List of the prehistoric life of Arkansas
 | This article needs attention from an expert in Palaeontology. The specific problem is: Several of the genus names (including but not necessarily limited to those tagged as {{dn}}) appear to be invalid. E.g. (1) , a brachiopod, name preoccupied by a butterfly, possibly now Neosandia or Brasilioproductus. E.g. (2) Cytherea, a mollusc, name preoccupied by a fly, now apparently split into Callista and Neocallista.. (May 2018) |
