Radiodont frontal appendages from the Fezouata Biota (Morocco) reveal high diversity and ecological adaptations to suspension-feeding during the Early Ordovician
Introduction The Early Ordovician Fezouata Shale Formation (485–475Ma, Morocco) is a

A new hurdiid radiodont from the Burgess Shale evinces the exploitation of Cambrian infaunal food sources
Radiodonts, a clade of Cambro-Devonian stem group euarthropods, have classically been
regarded as nektonic apex predators. However, many aspects of radiodont morphology and …
