I have been trying to get to grips with the book at reference 1 by Zoltan Torey, a getting to grips which has already spawned a number of digressions and a number of posts, as can be seen by searching for ‘torey’, with the most recent, reference 2, being about an Australian who is interested in ancient artefacts, particularly those which are not tools.
What I am attempting is to see what, if anything, the goings on in the prehistoric world can tell us about the state of human consciousness now. Not so much how consciousness comes to be at all, as quite a lot of animals appear to be conscious, albeit in a limited way, more what it is that makes human consciousness special. Is consciousness responsible for our success as a species, or is it merely a by-product, a bit of froth floating on the top of the brew?
In what follows I use the word ‘hominin’ to mean early humans, after the divergence from the great apes, the chimpanzees and the bonobos. With hominins having been around for a few million years, following the figure above, say five. With the serious record not starting until not much more than fifty thousand years ago, just a thin slice of the right-hand column in the timetable above. Two alternative timetables are offered at reference 2 and there is yet another below.
To this end one can look at certain extant languages as a proxy for the languages spoken in the distant past. What does that tell one about what might have been going on in early consciousness? One can also look at the stuff left behind by the hominins, with the present interest being bone tools as opposed to stone tools, with a lot of effort being put into making bone branch a respectable part of lithic studies, a sub-discipline of paleo-archaeology. This last being what comes before archaeology, which is concerned with not much more than the last ten thousand years or so. What happened when the sun came out after the ice ages.
Then, poking around in the world of the Neanderthals of western Europe, I came across retouchers, which had me puzzling. Bing turned up reference 3, from which I learn that these can be bits of bone, which can indeed be used to touch up or resharpen flint (or quartzite) blades. Digging, I find that bits of bone can also be used as tools in their own right. And while bone might not last as long in the ground as flint, it does last a long time. Which takes me to references 4 and 5, to which I was attracted by talk of a logical analytical system (LAS).
But bones do present problems. Can you be sure that the bits of bone you are finding, in this case in the floor of caves, got there by hominin rather than other animal action? Hominins were not the only animals to use caves. Then can you be sure that they had been used as tools, rather than just the result of smashing up bones for their very nutritious marrow?
[Part of Figure 8 from reference 3. ‘Retoucher from Noisetier Cave with quartzite grains still embedded and microscopic view of one of these grains…’]
One way into this is to examine the bits of bone, to describe them and then to accumulate them in a database for analysis. With, ideally, everyone using the same method of description and the same database. An example of such a bit of bone, a retoucher from reference 3, is included above. References 4 and 5, are in large part, working towards such a method.
In the beginning, the point of these tools was butchery, the cutting up of the carcases of the large herbivores needed to feed the growing brains of the hominins. A rabbit can be torn apart, while you might struggle with a red deer.
[Victorian Solid Silver Marrow Spoon Scoop Double Ended 1843]
An important part of that butchery was smashing open the long bones, the humeri and the femurs, to get at the marrow within. A hundred years ago, marrow was still something of a delicacy and people with money had special silver spoons, like that one snapped above. Not to be confused with a range of other similar looking instruments and tools, some surgical and some cosmetic. While FIL was a bit cruder about it, and hominins were cruder still. They just smashed the bones open with rocks, perhaps large pebbles, perhaps with a crude flint tool called a chopper. This was apt to result in two end pieces – with the two joints (epiphyses) – and a number of fragments of shaft (diaphysis) from in between. Some of them quite large, like that snapped above.
Eventually the hominins worked out that these fragments could be used, either as they came or perhaps lightly reworked, or retouched. They could be used to rework or retouch flint tools – or they could be used as tools in their own right: cutters, saw or scrapers – tools for working with flesh, hide or wood, all important in the hominin world.
Maybe this learning was the result of play, or at least playing around with the fragments. Then after a while, a hominin just picks a fragment out and starts using it. Perhaps, rather in the way that we might choose a cake from a baker’s display, without much conscious thought about it. Maybe just the result of the action makes it to consciousness, maybe not even that.
Picking out a fragment and then working it up to be a useful tool requires rather more. Somewhere there has to be the knowledge that this bit of bone has tool potential – although whether or not that knowledge makes it to consciousness is another matter. In which connection language would certainly be helpful, but is it necessary?
Logical analysis system
This, to my mind, turned out to be a bit underwhelming, involving a lot of terminology which did not translate very well. The table above, taken from reference 9 is the lithic version, the stone version.
Generations do exist and do explain some of the variation, but to my mind the physical description of the bit of flint explains rather more. The sort of thing, for example, to be found at Table 4 of reference 4.
But, all in all, an attempt to get a grip on the description of flakes of bone – not an easy matter as anyone who has attempted such a thing will know – but well-tried strategy for trying to understand what is going on. Devise an appropriate method of classification (aka analysis), collect statistics – and, from them, hopefully learn something about the processes involved. This cave was different from that cave in this or that (statistical) way.
My stone version, based on the thought that most of the time one is taking lots of flakes, one after the other, off the same core. Usually there is lots of visible debris and lots of not so visible dust – but it can be seen if it catches the sun. Think sunlight coming in through the windows of a dusty shed.
