Meeting Abstract P3.36  Jan. 6  Disparity of planispiral ammonites in the Paleozoic SWIDERSKI, D. L.; Univ. of Michigan, Ann Arbor dlswider@umich.edu Ammonites are cephalopod molluscs with coiled, chambered shells, similar to Nautilus. Many have approximately regular planispiral coiling patterns, meaning that their rate of whorl expansion (W), aperture shape (S), and relative distance of aperture from coiling […]
