How does wood turn to stone? Petrified wood forms after a tree trunk becomes covered by wet mud composed of fine sediments or volcanic ash. Water keeps the wood from decaying quickly, and the mud provides silica that gradually replaces the wood’s cells with quartz, opal, or chalcedony (all are forms of silica). Sometimes this happens so slowly that the tree’s rings and cells are preserved. Some petrified wood can be very colorful because iron and manganese impurities can tint the silica red, yel

Deans been turning petrified wood into beautiful Toki pendants…. Did you know the petrification process occurs underground, when wood becomes buried in water or volcanic ash! #petrifiedwood #newzealandwood #p#pounamug#greenstonen#newzealandn#newzealandgreenstoneh#heitikin#nzgiftideap#pounamugiftt#teaomaorim#manaiak#kawakawak#kawakawapounamug#greenstonechristchurchs#smallbussinessn#nzcultureg#giftideasnairobi #p#pounamug#greenstonen#newzealandn#newzealandgreenstoneh#heitikin#nzgiftideap#pounamugi

Petrification is the geological process in which organic material (including wood, bone) is turned to stone slowly over time. Are all fossils petrified? No. There are also compression fossils, impressions (also known as molds), casts, and trace fossils. Is everything fossilized? No, an incredibly small percentage of life has been fossilized. Approximately less than one tenth of one percent of all species that have ever lived became fossils. #MNH #Dinosaur #Fossil Video description: still photos
