Just how the discovery ( Figure 2.6) was received was detailed by Marie C. Stopes, the discoverer’s daughter, in an article in
Discoveries of incised bones dating back to the Pliocene or earlier persisted into the early part of the twentieth century. Opposition to them also persisted, and eventually prevailed. For example, Hugo Obermaier, professor of prehistoric archeology at the University of Madrid, wrote (1924, pp. 2–3): “traces (chiefly fluted, engraved, or grooved) have been observed on the bones of animals and shells of molluscs in Tertiary deposits at Saint-Prest, Sansan, Pouancé, and Billy, France; in the Tertiary basin of Antwerp, Holland; at Monte Aperto near Siena, Italy; in North and South America; and in several other places. . . . it is easy to explain supposed traces of human activity as the result of natural causes—such, for example, as the gnawing or biting of animals, earth pressure, or the friction of coarse sand.” But can we say for certain that this “easy” explanation is the correct one?
2.16 Bone implements From Below the Red Crag, England (Pliocene to Eocene)
In the early twentieth century, J. Reid Moir, the discoverer of many anomalously old flint implements (Section 3.3), described “a series of mineralised bone implements of a primitive type from below the base of the Red and Coralline Crags of Suffolk” (1917a, pp. 116–131). The top of the Red Crag in East Anglia is now considered to mark the boundary of the Pliocene and Pleistocene, and would thus date back about 2.0–2.5 million years (Romer 1966, p. 334; Nilsson 1983, p. 106). The older Coralline Crag is Late Pliocene and would thus be at least 2.5–3.0 million years old. The beds below the Red and Coralline Crags, the detritus beds (Table 2.1, p. 78), contain materials ranging from Pliocene to Eocene in age (Section 3.3.2). Objects found there could thus be anywhere from 2 million to 55 million years old. One group of Moir’s specimens is of triangular shape (Figure 2.7). In his report, Moir (1917a, p. 122) stated: “These have all been formed from wide, flat, thin pieces of bone, probably portions of large ribs, which have been so fractured as to now present a definite form. This triangular form has, in every case, been produced by fractures
