Three-Dimensional Bookstein Shape Coordinates and Functional Morphology of Passive Suspension Feeding in Composita (Brachiopoda, Athyridida)
DownloadSpring 2014
The effects of shell morphology on passive fluid circulation are examined in Late Mississippian through Late Pennsylvanian Composita (Brachiopoda, Athyridida) from Texas, Kentucky, and Iowa. The first three-dimensional derivation of Bookstein shape coordinates is given in association with an...

Using drilled-undrilled shell damage analysis to estimate crushing predation frequencies in modern marine gastropod assemblages
DownloadSpring 2010
Predation is a frequently studied subject, but estimating crushing predation in mollusk communities is challenging. Shells record successful attacks, but it is not always possible to identify attacks on an individual basis. Repair scar frequency is a common proxy for crushing mortality, but shell...
