Dugout canoe
A dugout canoe, or dugout is a boat that is made by hollowing out a tree. The name is sometimes shortened to dugout. Other names for this kind of boat are logboat and monoxylon. Monoxylon (μονόξυλον) (pl: monoxyla) is Greek – mono- (single) + ξύλον xylon (tree) – and is mostly used in classic Greek texts. In German, they are called Einbaum ("one tree" in English). Some, but not all, pirogues are also constructed in this manner.
Dugouts are the oldest boat type archaeologists have found. The items found date back about 8,000 years to the Neolithic Stone Age. This is probably because they are made of massive pieces of wood, which tend to preserve better than others, such as bark canoes.
