Evaluating the effects of morphology and orientation on feeding in atrypide brachiopods using 3-D printed models

The brachiopod order Atrypida was one of the most diverse and abundant clades of marine organisms across North America during the Silurian and Devonian. Atrypide brachiopods were active sessile suspension feeders that used their lophophores to capture food particles from the water. Within the subfamily Variatrypinae, there are two end-member morphotypes associated with either high or low energy environments. It has further been suggested shape...
