My home is surrounded by trees and wetland. The latter includes a protected species, so the wetland is protected as well. While spraying herbicide on invasive multiflora roses and oriental bittersweet (I abandon organic methods when it comes to aggressive invasives), I noticed this skeletal remains had been washed out of the earth. I carefully cleaned it up, let it dry, then tried to learn what animal it may have been. I say turtle. My wife says skull, maybe a small deer. Neither of us can find photos that match, either in our books or on the Web. Any guesses, folks? Top view- Bottom view- Side view- Closeup side- Closeup underside- Closeup ribs- Closeup spinal cord, and what look like vent holes- or is this a Klingon starship? Closeup side & maybe ribs- Macro of "neck" where the vertebra is broken- 1st 3 are with the PL20. Next 5 are with Vivitar 28mm "close focus". Last one is the weird Jupiter-12 28mm with a Nikon "S" adapter and a macro ring.
