An excavating team in Argentina have unearthed a rock weighing over 30 tonnes it is thought could be one of the world’s largest meteorites.<br /><br /> It was unearthed from an area 1,000 kilometres north of Buenos Aires that is littered with craters and is believed to have experienced a powerful meteorite shower more than 4,000 years ago.<br /><br /> Scientists are to carry out more tests to determine the rock’s origins.<br /><br /> The same area of Argentina – Campo de Cielo – is home to another giant meteorite known as El Chaco. Weighing 37 tonnes, it was discovered in 1969.<br /><br /> The world’s largest was found in Namibia nearly a century ago. Hoba weighs more than 60 tonnes and is said to have landed 80,000 years ago.<br /><br /> Astronomers say they were surprised by the latest discovery’s size and weight. <br /><br /> The readings need to be confirmed but scientists are confident: an estimated 100 tonnes of space debris have been excavated from the site so far.<br />
