Product information "Fossil wood, 4x6 cm"

Very nice fossil wood disk, polished.

Age: Triassic
Locality: Madagascar
Size: 4 x 6 cm

Araucarias are conifers with hard, pointed, blade-shaped leaves. Today they are only found in South America and Oceania, which is a relic of their distribution on the southern primeval continent of Gondwana, which later split into South America, Africa, India, Antarctica and Australia.

The wood fossilized by being saturated with siliceous water in the absence of oxygen. The silica precipitated in the interstices as quartz, chalcedony or opal and replaced the wood, which was slowly decomposed by anaerobic bacteria. The coloration was provided by other minerals in the water, mostly iron oxides.

They are nowdays only found in South America and Oceania, which is a relic from the time they were spread over the entire ancients southern continent of Gondwana (the remnants of which are now, South America, Africa, India, Antarctica and Australia).The wood petrified by way of silica permineralisation, also know as silicification. When the wood is deposited in an anoxic environment, it usually coalifies. But if at the same time it is inundated with mineral waters (very often volcanically sourced, the precipitated silica fills out the the cavities in the wood and then tparts that get slowly decomposed by anaerobic bacteria.The picture is a sample. You will get a similar specimen.
