Holocystis elegans Fossil Coral Cretaceous Isle of Wight Atherfield Specimen

Description

Holocystis elegans Fossil Coral from the Isle of Wight

This exceptional specimen of Holocystis elegans fossil coral originates from the Perna Bed within the Atherfield Clay Formation at Atherfield Point, Isle of Wight, UK. Dating to the Lower Greensand Group of the Early Cretaceous period, this fossil represents a beautifully preserved example of ancient coral life from approximately 130 million years ago. Discovered by our experienced team members Alister and Alison and expertly cleaned, prepared, and treated by Alison, this fossil is presented in its natural form with excellent detail. The photograph provided shows the exact specimen you will receive.

Geological Setting – Atherfield Clay Formation, Lower Greensand Group

The Atherfield Clay Formation is part of the Lower Greensand Group, a sequence of marine sediments deposited during the Early Cretaceous. The Perna Bed is a distinctive fossil-rich horizon within this formation, known for its abundance of marine fossils including bivalves, corals, and other invertebrates. These sediments were laid down in a shallow marine environment influenced by fluctuating sea levels, where fine silts and clays allowed for the preservation of delicate skeletal structures.

Atherfield Point is one of the most important coastal exposures of this formation in the UK, offering insight into early Cretaceous marine ecosystems and the organisms that thrived within them.

Fossil Type and Species Significance

Holocystis elegans is a fossil coral species belonging to a group of early scleractinian corals, the same broad group that includes modern reef-building corals. These organisms played an important role in marine ecosystems, contributing to the development of reef structures and providing habitat for a wide variety of marine life.

Fossil corals such as this provide valuable information about ancient sea conditions, including water temperature, clarity, and chemistry. Their presence within the Perna Bed indicates a marine environment capable of supporting complex benthic communities.

Morphological Features and Structure

This specimen displays the characteristic skeletal structure of Holocystis elegans, with a compact and often subtly patterned surface. The coral skeleton is composed of calcium carbonate and may show internal structures such as septa and growth patterns depending on preservation. These features reflect the biological growth of the coral colony and its adaptation to environmental conditions.

The fossil retains a strong three-dimensional form, with natural texture and detail that highlight its organic origin. Subtle surface patterning and structural definition make it an attractive and scientifically interesting specimen.

Depositional Environment and Preservation

The Perna Bed represents a shallow marine setting where organisms were periodically buried by fine sediment, allowing for excellent preservation. The relatively low-energy conditions prevented significant disturbance, enabling delicate coral structures to remain intact. Over time, mineralisation preserved the coral skeleton, resulting in a durable fossil with retained detail.

Fossils from this horizon are particularly valued for their clarity and their association with a well-defined stratigraphic layer, adding geological context to each specimen.

Discovery, Preparation, and Provenance

This fossil was discovered by Alister and Alison at Atherfield Point, a location renowned for its rich fossil heritage. Following collection, the specimen was carefully cleaned, prepped, and treated by Alison to stabilise and enhance its natural features. This direct provenance ensures authenticity and adds collector value through traceable origin.

Authenticity and Certificate of Guarantee

This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee card. Each piece is handled with care to preserve its natural condition, ensuring you receive a high-quality and authentic fossil.
