One of the challenges in prehistoric, and most especially Mesolithic, lithic studies is that there is no coherent standard on how to approach and conduct an analysis. References exist but are scattered through decades of literature, some obscure. Case studies are in every archaeological report, and critiques thereof (referencing Alan Saville on Stephen Mithen’s West Hebrides project as a good example*) but often at summation and “interpreted results” levels, not the methodological practicalities. Just how does one deal with assemblages of 30, 300, 3,000, 300,000 or more flints, whether derived from coincidental or rescue “watching brief” excavation, focused/targeted excavation, field-walking or from surface erosion areas?
What is best practice, what are the priorities and minimum desiderata? How does one construct a “future-proof” database that avoids or mitigates inevitable subjectivity? Whose typology is right—there are three or four just for microliths, and can anyone properly define a “rod” vs a straight-backed-bladelet (SBB) that might have retouch on the leading edge—and why does it matter typologically or chronologically**? And while best practice is to bag every flint to prevent chaffing, the late Roger Jacobi*** himself was an exponent of throwing it all out on the table!

New to British flint typologies?
Just a quick recommendation—if you need an overview of British prehistoric flint technology and typologies. Chris Butler’s Prehistoric Flintwork (Tempus 2005, affordable and widely available) is an excellent one-stop reference. The Mesolithic section is especially useful with a summary of microlith and major tool form typolologies. The rendition of Roger Jacobi’s microlith typology is covered on pages 94-6 and there’s a good summary of Early Mesolithic and Late Mesolithic chronological patterns—including the “Star Carr” and “Deepcar” types. To drill down any further you really have to start wandering through large excavation volumes where unfortunately few precise typological definitions are available or illustrated comprehensively. One rare exception is C.R. Wickham-Jones’ volume on excavations at Rhum (Society of Antiquaries of Scotland, Monograph Series No 7 1990, Edinburgh). The South Hebrides Mesolithic Project typologies (Mithen et al.) are probably a bit of a minefield although there are useful discussions. For clear and precise descriptive terminology for lithics, the Inizen volume (see next section) is invaluable, as is Andrefsky’s Lithics volume if used with caution.
One man’s rod is another man’s backed?
I’m currently using an amalgam of the following typological protocols:
- Base template courtesy of Peter Rowe, Tees Archaeology NE Yorkshire Mesolithic Project (spreadsheet) adapted to include blank (blade/flake) data and secondary modification.
- Central Pennine typology courtesy of Dr Paul R Preston (doctoral thesis) for standardised terminology, morphological definition, additional metrical data points (e.g. retouch location, platform preparation, etc.) and raw material typology | publication forthcoming.
- Checked against Dr M Reyniers protocols for his Early Mesolithic doctoral thesis published as Reynier, M. J., 2005, Early Mesolithic Britain: origins, development and directions. BAR 393. Oxford: Archeopress.
