Species Overview – Coniopteris hymenophylloides

Coniopteris hymenophylloides is an extinct species of filmy fern belonging to the family Dicksoniaceae within the order Cyatheales. These delicate ferns are characterised by finely divided fronds with thin, membranous leaf structures resembling modern filmy ferns. The fossil typically preserves intricate venation patterns and segmented pinnules, offering a remarkable glimpse into Jurassic plant morphology.

This species thrived in humid, warm-temperate environments and is commonly associated with lush floodplain and deltaic ecosystems. Its presence provides valuable insight into the vegetation structure and climate of the Middle Jurassic period in what is now the United Kingdom.

Geological Context – Scalby Formation, Bathonian Stage

The Scalby Formation is part of the Ravenscar Group and is well known for its rich assemblage of fossil plants. Deposited in a fluvio-deltaic environment, this formation records ancient river channels, floodplains, and coastal swamp systems. The fine sediment layers allowed for exceptional preservation of plant material, including delicate fern fronds such as this specimen.

Fossils from this formation are highly regarded among collectors and researchers due to their scientific importance and aesthetic appeal. The Bathonian stage marks a time of significant plant diversification during the Jurassic, making specimens like this particularly desirable.

Preservation and Display Quality

This fossil has been carefully selected for its clear structure and visual appeal. The frond details are well defined, showcasing the characteristic fine divisions and venation of Coniopteris. The preparation process has enhanced contrast while maintaining the integrity of the fossil, making it suitable for both display and study.
