possible Miocene spicule

Possible spicule, from lacustrine or marginal marine strata, Miocene of Mississippi, from what is sometimes called the Hattiesburg Formation (http://mrdata.usgs.gov/geology/state/sgmc-unit.php?unit=MSMIph;0). Any expert or knowledgeable suggestions as to what it is?

The verdict is in: almost certainly a plant trichome. This is a hair or modified hair on a leaf or stem.
