Exceptional multifunctionality in the feeding apparatus of a mid-Cambrian radiodont

Joseph Moysiuk & Jean-Bernard Caron
Radiodonts (stem Euarthropoda) were ecologically diverse, but species generally displayed limited functional specialization of appendages along the body axis compared to crown group euarthropods. This is puzzling because such functional specialization is considered to have been an important driver of euarthropod ecological diversification. One way to circumvent this constraint could have been the functional specialization of different parts of the frontal appendages, known to have been ecologically important in radiodonts. This hypothesis has yet to...
