Among the other grave-mound fossils, those of cephalopods find a place. A considerable number of belemnites lay in a “large” [i.e. British or pre-Saxon] Dorsetshire barrow opened in the eighteenth century by Colonel Drax. Douglas, who saw the specimens, figures one of them in his _Nenia Britannica_[763]. Canon Greenwell found a portion of an ammonite lying beside a skeleton in one of the Yorkshire mounds[764]. It is well to remember that a black ammonite, of which the species is not stated, is associated with the religious ceremonies of the Brahmans, being regarded by the devout as the embodiment of Vishnu[765]. Some of the larger fish teeth, occurring as fossils, also come in our list. In a tumulus described by Dr Henry Woodward, the sides of the grave were lined with the teeth of _Lepidotus_ (= _Sphaerodus_) _gigas_, a Mesozoic fish allied to the “bony pike” of North American lakes and rivers. In one case a locket-like arrangement was noticed, a kind of keyhole having been cut in the tooth[766]. I record this evidence, but not having seen the specimens referred to, cannot express an opinion on the individual example, and will merely say that the artificial nature of the hole is antecedently probable. But it is only right to add that doubt has been cast on the necessity of invoking human skill to explain certain of these orifices. Some species of boring mollusc may possibly have been the real agent. One recalls the controversy respecting the perforated sharks’ teeth of the Crag formation. To explain this feature, Mr H. A. Burrows suggested that the cavities originally represented hollows for the passage of blood-vessels, and that the perforations had been completed by subsequent friction and solution. It remains to be noted that the first collectors of fossil fish teeth lived in Palaeolithic times, since specimens, associated with flint flakes, were found at the celebrated “Palaeolithic floor” at Stoke Newington[767]. Similarly, fossil and “recent” shells, perforated for suspension, have been found in the Palaeolithic caves of France and Belgium[768]. A limestone cavern, opened by M. Dupont in the latter country in 1860, yielded a collection of fossil molluscan shells, including _Cerithium_, which must have been brought a distance of 40-50 miles. Accompanying the fossils were a piece of fluor spar and other curiosities, so that it has been suggested, with reason, as well as mirth, that here was a primitive museum[769]. British barrows have furnished specimens of the joints of encrinites (“sea-lilies”), known in folk-lore as “St Cuthbert’s beads[770].” In one case the specimen had actually been bored for stringing[771]. It is probable, indeed, that from the earliest ages men have never ceased to collect these beautiful little “beads.”
