ABsTRACT-Collectively, studies of the structure of Neogene diversity change in tropical American mollusks have lacked 1) specieslevel analyses within well-established Glades; 2) consideration of abundance and sample size on diversity estimates and comparisons; and 3) geographic comparisons within
temporal intervals. This study takes all three factors into consideration and compares Miocene to Recent species richness patterns in tropical American marginellid gastropod species within the clade Prunum + Volvarina. Rarefaction analyses of more than 16,000 specimens from more than 500 samples are used to standardize comparisons of species richness through time and space. Species richness in ...
