Rheotaxis in the Ediacaran epibenthic organism Parvancorina from South Australia
Diverse interpretations of Ediacaran organisms arise not only from their enigmatic body plans, but also from confusion surrounding the sedimentary environments they inhabited and the processesExpand

Abnormal xiphosurids, with possible application to Cambrian trilobites
Xiphosurida comprise an archetypal arthropod group of considerable interest to both biological and palaeontological researchers. This appeal is generated by a combination of unique anatomicalExpand

Revision of “Bellinurus” carteri (Chelicerata: Xiphosura) from the Late Devonian of Pennsylvania, USA
Abstract Horseshoe crabs are an iconic group of marine chelicerates that have an impressive fossil record extending back to at least the Lower Ordovician. Despite their long fossil record andExpand

A 3D anatomical atlas of appendage musculature in the chelicerate arthropod Limulus polyphemus
Limulus polyphemus, an archetypal chelicerate taxon, has interested both biological and paleontological researchers due to its unique suite of anatomical features and as a useful modern analogue forExpand

Xiphosurid from the Tournaisian (Carboniferous) of Scotland confirms deep origin of Limuloidea
Horseshoe crabs are archetypal marine chelicerates with a fossil record extending from the Lower Ordovician to today. The major horseshoe crab groups are thought to have arisen in the middle to lateExpand

Xiphosurid from the Upper Permian of Tasmania confirms Palaeozoic origin of Austrolimulidae
Representatives of Austrolimulidae exhibit the most extreme morphological variation documented within true horseshoe crabs. Relative to the more standard morphologies of paleolimulids and limulids,Expand

On the appendicular anatomy of the xiphosurid Tachypleus syriacus and the evolution of fossil horseshoe crab appendages
Xiphosurida—crown group horseshoe crabs—are a group of morphologically conservative marine chelicerates (at least since the Jurassic). They represent an idealised example of evolutionary stasis.Expand

Pictorial Atlas of Fossil and Extant Horseshoe Crabs, With Focus on Xiphosurida
Horseshoe crabs are an iconic group of extant chelicerates, with a stunning fossil record that extends to at least the Lower Ordovician (~480 million years ago). As such, the group has retainedExpand

Reappraising the early evidence of durophagy and drilling predation in the fossil record: implications for escalation and the Cambrian Explosion
The Cambrian Explosion is arguably the most extreme example of a biological radiation preserved in the fossil record, and studies of Cambrian Lagerstätten have facilitated the exploration of manyExpand
