DESCRIPTION:A sediment sample collected from the ceiling of a small cave in
  Sullivan County\, Tennessee has yielded a unique assemblage of vertebrate
  remains. Paleontological interest in collection was driven by the obvious
  presence of hellbender (Cryptobranchus alleghaniensis) remains on the sur
 face of the sample. Screening and processing revealed an unusual fauna lac
 king in typical terrestrial trogloxenes (ex. bats\, packrats). Instead\, t
 his sample is dominated by Cottus sp. (sculpin) remains\, with an incredib
 le number of individuals represented in the small sediment sample.\n\nNume
 rous disarticulated but evidently complete skeletons of these fish\, as we
 ll as at least two hellbenders\, suggest minimal transportation of these a
 nimals prior to deposition and indicate a local source for these remains. 
 Other animals are represented only by fragmentary or isolated remains whic
 h suggests they were already fragmentary/isolated prior to transport or th
 ey were transported a long distance. Sedimentological and contextual evide
 nce supports deposition during a backflooding event.\n\nThis collection pr
 ovides additional evidence for the troglophilic nature of Cottus sp. sculp
 in and potential evidence for utilization of caves by hellbenders. Future 
 work will include radiometric dating of remains and additional collection 
 of sediment samples.
