A dugout or dugout canoe is a boat which is basically a hollowed tree trunk. Other names for this type of boat are logboat and monoxylon. Monoxylon (pl: monoxyla) is Greek -- mono (single) + xylon (tree) -- and is mostly used in classic Greek texts. Some, but not all, pirogues are also constructed in this manner. Dugouts are the oldest boats archaeologists have found. In Germany they are called Einbaum (English translation: One tree). This is probably because they are made of massive pieces of wood, which tend to preserve better than, e.g., bark canoes. Einbaum dug-out boat finds in Germany date back to the Stone Age. Along with bark canoe and hide kayak, dugout boats were also used by indigenous peoples of the Americas.
