Summary[edit]

Description

Resin from the Holocene of New Caledonia. (public display, Field Museum of Natural History, Chicago, Illinois, USA)

Biogenic products are objects produced by ancient organisms. Many paleontologists refer to these as trace fossils, but they really aren't. Examples of fossil biogenic products include eggs, amber (fossilized tree sap), coprolites (fossilized feces), and spider silk.

The light to dark brownish-gray specimen shown here is a large mass of weathered pine sap from a koghis kauri tree, a type of araucariacean conifer. The dark orange-colored object at lower left is a cleaned specimen. Tree sap is called resin. After burial and diagenetic alteration, resin becomes resinite - commonly called amber. Copal is subfossil amber - it is transitional between resin and resinite (see examples of copal and amber elsewhere in the "Fossil Biogenic Products" photo album).

Classification: Plantae, Pinophyta, Pinopsida, Pinales, Araucariaceae, Agathis lanceolata (also known as Salisburyodendron lanceolata)

Locality: unrecorded/undisclosed site in New Caledonia, southwestern Pacific Basin
