Bite-size clue may help rediscover the missing desert rat-kangaroo

An intriguing native Australian rat-kangaroo, thought to be probably extinct, may still be running around in the inhospitable remote Sturt Stony Desert -- and researchers have discovered new details about its feeding habits that might help to find it. The experts in marsupial evolution and ecology have compared the biting ability of different small animal skulls to understand the kinds of food the desert rat-kangaroo (Caloprymnus campestris) ate, thus narrowing down the best areas to monitor for the little animal.
