Fossil wood
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 fossil wood may be the only part of the plant that has been preserved, with the rest of the plant completely unknown:[28] 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)
