Functional morphology, ontogeny and evolution of mantis shrimp‐like predators in the Cambrian
We redescribe the morphology of Yohoia tenuis (Chelicerata sensu lato) from the Cambrian Burgess Shale Lagerstatte. The morphology of the most anterior, promi- nent, so-called great appendage changesExpand

Morphology and function in the Cambrian Burgess Shale megacheiran arthropod Leanchoilia superlata and the application of a descriptive matrix
BackgroundLeanchoilia superlata is one of the best known arthropods from the middle Cambrian Burgess Shale of British Columbia. Here we re-describe the morphology of L. superlata and discuss itsExpand

A holomorph approach to xiphosuran evolution—a case study on the ontogeny of Euproops
Specimens of Euproops sp. (Xiphosura, Chelicerata) from the Carboniferous Piesberg quarry near Osnabrück, Germany, represent a relatively complete growth series of 10 stages. Based on this growthExpand

A Carboniferous Non-Onychophoran Lobopodian Reveals Long-Term Survival of a Cambrian Morphotype
Lobopodians, a nonmonophyletic assemblage of worm-shaped soft-bodied animals most closely related to arthropods, show two major morphotypes: long-legged and short-legged forms. The morphotype withExpand

External morphology of Lightiella monniotae (Crustacea, Cephalocarida) in the light of Cambrian 'Orsten' crustaceans.
The species-poor meiofaunal Cephalocarida have played an important role in discussions of the phylogeny and evolution of Crustacea since their discovery in 1955. One reason may be that the morphologyExpand

Evolving Pathways Key Themes in Evolutionary Developmental Biology: Basal euarthropod development: a fossil-based perspective
The morphological gap between Euarthropoda (the crown group that contains all extant arthropods) and living arthropod-like animals such as onychophorans, tardigrades and pentastomids is bridged by aExpand

A new species of Markuelia from the Middle Cambrian of Australia
We describe a new species of 'Markuelia' from the Middle Cambrian of Australia, a taxon based exclusively on embryonic specimens. The two likewise putatively embryonic specimens of the new speciesExpand

†Henningsmoenicaris scutula ,† Sandtorpia vestrogothiensis gen. et sp. nov. and heterochronic events in early crustacean evolution
A detailed account of the morphology and ontogeny of the late Middle Cambrian crustacean †Henningsmoenicaris scutula is presented. Ten successive ontogenetic stages could be recognised in theExpand

Early Crustacean Evolution and the Appearance of Epipodites and Gills
> Abstract Epipodites are structures on the outer edges of crustacean appendages serving as gills or for osmoregulation. Their evolutionary origin has been debated for a long time. Three major issuesExpand

The implications of a Silurian and other thylacocephalan crustaceans for the functional morphology and systematic affinities of the group
BackgroundThylacocephala is a group of enigmatic extinct arthropods. Here we provide a full description of the oldest unequivocal thylacocephalan, a new genus and species Thylacares brandonensis,Expand
