Scientists have confirmed that an approximately 500 million-year-old stromatolite was recently discovered at the Boxley Blue Ridge Quarry near Roanoke, Virginia. This is the first-ever intact stromatolite head found in Virginia, and is one of the largest complete “heads” in the world, at over 5 feet in diameter and weighing over 2 tons. Stromatolites are among the earliest known life forms, and are important in helping scientists understand more about environments that existed in the past.
