Fossil Coral Miocene Indonesia with COA

Description

SIZE (Picture scale cube=1cm):  27 x 15 x 11mm (1.06 x 0.59 x 0.43 inches)

Fossil Coral from the Miocene – Natural Prehistoric Specimen from Indonesia

This genuine Miocene Fossil Coral from Indonesia is a beautifully preserved remnant of an ancient reef system that flourished millions of years ago. Its intricate natural patterns, visible skeletal structure, and warm earthy tones make it both a scientifically valuable fossil and an attractive display specimen. Formed during the Miocene Epoch, this coral represents a time of major global change, when tropical seas hosted diverse reef ecosystems comparable to those of today.

You will receive the exact fossil shown in the photographs. A 1 cm scale cube is included for accurate size reference. Every fossil is carefully chosen for quality, preservation, and visual appeal.

All of our fossils are 100% genuine specimens and each purchase includes a Certificate of Authenticity.

Geological Origin – Miocene Epoch, Indonesia

This fossil originates from the Miocene Epoch (approximately 23–5 million years ago), a period marked by shifting climates, expanding grasslands, and dynamic shallow marine ecosystems. During the Miocene, Indonesia was part of an extensive tropical archipelago characterised by warm, shallow seas ideal for coral growth.

These seas supported vast reef environments similar to modern coral reefs found in Southeast Asia today. Over time, coral colonies grew, died, and accumulated into thick reef structures. Subsequent burial beneath marine sediments, combined with mineral replacement processes, transformed the original coral skeleton into stone while preserving its intricate biological architecture.

Today, these fossilised corals are uncovered from sedimentary deposits uplifted through tectonic activity—Indonesia being one of the most geologically active regions on Earth.

Coral Type & Morphological Features

The fossil coral shows the classic structural characteristics of ancient reef-building corals belonging to the order Scleractinia (stony corals). These organisms constructed robust calcium carbonate skeletons composed of numerous small cup-like chambers called corallites, each once housing a single coral polyp.

Key morphological features include:

• Distinct corallite patterns, forming radiating or honeycomb-like arrangements
• Visible septa, the fine radial walls inside each chamber
• Well-preserved skeletal texture, showing natural biological growth structures
• Three-dimensional relief, providing depth and clarity to the fossil surface
• Natural mineral colours, ranging from beige and cream to soft grey or warm brown tones

These structural details offer insight into the coral’s growth habits, colonial form, and ecological role within its ancient marine environment.

Depositional Environment & Fossilisation Process

Miocene coral fossils from Indonesia typically originate from shallow marine carbonate platforms. These environments featured:

• Warm tropical waters
• Clear conditions ideal for sunlight penetration
• Abundant marine life including corals, molluscs, fish, and echinoderms
• Low sediment input, providing stable conditions for reef formation

After the coral colony died, mineral-rich groundwater gradually replaced the original calcium carbonate with more durable minerals such as silica or calcite. This permineralisation preserved the structural details while strengthening the fossil over millions of years.

The result is a solid, stone-like fossil that retains the geometry and texture of its original living form.

Scientific, Decorative & Collecting Appeal

Fossil corals are important to palaeontologists because they provide information about:

• Ancient marine environments
• Sea temperatures and water chemistry
• Biodiversity patterns in prehistoric reef systems
• Plate tectonic changes in Southeast Asia

Beyond scientific value, they are also appreciated for their natural beauty and striking patterns. This specimen is ideal for:

• Fossil and mineral collections
• Home or office décor
• Educational displays
• Photography and artistic projects
• Unique natural-history gifts
