A relatively uncommon arthropod of the Waukesha lagerstätte, Parioscorpio venator, is redescribed as an arthropod bearing a combination of characters that defy ready classification. Diagnostic features include sub‐chelate ‘great appendages’, a lack of antennae, multiramous anterior trunk appendages, filamentous fan‐like rear trunk appendages, and apparently thin and poorly preserved pleural fields. Phylogenetic analysis resolves this organism as basal to crown‐group Mandibulata and Chelicerata… 

Redescription of the cheloniellid euarthropod Triopus draboviensis from the Upper Ordovician of Bohemia, with comments on the affinities of Parioscorpio venator

It is shown that the holotype of Triopus draboviensis preserves the complete cephalic shield, while the trunk reveals a likely articulating device, which may represent an apomorphy for Cheloniellida, making Drabovaspis complexa the third cheloniellid genus known from the Letná Formation, after Triopus and Duslia.

Spider Origins: a Palaeontological Perspective

Spiders (Araneae) can be defined as spiders which have lost the telson, something which appears to have occurred multiple times among arachnids.

Conulariids from the Silurian (late Telychian) Waukesha Lagerstätte, Wisconsin

ABSTRACT The Silurian (late Telychian) Brandon Bridge Formation, Wisconsin, USA, is renowned for hosting the Waukesha Konservat-Lagerstätte, in which several rare, enigmatic constituents have

A new genus and species of ?parthenogenic anostracan (Pancrustacea, Branchiopoda, ?Thamnocephalidae) from the Lower Cretaceous Koonwarra Fossil Bed in Australia

Abstract The fossil record of fairy shrimp, or anostracan crustaceans, is poor with only six species formally described to date. The group stratigraphically ranges from the Devonian to recent. The

The first fossil scorpion from Australia

Abstract The fossil record of scorpions in Australia is effectively non-existent. This lack of data is striking as there is evidence for other euchelicerates including eurypterids, spiders, and

Fossils of Blackberry Hill, Wisconsin, USA: the first animals on land, 500 million years ago

Recent discoveries of trackways and trails on ancient tidal flats at Blackberry Hill, Wisconsin, USA, have transformed our understanding of the initial invasion of land, 500 Ma. Huge slug‐like


Abstract: Here we describe an epibiont association between conulariids and holdfast producers, with attachment scars resembling those of the tubular epibiont, Sphenothallus, from the Silurian (late



A large new leanchoiliid from the Burgess Shale and the influence of inapplicable states on stem arthropod phylogeny

A new leanchoiliid is described, Yawunik kootenayi gen. nov, based on 42 specimens from the newly discovered Marble Canyon locality of the Burgess Shale, which stresses the historical importance of polarization over data content in scenarios of early arthropod evolution and a pressing need to investigate the impacts of coding inapplicables, especially given the inflating effect of implied weights.

Soft Anatomy of the Early Cambrian Arthropod Isoxys curvirostratus from the Chengjiang Biota of South China with a Discussion on the Origination of Great Appendages

Morphological comparisons demonstrate that species of Isoxys were diverse in feeding habits and occupied a very broad morphospace, i.e., carapace bivalved or a single shield, the pre-oral limbs antenniform or modified into great appendages, the succeeding endopods slim or stout.

A Silurian ‘marrellomorph’ arthropod

Morphological comparisons and cladistic analyses of X. chledophilia indicate affinity with Vachonisia rogeri from the Lower Devonian Hunsrück Slate, within the marrellomorphs, but assignment to Marrellomorpha is provisional pending revision of other members of this clade.

A new arthropod from the Silurian Konservat–Lagerstätte of Herefordshire, UK

A small, non–biomineralized, macrophagous arthropod with chelicerate affinities, Offacolus kingi gen. et sp. nov., from the Silurian (Wenlock Series) of Herefordshire, UK, is described. The dorsal

Morphology and function in the Cambrian Burgess Shale megacheiran arthropod Leanchoilia superlata and the application of a descriptive matrix

Different aspects of the morphology, for example, the morphology of the great appendage and the presence of a basipod with strong median armature on the biramous appendages indicate that L. superlata was an active and agile necto-benthic predator (not a scavenger or deposit feeder as previously interpreted).

The Arthropod Alalcomenaeus cambricus Simonetta, from the Middle Cambrian Burgess Shale of British Columbia

Alalcomenaeus was probably a predator, moving mainly by swimming, and is now known to be one of the more abundant, widely distributed and longest ranging of Burgess Shale arthropod genera.

Cephalic and Limb Anatomy of a New Isoxyid from the Burgess Shale and the Role of “Stem Bivalved Arthropods” in the Disparity of the Frontalmost Appendage

The diversity of frontalmost appendages in “stem bivalved” arthropods, distinct in its absence of clear clustering, is found to link the morphologies of “short great appendages,” chelicerae and antennules, and fits the hypothesis of an increase in disparity of the deutocerebral appendage prior to its diversification in euarthropods.

Functional morphology, ontogeny and evolution of mantis shrimp‐like predators in the Cambrian

The arrangement of the elbow joint supports the view that the great appendage evolved into the chelicera of Chelicerata sensu stricto, as similar joints are found in various ingroup taxa such as Xiphosura, Opiliones or Palpigradi.

Chelicerate neural ground pattern in a Cambrian great appendage arthropod

Alalcomenaeus and Fuxianhuia protensa demonstrate that the two main configurations of the brain observed in modern arthropods, those of Chelicerata and Mandibulata, respectively, had evolved by the early Cambrian.

Silurian horseshoe crab illuminates the evolution of arthropod limbs

Both branches of the prosomal limbs of this new fossil are robust and segmented in contrast to their morphology in Cambrian arthropods, revealing that a true biramous limb was once present in chelicerates as well as in the mandibulates.
