This fossil tree, petrified wood of Dipterocarpus, family of magnolias, native of Java, is very particular. One can think that it has undergone a physical stress, like many: pressure, which altered its shape (ovalisation) and to the point of mishandling the periphery (two hollows on both sides, traces of hard bodies?) to create a vacuum and cause a cracking (barely visible) which allowed the liquid to penetrate to the heart. The central part of the tree began to disintegrate. The liquid has broken it down into small pieces, but in a slightly rounded shape, forming a jigsaw puzzle in which no pieces seem to be missing. These events took place during the wood-tree period. A silica gel flux penetrated into the mineralized interstices of the stone tree, into the destroyed rings, filling them with chalcedony in successive phases according to a rhythm of invasion-shrinkage, with a slightly different coloured composition each time, hence these shades in all the opalised zones, sometimes with incredible transparencies of the material. The periphery represents remarkable details: a fresco of trees, stylized trees, taking root in yellow earth, peripheral and regular penetration of a composition rich in iron. The tree forms a forest. This Cenozoic tree fossil wood is 15 to 20 million years old and its back is reinforced with fiberglass.
Really good condition
