Abstract The last common ancestor of all living arthropods had biramous postantennal appendages, with an endopodite and exopodite branching off the limb base. Morphological evidence for homology these rami between crustaceans chelicerates has, however, been challenged by data from clonal composition knockout leg patterning genes. Cambrian arthropod fossils have cited as providing support competing hypotheses about biramy but shed little light on additional lateral outgrowths, known exites....
The artiopodans represent a diverse group of euarthropods with typically flattened dorsal exoskeleton that covers numerous pairs biramous ventral appendages, and which are ubiquitous faunal components the 518-million-year-old Chengjiang Lagerstätte in South China. Despite their abundance, several remain poorly known, such as large euarthropoda Retifacies abnormalis, Hou, Chen & Lu, 1989, is distinguished by presence mesh-like ornamentation on its exoskeleton. Although only few details were...
Abstract Artiopoda, an early arthropod group, displays post-antennal appendages resembling trilobite limbs, but relationships with other ealy arthropods remain enigmatic. Limited studies and morphological details hinder the understanding of internal within Artiopoda. Recently, exceptionally well preserved fossils from Chengjiang Biota were studied using X-ray computed tomography, revealing detailed morphologies. In this study, Cindarella eucalla , a xandarellid Biota, was re-investigated...
