marks are fossilized traces of the way water has shaped the bottom of
shallow lacks or wide rivers. Big stretches of ripple marks (100 m2
or more) can be found in excellent condition in south Jordan. These
ripples of the Mudawwara Formation in southern Jordan are from the Ordovician
period (500 - 440 Million years).
