7/29/02 Summary Winthrop fm is arkosic at T0 and becomes siliclastic in basal 300', Fossil plants are found in sandy and clayey units throughout or at least 10 levels in the unit T0 within 30m of the base. The basal several sands have larger amounts of Widdington- itites than those above It may be that it is deriving a larger sample from the conifer woodlands surrounding the faw/marnder zone where the majority of the fossil plantary record appears to be derived.
