Trotternish is underlain by
basalt, which provides relatively rich soils and a variety of unusual rock features. The Kilt Rock is named after the
tartan-like patterns in the cliffs. The
Quiraing is a spectacular series of
rock pinnacles on the eastern side of the main spine of the peninsula and further south is the rock pillar of the
Old Man of Storr. Trotternish is also known for its
Middle Jurassic aged rocks (c. 174–164 million years old), which yield a variety of fossils including dinosaurs. These are strictly protected by law by the Skye Nature Conservation Order 2019. Dinosaurs known from Trotternish include
theropods,
sauropods,
thyreophorans, and possible
ornithopods. Many of Skye's dinosaur body fossils and footprints can be viewed at the Staffin Museum in
Ellishadder, Staffin. The most accessible shoreline localities to view dinosaur footprints include
Duntulm, Brother's Point, and An Corran.
Conservation designations The north-eastern part of the peninsula around Quiraing is designated as the
Trotternish National Scenic Area, one of the forty such areas in Scotland, which are defined so as to identify areas of exceptional scenery and to ensure its protection from inappropriate development. The designated area covers 7,919
ha in total, of which 6,128 ha is on land, with a further 1789 ha being marine (i.e. below
low tide level, and covering the seas to the east of the peninsula). The entire length of the Trotternish escarpment is protected as a
Special Area of Conservation under the
Natura 2000 programme, and classified as a
Category IV protected area by the
International Union for Conservation of Nature. ==History==
