He adds that the only defining characteristic to the skeleton is that the man was wearing some kind of dental appliance, possibly a partial denture.
This is pretty vaguely described--probably deliberately so. But seems to me it could mean anything from a partial plate to a removable bridge to a temporary veneer. Not saying this is Gricar or that we know anything about his dental records, but I'm guessing neither York LE or BPD are going to feed us any helpful details.
The height thing would place him within range--those figures are best educated guesses based on bone lengths.
The time range would fit.
Age range seems off, but I know little of how forensic anthropologists determine age range. Anyone know how much wiggle room there is with age determined from up to decade-old bones?
