The Morokweng crater has an estimated age of 145.0 ± 0.8 million years, placing it at the boundary of the Jurassic and Cretaceous periods. It was created by an asteroid measuring about 5-10 km (3-6 miles) in diameter. In 2006, scientists recovered meteorite fragments from the crater at a depth of 770 meters (2,500 ft). These fragments may not have been attached to the asteroid but may have trailed behind it as it entered Earth's atmosphere. They are among the oldest meteorite specimens ever found on this planet.
