Scientists have found evidence of the existence of a giant cloud rat.
Modern-day cloud rats can be found in forests in the Philippines. They live in treetops which is where they get their name from.
However, this new cloud rat is twice the size of grey squirrels. Researchers discovered fossil remains of the creatures in Callao Cave in the town of Penablanca in Cagayan, Philippines.
They examined their bones and teeth to find out more about their size and shape. They believe they were large, fluffy and with big bushy tails.
Some of the remains of the rat were found in the same layer where the human fossils was discovered, making them nearly 70,000 years old!
Researchers say it means the ancient giant cloud rats could have been around for at least 60,000 years.
