Summary

[edit]
Description
English: 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.

Some modern trees release relatively copious amounts of resin (sap), which is a potential precursor to copal and amber.

Locality: forest at Nethers Flint Quarries, eastern end of Flint Ridge, east-central Ohio, USA
