about my recent preoccupation

[HAB911]

of new septic system............

Replaced 45 yr old septic system with new waste water treatment system. The new drain field is under pressure and only 6" deep so it waters the lawn with reclaimed quality water. Seen here is a load of sand to cover the new system. This load of sand had a few surprises in it. Days later as I was leveling some high spots, I hit what at first I thought was dinosaur bones. Come to find out, a bison vertebrae, teeth, and part of a jaw! I don't believe they are fossilized, the teeth slipped out of the jaw. Bison were native to Florida but were decimated by us by the early 1800's. pretty weird, any paleontologists around?
