With the sea on your left, walk along past the beach huts and chalets, and you will arrive in just a few minutes. At low tide, you can walk miles along the coast if you have the stamina, but it's hard work on the rockier stretches, and you cannot safely climb the cliffs if you get cut off. Ammonites are one of the most famous fossils at Lyme. You may find a specimen which shows the ribs on the outside of the shell, but these soon get worn away by the action of the waves. Some fossils are full of sparkling white calcite crystals, and others are made of iron pyrites or fool's gold - Black Ven is a good place to find small pyritised ammonites if you are patient.
Fossil wood is quite common.
This piece is the biggest I've seen, about 120cms long, and is embedded in a hard limestone nodule . Some of the wood is brownish and fibrous-looking, like this, and other is much more like hard coal. Nodules can be a good source of whole fossils - they are rounded pale grey stones, often with faint horizontal striations in them. Shells other than ammonites are also common - mostly bivalves like this big clam, which has a shell about 15cms across. Mostly they occur in a broken jumble of debris like this, but at Black Ven you can sometimes find more complete examples.
