NEW PERMIAN CRINOIDS FROM THE BATTLESHIP WASH PATCH REEF IN SOUTHERN NEVADA
|
ABSTRACT -
The small crinoidal patch reef in the Bird Spring Formation near the mouth of Battleship Wash, Clark County, Nevada, has yielded the largest Early Permian crinoid fauna known in North America. Earlier studies of the fauna were based on 535 specimens. Additional collecting has yielded another 239 specimens. These new specimens provide new information about some of the earlier described species and include three new genera and seven new species, bringing the total recognized i...
