Extract

Geometric models for the reconstuction of soft-tissue lophophore shape and arrangement have been designed for extinct fenestrate bryozoans (Starcher and McGhee, 2000) and for extinct fenestrate graptolites (Starcher and McGhee, 2003). We wish to add the material given in the following three tables as an addendum to our paper in the March 2003 issue of the Journal of Paleontology. These tables will enable other researchers to characterize quickly and quantitatively the geometry of lophophore shapes and arrangements in the colonial meshworks of extinct organisms, and will add quantitative measures of soft-tissue characteristics of extinct modular organisms to the already existing morphometric characterizations of hard-tissue skeletal aspects of colonial meshworks (Hageman, 1991; Holdener, 1994; Hageman et al., 1998).
