The name in brackets indicates that this ammonite has been reclassified following later research. The identification of different ammonites is complex, based on very fine detail, coupled with their distribution in the rock record.
Horn Park Quarry near Beaminster is the smallest NNR in Britain, being just one acre or 0.32 hectares in size. It was once a working quarry but it is no longer and the remaining outcrop is protected by a fence. There is no collecting other than for scientific and educational purposes. A section of the fossil beds has been stripped back and protected from the weather by a removable cover. To arrange a visit, contact the Senior Reserve Manager on 07899 731404.
