A misconception shared by many non-palaeontologists is that fossils are rare. For example, when governments pass legislation to protect their fossil heritage, they are stopping the export of complete and well-preserved specimens, such as those of Mesozoic dinosaurs, hominids and Ice Age mammoths. There can be little argument that protecting their prehistoric heritage is responsible. Yet, these same politicians will support, for example, the export of cement. This may seem unrelated, but, of course, limestone is rich in fossils, most particularly invertebrates (Bathurst, 1971), and is an essential component of cement. These fossils are not dinosaurs or mammoths, admittedly, but they are fossils nonetheless. Legislation needs careful wording to ensure that exporting cement is not an illegal activity.
Fig. 1. Imported rocks used in raised flowerbeds and paving at Amsterdam Zuid (=south) railway station, the Netherlands. (A) General view. The grey stone is Carboniferous limestone; the pink stone is gneiss. The Wagamama restaurant is to the left of the photographer. (B) Detail of the upper surface of limestone on a raised flower bed. The fossils are dominantly fragments of crinoid and a colonial tabulate coral (Michelinia? sp.) is seen towards the bottom of the page and a section through a productid brachiopod(?) is right of the coin. The coin is €2, about 25mm in diameter.
