Abstract A new synziphosurine (Chelicerata:Xiphosura) is described from the Late Llandovery (Silurian) Konservat-Lagerstätte of Waukesha, Wisconsin, USA. Venustulus waukeshaensis n.gen. and sp. is characterized by a semicircular carapace with a slightly procurved posterior margin lacking genal spines and an opisthosoma composed of 10 freely articulating segments, divided into a preabdomen of seven segments with blunt pleurae and a postabdomen of three segments lacking pleurae. The tail spine is… 

Synziphosurines (Xiphosura: Chelicerata) from the Silurian of Iowa

TLDR
A comparison of the musculature of C. grovensis with that of living Limulus polyphemus and the Jurassic Mesolimulus walchi from Nusplingen, Germany shows that it is much simpler, consistent with the status of synziphosurines as stem xiphOSurids.

A CARBONIFEROUS SYNZIPHOSURINE (XIPHOSURA) FROM THE BEAR GULCH LIMESTONE, MONTANA, USA

Abstract:  A new synziphosurine, Anderella parva gen. et sp. nov., extends the known range of this group from the Silurian to the Carboniferous and is the youngest known so far from the fossil

Revised systematics of Palaeozoic ‘horseshoe crabs’ and the myth of monophyletic Xiphosura

TLDR
A number of other characters, including the form of the chelicerae and appendage VII, indicate that xiphosurans may be paraphyletic with respect to a clade consisting of chasmataspidids, eurypterids, and arachnids.

THE OLDEST HORSESHOE CRAB: A NEW XIPHOSURID FROM LATE ORDOVICIAN KONSERVAT‐LAGERSTÄTTEN DEPOSITS, MANITOBA, CANADA

Abstract:  A remarkable new fossil horseshoe crab, Lunataspis aurora gen. et sp. nov., from recently discovered Upper Ordovician (c. 445 Ma) shallow marine Konservat‐Lagerstätten deposits in Manitoba

A glyptocystitid cystoid affinity for the putative stem group chelicerate (Arthropoda: Aglaspidida or Xiphosura) Lemoneites from the Ordovician of Texas, USA

TLDR
Cladistic analyses placed Lemoneites as “sister group to all other [eu]chelicerates . . . probably a common ancestor of Chelicerata”, as the possible ancestor of Xiphosura (Anderson & Selden 1997), or within a ‘chelicerate-allied’ clade of arachnomorph arthropods (Cotton & Braddy 2004).

The implications of a Silurian and other thylacocephalan crustaceans for the functional morphology and systematic affinities of the group

TLDR
While the new features reported here are consistent with a eucrustacean affinity, most previous hypotheses for the position of Thylacocephala within Eucrustacea (as Stomatopoda, Thecostraca or Decapoda) are shown to be unlikely.

Ceratiocaris from the Silurian Waukesha Biota, Wisconsin

TLDR
The presence of characteristic near-shore species and C. pusilla, only known from turbidite facies, interpreted to possibly represent a marine trough, suggests that the Waukesha phyllocarid assemblages might represent a transported assemblage, rather than a biota, or that C. popsilla from the Jones Creek Formation was transported basinward in sediment gravity flows.

The early history and phylogeny of the chelicerates

TLDR
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.

A Larval Sea Spider (Arthropoda: Pycnogonida) from the Upper Cambrian ‘orsten’ of Sweden, and the Phylogenetic Position of Pycnogonids

TLDR
The pre‐cheliceral limbs in this fossil support traditional morphological studies in which the chelicera represent the second head appendage corresponding to the crustacean ‘second antennae’, and contradict recent data based on homeobox genes implying that theChelicerae are the first (a1) head appendages homologous with crustaceans first antennae.

TLDR
The great interest, attached to this new Crustacean is, that it appears to offer just the link the authors needed to connect the Xiphosura with the Eurypterida.
