Look who's talking, lets revisit your description of you putting,
" the pointier the tip, the more modern, the rougher the pottery, the older"
Translated by Philly to sound more sophisticated:
^ that was taken in the middle of a day-long survey/mapping project at this site that was recently discovered. basically we're doing some basic analysis to determine when it was occupied and what we can tell about it in relation to other cultures/empires. on the first go-round last week we found pottery, which told us it wasn't pre-ceramic, as feared. the roughness of the pottery (as opposed to the fineware we're processing in the lab) suggests that it's a late formative site (which would place it around 200 CE.) however, today's analysis proved even more useful, if more tedious... on one of my many routes on an imaginary grid imposed over the contoured ridge composing the site, i came across this small lithic (stone) projectile point. comparisons to sites surrounding it suggest that it's significantly thinner than formative projectile points, indicating an advance in lithic production that's distinctly middle horizon (roughly speaking, around 600-800 CE.)
i don't get how this relates to your smouldered gooseberry stitched scarf that you accessorize with your hessian winter loafers
