fossil wood
Fossil wood is wood that is preserved in the fossil record. Over time the wood will usually be the part of a plant that is best preserved (and most easily found). Fossil wood may or may not be petrified. The study of fossil wood is sometimes called palaeoxylology, with a "palaeoxylologist" somebody who studies fossil wood. The fossil wood may be the only part of the plant that has been preserved, with the rest of the plant completely unknown: therefore such wood may get a special kind of botanical name. This will usually include "xylon" and a term indicating its presumed affinity, such as ''Araucarioxylon'' (wood of ''Araucaria'' or some related genus), ''Palmoxylon'' (wood of an indeterminate palm), or ''Castanoxylon'' (wood of an indeterminate chinkapin). ==Types==
