A completely new family of rodents, a kind of rat has been found in Laos. The animal has long whiskers, stubby legs and a tail covered in dense hair and was on sale in a hunters’ market. Dr Robert Timmins working with the Wildlife Conservation Society in Thailand saw that it was probably unknown to science and brought it to the attention of his colleagues. “It was for sale on a table next to some vegetables,” said Dr Timmins. “I knew immediately it was something I had never seen before.” “To find something so distinct in this day and age is just extraordinary. For all we know, this could be the last remaining mammal family left to be discovered,” Dr Timmins said.
