Indonesian Red Copal (Subsoil to Surface Horizons, Late Holocene)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
This specimen weighs 36.0g and measures 65x40x25mm; several small fragments of plant material are contained within its translucent, reddish mass. Originating from the island of Java, this variety of copal is a fairly recent discovery; it is recovered from various soil levels, near to or on the surface of the rainforest floor. Rough specimens usually exhibit a thick, whitish exterior crust; Indonesian red copal is very soft, reacts readily with acetone, and can be scratched with a fingernail. -
