Primary X-ray microtomographic study of articulated Tatelt Formation trilobites; feeding and homology interpretations are separated from imaged anatomy.
Microtomographic reconstructions of ash-entombed Tatelt Formation Protolenus and Gigoutella specimens directly preserve four post-antennal cephalic limb pairs, a labrum, mouth and digestive tissues; feeding mechanics and group-wide homologies remain comparative interpretations.
claim:event:tatelt-trilobite-3d-anatomyThe studied Protolenus (Hupeolenus) sp. specimens come from volcanic ash in the Tatelt Formation, Cambrian Series 2, Stage 4, in Morocco's Lemdad Syncline. This occurrence documents the study sample, not the genus's global first appearance or complete range.
claim:taxon:protolenusThe studied Gigoutella mauretanica specimens come from volcanic ash in the Tatelt Formation, Cambrian Series 2, Stage 4, in Morocco's Lemdad Syncline. This locality records the studied fossils, not a global distribution or complete genus range.
