ABSTRACT A new chasmataspid (Chelicerata: Chasmataspidida) is described from the Early Silurian (Late Llandovery–Early Wenlock) of Lesmahagow, Scotland, as Loganamaraspis dunlopi gen. et sp. nov. It is distinguished from related forms by the low tapering ratio of the postabdomen, pediform sixth prosomal appendage and a heart-shaped metastoma. Additionally, a genital operculum with a genital appendage is preserved. The recognisable morphology of L. dunlopi gen. et sp. nov. bridges some of the… 
A redescription of Chasmataspis laurencii Caster & Brooks, 1956 (Chelicerata: Chasmataspidida) from the Middle Ordovician of Tennessee, USA, with remarks on chasmataspid phylogeny
TLDR
The type material of Chasmataspis laurencii from the Middle Ordovician of Sevier County, Tennessee, USA, is redescribed, and comparisons are drawn with recently discovered Devonian chasMataspidids from Scotland, Germany and Russia.
Redescription of Drepanopterus abonensis (Chelicerata: Eurypterida: Stylonurina) from the late Devonian of Portishead, UK
TLDR
Hibbertopteroids are the most long-ranging stylonurids, surviving the decline and extinction of the other eurypterid families in the Late Devonian, their survival probably because of their sweep-feeding mode of life, which was not in direct competition with their euryopterine relatives and other predators.
Sea scorpions (Chelicerata, Eurypterida) from the Lower Devonian (Siegenian) of the Lahrbach Valley/Westerwald area (SW Germany, Rhineland-Palatinate)
A Lower Devonian (Siegenian) eurypterid association from a particular mudstone layer in the Lahrbach Valley near Bürdenbach/Westerwald is described. It is dominated by a species of the
A common arthropod from the Late Ordovician Big Hill Lagerstätte (Michigan) reveals an unexpected ecological diversity within Chasmataspidida
TLDR
The large body size and well-developed appendage armature of Hop litaspis reveals that chasmataspidids occupied a greater breadth of ecological roles than previously thought, with the abundance of available specimens indicating that Hoplitaspis was an important component of the local community.
A new Ordovician arthropod from the Winneshiek Lagerstätte of Iowa (USA) reveals the ground plan of eurypterids and chasmataspidids
TLDR
Winneshiekia provides further support for the polyphyly of synziphosurines, traditionally considered the stem lineage to xiphOSurid horseshoe crabs, and by extension the paraphyly of Xiphosura, and provides evidence of character polarity in chasmataspidids and eurypterids.
REINTERPRETATION OF THE SILURIAN SCORPION PROSCORPIUS OSBORNI (WHITFIELD): INTEGRATING DATA FROM PALAEOZOIC AND RECENT SCORPIONS
TLDR
The morphology of the Late Silurian scorpion Proscorpius osborni from the Phelps Member of the Fiddlers Green Formation of New York, the ‘Bertie Waterlime’ of earlier stratigraphic schemes, is revised based on studies of new and existing material.
Eurypterida (Chelicerata) from the Welsh Borderlands, England
TLDR
Eurypterids from the Welsh Borderlands of England are redescribed from most available material and the phylogenetic position of the new genus is inferred to lie between the Hughmilleria and the Slimonia/Salteropterus clades.
A diverse chasmataspidid (Arthropoda: Chelicerata) fauna from the Early Devonian (Lochkovian) of Siberia
TLDR
‘Eurypterus’ stoermeri and ‘Tylopterella’ menneri are both redescribed as chasmataspidids, having previously been assigned to Eurypterida, and the presence of ophthalmic ridges is confirmed within Diploaspididae, and new structural characteristics of their bucklers.
CHELICERATE ARTHROPODS, INCLUDING THE OLDEST PHALANGIOTARBID ARACHNID, FROM THE EARLY DEVONIAN (SIEGENIAN) OF THE RHENISH MASSIF, GERMANY
TLDR
The chasmataspidid closely resembles Diploaspis casteri from the Emsian assemblage of Alken an der Mosel, but is readily discernible as a new species, D. muelleri, by a strong tuberculation of its dorsal integument.

Problems of functional morphology and classification in stylonuroid eurypterids (Chelicerata, Merostomata), with observations on the Scottish Silurian Stylonuroidea *
TLDR
In response to certain anatomical and physiological constraints which otherwise would have rendered the animals unstable in the walking position, the post-abdomen and telson have been specialised as hydrodynamic structures for monitoring water movements and vectoring the animal for maximum walking efficiency.

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.
Arthropods from the Lower Devonian Severnaya Zemlya Formation of October Revolution Island (Russia)
TLDR
This new chasmataspid material reveals two important morphological characters for the group: a genital appendage and metastoma that were previously considererd autapomorphic for eurypterids; their presence in chasMataspids strongly suggests that Chasmatspida and Eurypterida are sister groups.
The functional morphology of mating in the Silurian eurypterid, Baltoeurypterus tetragonophthalmus (Fischer, 1839)
TLDR
The functional morphology of the genital appendages, horn organs and modified prosomal limb III of the Silurian eurypterid, Baltoeurypterus tetragonophthalmus (Chelicerata: Eurypterida) is investigated and a model of mating is suggested, suggesting that sperm transfer using spermatophores and storage of sperm in sperMathecae, allowed the timing of egg production in euryopterids to be controlled.
Paleolimulus, an early limuline (Xiphosurida), from Pennsylvanian‐Permian Lagerst tten of Kansas and taphonomic comparison with modern Limulus
TLDR
Based on actualistic taphonomic experiments on Limulus polyphemus, ancient horseshoe crabs and other arthropods having non-mineralized exoskeletons are inferred to have become pliable soon after death or moulting, and to have disarticulated slowly prior to burial.

Morphology, taxonomy, and classification of the order Eurypterida Burmeister, 1843
TLDR
For the first time, a uniform, standardized taxonomy is proposed for classification and identification of most genera of eurypterids based on the observation that most higher taxonomic levels for arthropods arebased on the structure and arrangement of the appendages.
