The Mississippian Fort Payne Formation of Kentucky, Tennessee, and Alabama
is well known for its abundant crinoids and a diverse array of
autochthonous and allochthonous carbonate and siliciclastic facies. Using
Principal Coordinate Analysis and Non-Metric Multidimensional Scaling, it
is demonstrated that distinct, contemporaneous, and geographically
adjacent autochthonous facies in south-central Kentucky supported distinct
crinoid assemblages. The two carbonate buildup facies had different
assemblages dominated by camerate crinoids, carbonate channel-fill
deposits were dominated by advanced cladid crinoids and the camerate
Elegantocrinus hemisphaericus, and green shale facies supported a fauna
dominated by disparids and primitive cladid crinoids. Allochthonous facies
contain neither distinctive nor exotic taxa. Thus, these transported
assemblage are considered a mixture of elements from the recognized,
autochthonous facies. Faunal assemblages from Dale Hollow Reservoir are
allochthonous; and faunas in north- central Alabama and south-central
Tennessee are different from others, which may reflect slight
biogeographic distinctions.
