de-extincted” a species, the company said Monday in a press release.

Colossal, a biotech company based in Dallas, Texas, is famous for its efforts to bring back the wooly mammoth and the Tasmanian tiger. DNA recovered from a 13,000-year-old tooth and a 72,000-year-old skull is what propelled scientists at Colossal to bring back the dire wolf.
