Abstract: Abstract:The Bruneau Woodpile site has long been popular among fossil collectors; however, the deposit has received scant attention from scientists. Our research reveals that the fossilized wood was deposited ca. 6.85 Ma, within the Chalk Hills Formation, and was mineralized with carbonate-fluorapatite. The diverse assemblage of conifers and hardwoods is representative of the warm temperate forests that flourished in southwest Idaho, USA during the late Miocene. Limb and trunk fragments preserved in a single t… Show more

“…Research from other regions provides abundant examples of petrified wood that was resulted from multiple episodes of mineral deposition [49,[63][64][65][66][67][68][69]. At Meshgin Shahr Fossil Forest, mineral features suggest that the following processes were involved in wood petrifaction:…”

“…In both specimens, the presence of these minerals is evidence that cell interiors (lumen) remained open after the cell walls had been mineralized with opal. Calcium phosphate has previously been reported as a major constituent in fossil woods that range in age from Carboniferous to Holocene (summarized by [69]), and as a minor constituent of Eocene carbonized wood in Eocene wood from California, USA [70]. The precipitation of calcium phosphate is favored by the presence of dissolved Ca and P, and low pH that favors the precipitation of Ca 5 (PO 4 ) 3.…”

“…Abundant phosphatized wood in Miocene lakebeds at Bruneau, Idaho, USA are homogeneous in composition, consisting of carbonate-fluorapatite [28]. At this locality, fossilized driftwood ( Figures 4B and 5A) occurs within a single thin sandstone bed that was deposited as a cataclysmic debris torrent [28].…”
