Hi, John. My son is here. (He doesn't have his own CompuServe logon yet.)
The following comments are his:
The Parkville site is only a couple of years old. The swarm of collectors
hunting at the site made it appear like it was several years old! The way I
have collected at this site is to find cracks and joints in the shale. I then
pulled out big chunks of the shale, and tapped them with a hammer, until plants
begin to appear. This is a hit and miss procedure. The biggest challenge is not
finding plants, but getting the big chunks out of the cliff face.
Trilobites are most "common" in the Winterset limestone, which is a cherty,
medium bedded limestone that is found in the southeastern part of the Kansas
City area. Trilobites have been found in this layer at Gregory Blvd./I-435 east
and Blue River Rd. south of I-435.
The easiest way to locate an outcropping of Winterset is to first find the
Bethany Falls limestone, which is the thick unit below the Winterset, separated
by about 4 feet of shale. It is a massive limestone that looks a lot like
weathered concrete. It forms huge blocks (often 20 feet wide) that slide down
the slopes.
