Phylogenomics reconstructs an arthropod tree in which a monophyletic A rthropoda splits
into P ycnogonida+ E uchelicerata and M yriapoda+ P ancrustacea. The same chelicerate …

Abstract Waterfleas (Crustacea: Branchiopoda: Cladocera) are among the most successful
invertebrates in current freshwater ecosystems, occupying a wide range of niches …

Pancrustaceans boast impressive diversity, abundance, and ecological impact in the
biosphere throughout the Phanerozoic [1]. Molecular clock estimates suggest an early …

Abstract The Drumian Wheeler Konservat‐Lagerstätte of the House Range of Utah (Wheeler‐
HR) has yielded one of the most diverse exceptionally preserved Cambrian biotas of North …

The earliest fossils of winged insects (Pterygota) are mid-Carboniferous (latest
Mississippian, 328–324 Mya), but estimates of their age based on fossil-calibrated …

Radiodonts have long been known from Cambrian deposits preserving non-biomineralizing
organisms. In Utah, the presence of these panarthropods in the Spence and Wheeler …

Segmentation is fundamental to the arthropod body plan. Understanding the evolutionary
steps by which arthropods became segmented is being transformed by the integration of …

Identifying marine or freshwater fossils that belong to the stem groups of the major terrestrial
arthropod radiations is a longstanding challenge. Molecular dating and fossils of their …

Extant panarthropods (euarthropods, onychophorans and tardigrades) are hallmarked by
stunning morphological and taxonomic diversity, but their central nervous systems (CNS) …

Radiodonts are a morphologically and ecologically diverse clade of stem-group
euarthropods that occupied numerous ecological niches in early animal ecosystems. Many …
