In geology, such fossils are referred to as either upright fossil trunks, upright fossil trees, or T0 assemblages.According to mainstream models of sedimentary environments, they are formed by rare to infrequent brief episodes of rapid sedimentation separated by long periods of either slow deposition, nondeposition, or a combination of both.
Petrified wood is found worldwide in sedimentary beds ranging in age from the Devonian (about 390 million years ago), when woody plants first appeared on dry land, to nearly the present. Petrified "forests" tend to be either entire ecosystems buried by volcanic eruptions, in which trunks often remain in their growth positions, or accumulations ...

Plant fossils from these areas tend to be endemic to the region. These include species of the fern Dicksonia, cycads Ctenis and Ctenophyllum, conifers Podozamites and Taxites, seeds of the palm Attalea, and the tree-fern Tempskya. The tree-fern fossils have been found associated with ammonites, suggesting the location of an ancient shoreline.
Fossil wood, also known as fossilized tree, 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, in which case it is known as petrified wood or petrified tree.
Liriodendron Fossils from the cretaceous and the tertiary period are found with many extinct species. Tulip Trees at one point were present in europe during the cretaceous and the early paleocene. Liriodendron Tulipifera fossils dating from the pliocene and pleistocene were discovered at the chowan formation in North Carolina.
