Yaverland Fossil Sites
Early Cretaceous (125-120 million years ago)
Yaverland is a fossil locality on the east coast of the Isle of Wight, situated just north of Sandown at the foot of Culver Down. Though less famous than the south-west coast sites at Compton Bay and Brighstone, Yaverland has produced significant palaeontological material and offers a different geological exposure that complements the Wessex Formation localities. The site is particularly noted for dinosaur footprints, plant fossils, and material from the slightly younger Vectis Formation.
The geology at Yaverland differs from the south-west coast in important ways. While the Wessex Formation is present, the overlying Vectis Formation is also well exposed here. The Vectis Formation represents a transitional environment between the freshwater floodplains of the Wessex Formation and the marine conditions that would eventually dominate as sea levels rose during the later Cretaceous. The rocks include dark mudstones and shelly limestones that preserve a different suite of fossils from the Wessex Formation below.
Dinosaur footprints are the most celebrated feature at Yaverland. The foreshore exposes bedding planes that preserve extensive trackways, including prints attributed to large iguanodontian dinosaurs and smaller theropods. Some of these track surfaces are among the best-preserved dinosaur footprint sites in Britain, with individual prints showing clear toe impressions, skin texture, and the displacement ridges created as the animal's foot pushed through soft sediment. The tracks are exposed at low tide and can be difficult to see in dry conditions, but they become conspicuous when the rock surface is wet.
Plant fossils from Yaverland include well-preserved conifer foliage, fern fronds, and material from bennettitaleans, an extinct group of seed plants that superficially resembled cycads. The plant assemblage provides evidence for the local vegetation and can be compared with the flora of the Wessex Formation to track changes in plant communities over time. Some of the Yaverland plant material is preserved in fine-grained mudstone that retains remarkable detail.
Invertebrate fossils are more common at Yaverland than at the south-west coast sites, reflecting the transitional marine influence of the Vectis Formation. Shells of freshwater bivalves, gastropods, and ostracods are found in some horizons, along with occasional marine or brackish-water species that indicate periodic flooding by the sea. These invertebrate assemblages are important for understanding the environmental conditions under which the sediments were deposited.
Access to the Yaverland foreshore is from the car park near Yaverland sailing club, with a short walk across the beach to the fossil-bearing platforms. As with all Isle of Wight coastal sites, tide awareness is essential, and collectors should avoid the cliff base. The site is within walking distance of Sandown, making it easily combined with a visit to the town's seafront and other attractions.
