> One thing I make sure of is that the lab is on the international interlab comparison wheel so that all dates are comparable regardless of which lab they are being sent to (see Allen & Bayliss 1995, in Cleal et al Stonehenge in its Landscape)  ... this is getting more and more important when we are dating the Neolithic long barrows to one century in the early Neolithic (37th century), causewayed encloses to the 36th BC and the Neolithic house horizon to a phase of possible 60-80 years, with the life of these monuments and events now being recorded at the generational scale (see Bayliss & Whittle ec 2007 Histories of the Dead Cambridge Arch Journ, and Whittle et al. in press Gathering Time - dating Early Neolithic Enclosures Oxbow)
