New interpretations are available from recently published appendages of Eoredlichia intermedia (Early Cambrian Chengjiang fauna), the most primitive trilobite for which appendages are known. The basis (formerly identified as the coxa) is preserved in onedoi:10.1080/03115519608619471...
the bodies of trilobites are made up of many segments, with the head region comprised of several fused segments. As with other parts of the trilobite body (the thorax and tail), these segments were associated with appendages, which ranged in function from sensing...
“We knew it could not be for mastication because the appendages are not near the head or mouth, they’re in the middle of the body,” Losso said. “This shows sexual dimorphism in trilobites, but in this case it is only expressed in the appendages. This tells us more about the r...
The fossils also revealed that specialized legs surrounding the mouth, which were used for feeding, had curved spoon-like bases. What's more, while it was previously believed that trilobites had three pairs of these appendages, the "new" fossils showed that they had four. Additionally, a fles...
The trilobite appendages, though similar to those of other lamellipedians in gross morphology, have a unique outward rotation of the anterior trunk appendages, resulting in a ‘hard wired’ lateral splay, different to that observed in other Lamellipedia. Conclusions The combination of helmetiid, ...

The digestive structures include a crop with digestive caeca, while the appendages display exopodal setae and slight heteropody (cephalic endopods larger and more spinose than thoracic and pygidial ones). The combination of these digestive structures and the heteropody has never been described ...

Moysiuk and Caron in 2019 reconsidered the agnostid appendages of agnostids from Burgess Shale, which argued for agnostids and eodiscids again as a group of trilobites (Moysiuk and Caron, 2019). Following this argumentation, consequently the eodiscid compound eye would not be that of a ...
