Abstract Cheloniellida is a rare but significant clade of artiopod euarthropods, and a major component of Vicissicaudata alongside aglaspidids. The first cheloniellid to be described was Triopus draboviensis, based on a single specimen from the Upper Ordovician Letná Formation in Bohemia. Because this specimen was believed to be missing its anterior, Triopus draboviensis has been the subject of considerable speculation regarding its affinities, with several authors combining various isolated…

An aglaspidid arthropod from the Upper Ordovician of Morocco with remarks on the affinities and limitations of Aglaspidida

A new aglaspidid arthropod is described from the Pusgillian (lower Ashgill, Upper Ordovician) Upper Tiouririne Formation near Erfoud, southeastern Morocco and it is suggested that ag laspidids are probably more closely related to trilobites than they are to chelicerates.

Upper Ordovician Thylacocephala (Euarthropoda, Eucrustacea) from Bohemia indicate early ecological differentiation

Even though the newly described taxa represent the oldest unequivocal thylacocephalans, their carapaces display several characters most similar to those of Mesozoic groups, whether these similarities reflect true close relationships and Ordovician origins for these groups or are only the result of convergent evolution is uncertain.

A Revision of the Late Ordovician Marrellomorph Arthropod Furca bohemica from Czech Republic

The enigmatic marrellomorph arthropod Furca bohemica from the Upper Ordovician Letná Formation, is redescribed. Based on existing museum specimens and new material collected from the southern slope

Burlingiid trilobites from Norway, with a discussion of their affinities and relationships

Cladistic analysis supports the genera Burlingia and Schmalenseeia as currently understood, and suggests that Schmalineeia was derived from a broadly Burlingiid–like ancestor, with S. acutangula displaying how the transition may have occurred.

The early history and phylogeny of the chelicerates

When fossil taxa are considered, the limits of the Chelicerata become less well constrained, especially true of various problematic arthropods: fossils such as aglaspidids, chasmataspids, Sanctacaris Briggs and Collins, 1988 and other Burgess Shale-type arthropODs.

An early Cambrian chelicerate from the Emu Bay Shale, South Australia

The morphology of this taxon shares many overall body features with Sanctacaris, and some with Sidneyia, particularly its gnathobasic complex, and these chelicerate affinities are corroborated by phylogenetic analyses.

The phylogeny of arachnomorph arthropods and the origin of the Chelicerata

The present study provides a detailed discussion of primary hypotheses of homology and includes a more complete range of terminal taxa than previous analyses, and provides the first convincing synapomorphies for the Arachnomorpha.

A new aglaspidid-like euarthropod from the lower Cambrian Emu Bay Shale of South Australia

A new euarthropod from the Emu Bay Shale (Cambrian Series 2, Stage 4) on Kangaroo Island, South Australia, is a rare component of this Konservat-Lagerstätte and supports close affinities to either Emeraldella or to aglaspidids, but several plesiomorphic character states are inconsistent with membership in Aglaspids sensu stricto.

The Vicissicaudata revisited – insights from a new aglaspidid arthropod with caudal appendages from the Furongian of China

A new comprehensive phylogenetic analysis provides strong support for the legitimacy of a monophyletic clade Vicissicaudata, and demonstrates the pertinence of new characters to define Aglaspidida.

The arthropodCheloniellon from the devonian hunsrück shale

The second preoral appendages and postoral gnathobases make it unexpectedly similar to eurypterids and xiphosurids, and it may be a late representative of a group of trilobitomorphs that gave rise to the Chelicerata.
