El Médano megarhizoliths field, Tenerife: Origin and paleoenvironmental significance

The vertical cylindrical structures that occur in El Médano (Tenerife) have had varied interpretations. The structures are about a few decimeters in diameter and may reach near 1 m high. In this paper we provide data that support their interpretation as megarhizoliths formed by roots and associated...
