A team of scientists from the University of Padova report that deforestation has revealed what could be a giant impact crater in Central Africa. The circular feature is 36-46 kilometers wide; there are only about 25 terrestrial impact craters of comparable size or larger known to exist. The object causing the crater is estimated to have been about 2 kilometers in diameter, and the date of the event appears to post-date the Jurassic Period.
