Fossil Hunting at Smallmouth Sands, Dorset | UK Fossils Road Tour by UK Fossils
Join the UK Fossils Road Tour as we explore Smallmouth Sands, Dorset, a remarkable fossil collecting location within Portland Harbour near Weymouth. This often overlooked site exposes the Lower Jurassic Kimmeridge Clay and is recognised as one of the most diverse Kimmeridge Clay reptile assemblages anywhere in the world. Fossils here are usually tiny, but they can be abundant, with careful collectors finding small vertebrate remains, fish material and shells scattered across the foreshore, especially after favourable tides and storms.
Smallmouth Sands is very different from many other Jurassic Coast fossil sites. Success here comes from slow, careful searching rather than looking for large, obvious specimens. The sheltered setting of Portland Harbour means erosion is relatively low, so fossils are released gradually and often occur as small fragments within shingle and clay-rich patches. The site is especially important for pterosaur remains, with a wide range of forms recorded, alongside marine reptiles, fish, sharks, crocodiles, turtles and occasional dinosaur material.
In this video, we cover:
• Fossil hunting at Smallmouth Sands near Weymouth
• Why this Kimmeridge Clay site is so important for Jurassic reptiles
• Searching for tiny fossil fragments in shingle and clay-rich areas
• Pterosaur bones, teeth and other rare vertebrate remains
• Marine reptiles including ichthyosaurs, plesiosaurs, pliosaurs and crocodiles
• Fish, shark, shell and occasional ammonite finds
• Why patience and careful observation are essential at this location
• Responsible collecting at a GCR conservation site and SSSI
The most productive collecting is usually found by scanning the foreshore slowly, especially where finer material has accumulated near clay patches and washed areas. Many fossils may only be a few millimetres to a couple of centimetres in size, so this is a location where training your eye is just as important as covering distance.
Smallmouth Sands is also scientifically important, and any unusual or significant finds should be recorded. The site is a GCR conservation site and SSSI, so collecting must be carried out responsibly and sensitively at all times.
⚠️ WARNING: Fossil collecting can be dangerous. Always check tide times, weather conditions, cliff stability, local restrictions and access information before visiting any location. Never hammer cliffs, keep away from unstable slopes, and always collect responsibly.
