.../Ocklawaha Rivers. We assessed taphonomy of two gastropod species: the native Elimia floridensis ( n = 2504) and introduced Melanoides tuberculata ( n = 168). We quantified seven taphonomic attributes (aperture condition, color, fragmentation, abrasion, juvenile spire condition, dissolution, and exterior...
