Description
Fossil Plant – Acrostichopteris (ruffordi) Pinna
Geological Period: Early Cretaceous (Wealden Group)
Age: Approximately 140 to 125 million years ago
Formation: Weald Clay Formation
Locality: Ecclesbourne Glen, Hastings, East Sussex, UK
This listing features a fine and detailed fossil fern pinna of Acrostichopteris ruffordi, a species of prehistoric vascular plant that flourished in lowland floodplains and swampy environments during the Early Cretaceous. Collected from the historically significant Weald Clay Formation at Ecclesbourne Glen near Hastings, this specimen offers a rare window into the lush vegetation of the Mesozoic era.
Acrostichopteris is part of the fern lineage and is notable for its distinctive frond structure, finely preserved pinnules, and association with other terrestrial flora in Wealden deposits. Fossilised plant remains from the Weald Clay are typically preserved in fine-grained sediments deposited in freshwater to brackish deltaic conditions — environments that supported a rich variety of plant life, including cycads, ginkgos, and conifers, alongside ferns such as this.
The visible pinna (leaflet) displays clear venation and morphology, and the fossil surface reveals the botanical texture and imprint of this ancient fern. A valuable specimen for both collectors and educators alike.
