Very large petrified deciduous tree, wood slice, magnolia from Java

A very large petrified deciduous tree wood slice from Java, Indonesia, palaeobotanically identified as Magnolia. The cross-section shows the typical angiosperm anatomy of a tropical Tertiary tree.

Magnolia fossils from Javanese deposits document Tertiary tropical forests that were covered by volcanic ash approximately 5 to 15 million years ago. Silicate-rich groundwater replaced the organic matter molecularly with quartz and agate over millennia. The angiosperm structure is preserved one-to-one.

The Magnolia identification increases the scientific value beyond generic silicified wood. Distinct vascular bundles, differentiated wood tissue, mineralized color zones in red, brown, and quartz light grey.

An architectural wall or table dimension. An Indonesian museum-quality collector's item with documented Javanese tropical Tertiary provenance and top gallery classification.
