CORYDON, Ind. (AP): Visitors to a southern Indiana cave where a treasure trove of ice age fossils was unearthed in 2010 are getting a close look at scientists' ongoing search for more ancient bones in the cave.
 
Indiana State Museum senior curator of paleobiology Ron Richards is leading a team of museum employees and others in excavations that began Thursday and end Saturday at Indiana Caverns.
 
Richards tells The Courier-Journal that allowing the public to see that work is part of the state museum's educational mission.
 
Indiana Caverns CEO Gary Roberson says the public dig is visible from the cave's walking path.
 
Four years ago, the fossilized bones of black bears, flat nosed peccaries, bison and other ice age mammals were found in the cave that's located just west of Louisville, Kentucky.
