Could Strange Mars Craters be from a Fallen Third Moon?

Was there a third Martian moon orbiting the planet? Did Phobos and Deimos have a triplet sibling? According to the discovery of two elliptical impact craters, there might just have been another moon, but it ploughed into the Red Planet's surface a long time ago. The moonlet would have been approximately 1.5 km wide (0.9 miles), and it will have succumbed to the Mars gravity, entering the atmosphere at a shallow angle.