This simple process can be modified by what is called the Levallois technique, invented (in term of the timetable below) during the Middle Palaeolithic, whereby one takes a lot of flakes off a core in order to get a good, big flake, which might then be finished off by retouching, possibly by pressure flaking. Good for the smaller tool – but another layer of planning for our hominin to cope with. In the figure, above this is the role of flaking. Added to which is the method of flaking – one of which is pressure flaking – all of which serves to make for a rather busy diagram.
Bone flaking is much less elaborate.
And as with many complicated crafts, there is usually more than one way to achieve the desired end. I associate to a childhood anecdote about a carpenter in training who showed off to his colleagues by producing a very small piece (a small box) which he had mainly made with a very big plane (a jointer). It can be done, although there are easier ways.
Noisetier cave
The locale for some of the work described at reference 3. In the French Pyrenees at around 800m and overlooking a tributary of the Garonne. Current indications are of Neanderthal occupation between 30,000 and 50,000 years ago. More background on this cave is to be found at references 10 and 11, with the second of these being referenced at the first.
The main interest here seems to be using bone fragments as a clue to whether the hominins in question were using quartzite or flint for their tools.
All part of a mission to establish bone studies as a respectable adjunct to stone – flint and quartzite – studies in the archaeological world.
• Get to the right strata in the cave (temperate phase of OIS 3; the discovery of two deciduous teeth compatible with the range of variability of Neanderthal teeth allows us to exclude an interpretation of the site as a simple hunting camp – although what exactly the cave was used for by the Neanderthals remains a fairly open question)
• Pull out all the relevant stone and bone. Local chert, imported flint
• Sort out the bones which are the result of animal (wild Asiatic dogs, Cuon alpinus and bearded vultures, Gypaetus barbatus) rather than human action
• This leaves 18 antique bone retouchers (mostly red deer). The ‘A’ sample
• Create 73 new bone retouchers (horses and cows). The ‘B’ sample
• Test the B sample on both flint and chert and work out how the use marks differ between the two materials and other variables, for example freshness. Do some blind testing
• Use the work on the B sample to guess on what materials the A sample were used. Mostly on flint rather than chert – with this last being considered to be an inferior material.

From which I learn that the French divide up their digs rather like the cells of an Excel Worksheet, with numbers for rows and letters for columns. With detailed work taking place in complete cells. Perhaps we do it too.

Experimental bone breaking
Reference 4. Here the authors took 45 long cow bones from a butcher and broke them open with hammerstones as if to get at the marrow. This resulted in 75 fragments which could be used directly and 37 which could be used as blanks for light reworking into usable tools with quartzite pebbles. The work was then to devise and apply a method for describing these tools.
Reference 5. An earlier paper from some of the authors of reference 4. Another experiment with cow bones, but this one involving the use of the resultant tools, followed by examination for use wear – examination which included the use of microscopes. Tool use included scraping hides, scraping wood, sawing wood and processing a carcass.
The motivation being twofold: first to provide a new method for examining ancient bone fragments for use; second to make some assessment of the use value of these bone fragments, lightly retouched or otherwise.
One diversion along the way was the effect of using hydrogen peroxide to clean bone fragments before examining them with a microscope. This appears to have affected their subsequent – rather short – working lives.
Other matters
I have been impressed by the quality of the drawings of flints to be found in the literature – leading me to wonder whether the teams that go on these digs include draughtsmen as well as photographers – as I would have thought that these drawings would be well beyond the average archaeologist. In which connection, see the advertisement at reference 12.
Bone can last a long time in the ground, provided that ground is not acidic. Very little bone is found, for example, on Dartmoor. But there is plenty of bone about which is more than a million years old. I dare say also that there is plenty of bone on the way to being fossilised, to being petrified. Halfway between bone and fossil.
I doubt whether I will make it to one of the flintknapping workshops on offer, but I have started reading reference 7, an accessible and popular book, from which the Old World timetable above – Figure 3.1 – has been lifted. A book which is in part a response to the flintknapping revival – not to say craze – of the 1970s. For me, armchair flintknapping. But I have already learned that the knapping of bone, glass and chert is not that unlike the knapping of flint. Pretty much anything which is amorphous, both brittle and elastic will do.
One of the key tests here is whether you get conchoidal scars left behind when knapping. As it happens, the edge of the glass top to our sideboard got knocked a few years back and exhibits a clear if small example of same, with the scar rippling out to the left from the point of impact. It is the floor which can be seen bottom right, a paler brown wood than the sideboard. Stained pine as opposed to burr walnut veneer.
Along the way, I came across the open access ‘Journal of Lithic Studies’, to be found at reference 6, and which stretches a point to include bone as well as stone. I also found an article about riverine deposits in India, reference 8, a useful reminder that it is not all caves in the Pyrenees.
And to close, I was moved to check what ‘burr walnut’ was all about and Google turned up: ‘… the production of wood veneer burr begins with the meticulous selection of trees that exhibit burr formations. These burrs, or burls, are unique growths that occur on the trunks or branches due to stress factors like injury, virus, or fungus. These formations result in highly figured wood with intricate and unique grain patterns. Harvesting the burr wood is carried out with precision to ensure the preservation of the detailed grain, which is essential for creating high-quality veneer…’. So something that happens to a tree, rather than a sort of tree. Although that does not exclude walnut being good for burr. And maybe it should be ‘walnut burr’ (or burl) rather than ‘burr walnut’.
Conclusions
I am satisfied that I now know what a bone retoucher is, which is where I started out.
And I have found that the LAS, while interesting, is very much work in progress.
