Description

Fossil Chalk Fish Bones – Osteichthyes

Geological Period: Cretaceous (Late)

Age: Approximately 100 to 66 million years ago

Formation: Grey Chalk Subgroup

Locality: Clyde, Sussex, United Kingdom

This listing presents a fascinating fragment of fossilised fish bones from a bony fish (class Osteichthyes), embedded in the iconic Grey Chalk of southern England. Recovered from Clyde, Sussex, this specimen dates to the Late Cretaceous, a time when much of the UK was submerged beneath a shallow, warm sea.

The Grey Chalk Subgroup is part of the broader Chalk Group, deposited during the Late Cretaceous and composed primarily of coccolith-rich calcareous sediments. These marine chalks frequently yield well-preserved micro- and macrofossils, including the remains of fish, marine reptiles, ammonites, and echinoderms.

Fish remains from this unit, including bones, scales, and teeth, are relatively scarce and often highly fragmented, making well-preserved examples like this a prized find. The bones may include partial vertebrae, fin rays, or cranial fragments — each offering insights into the structure and diversity of ancient marine vertebrates.
