Paleocommunities of the Fort Thompson Formation (Pleistocene) of Florida

Morphometric Analysis of Mercenaria campechiensis

Andrew Bush performed a Procrustes analysis on morphological landmarks of M. campechiensis collected within the grid formed by the paleoecologic bulk samples. According to a cannonical variates analysis (graph below), the clams from the lower zone were significantly morphologically distinct from those from the upper zone.
