Miller's grizzled langur was thought to be extinct, but scientists in Borneo captured images of creature using camera traps. The scientists were baffled to find the Miller's grizzled langur in an area well outside its previously recorded home range. With virtually no photographs of the species in existence, the scientists faced a challenge to confirm their suspicions, Brent Loken, a PhD student at Simon Fraser University in Canada and one of the lead researchers, said. The only images available were museum sketches like the one above.
