Brasilia bradfordensis was first identified and described (given a name) by William Buckland who lived in Bradford Abbas, which lies on rocks of the same age as those found at Horn Park Quarry, near Beaminster.

Horn Park Quarry is the smallest National Nature Reserve (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 hasbeen stripped back and protected from the weather by a removable cover. To arrange a visit, contact the Senior Reserve Manager on 07899 731404.
