Thanks for the update! Had Louise left for good? Wow Belfast only sent me the final results. Not sure what standards they are using, but i shall ask. Somehow strange...The are all lower in N by 3 per mill. I remember there was one tooth instead of bone. That could be interesting as it will show a childhood diet. It would be nice to get those results before Berlin on the 19th of March, i would be grateful. Glad you will be coming to the States! Do you know what time you arrive? I will be arriving on the 12th and will be staying 100 miles north at the winyard region of Northern California in Mendosino bay. Maybe be can go hiking together in redwoods for a day if you come earlier, then Steve will take us to the conference? xxxG On Thu, Feb 5, 2015 at 7:48 PM, BIAX <[log in to unmask]> wrote: > Hello Rosie, > > These are rhizomes (uncharred) and nodules (possible charred) of Equisetum > At least that's what I think > Check the anatomy of the rhizome cells.
