Overview

This is a fossilized colony of rugose coral, an extinct order of coral that served as the primary reef-builders of the Paleozoic era.

Story

Four hundred million years ago, the ground you are standing on was likely a warm, sun-drenched tropical sea teeming with life long before the first dinosaur ever took a breath.

Maker / Origin

The 'makers' here were millions of tiny soft-bodied polyps, each a master architect that secreted a limestone skeleton to protect itself.

Condition & Value

The specimen shows natural weathering consistent with being found in a field or riverbed. The corallite structures are well-defined and not overly eroded, though some matrix (surrounding rock) remains attached. This raw state is preferred by many scientific collectors over polished decorative versions.
