Fossil Species – Palaeospondylus gunni

Palaeospondylus gunni is one of the most mysterious fossil fish-like vertebrates known from the Devonian. First described from Scotland, it is famous for its unusual anatomy and uncertain evolutionary classification, making it highly desirable among fossil collectors.

This species is characterised by its delicate skeletal outline, often preserved with surprising clarity due to the fine-grained limestone matrix. Notable fossil features commonly include:

• A slender, elongated body form

• Distinct vertebral structures

• A well-defined cranial region

• Unique morphology unlike most other Devonian fish

Because of its rarity and enigmatic traits, Palaeospondylus is considered an iconic fossil of Scottish palaeontology.

Geological Age – The Devonian “Age of Fishes”

This fossil comes from the Middle Devonian, approximately 385 million years ago, a pivotal time in Earth’s history when early vertebrates diversified rapidly.

The Devonian is often called the Age of Fishes because jawed and jawless fish flourished in both marine and freshwater environments. Fossils from this period provide vital evidence for the early evolution of vertebrate life, eventually leading toward amphibians and terrestrial animals.

Owning a Devonian fossil fish specimen is like holding a direct relic from one of the most important evolutionary chapters on the planet.

The Achanarras Limestone – World-Class Fossil Preservation

The Achanarras Limestone of Caithness is internationally famous as an exceptional fossil deposit, often regarded as one of Britain’s most important Devonian fossil sites.

Achanarras Quarry is known for producing beautifully preserved fossils due to its finely laminated sediments, which captured fragile organisms in extraordinary detail. This deposit represents a rare freshwater lake environment within the Old Red Sandstone continent.

Associated fossils from the site include:

• Early armored and jawed fish

• Arthropods

• Other rare lake-dwelling vertebrates

Collectors value Achanarras fossils for both their scientific importance and display quality.

Depositional Environment & Fossil Formation

During the Devonian, Caithness lay much nearer the equator, with warm climates supporting extensive freshwater lakes. Fine carbonate muds accumulated slowly on the lake bed, burying organisms rapidly.

Low-oxygen bottom waters limited scavenging and decay, allowing delicate skeletal forms like Palaeospondylus to fossilise with excellent preservation. Over millions of years, mineral replacement transformed the remains into lasting stone fossils within the limestone.
