A holomorph approach to xiphosuran evolution: a case study on the ontogeny of Euproops
, 2012 Specimens of Euproops sp. (Xiphosura, Chelicerata) from the Carboniferous Piesberg quarry near Osnabruck, Germany, represent a relatively complete growth series of 10 stages.

The visual system of harvestmen (Opiliones, Arachnida, Chelicerata) – a re-examination [PDF]
, 2016 Background: The visual systems in chelicerates are poorly understood, even though they show strong variation in eye and visual neuropil architecture, thus may provide valuable insights for the understanding of chelicerate phylogeny and eye evolution ...

New insights into the evolution of lateral compound eyes in Palaeozoic horseshoe crabs
, 2019 Vision allows animals to interact with their environment. Aquatic chelicerates dominate the early record of lateral compound eyes among non-biomineralizing crown-group euarthropods.

Journal of Arachnology, 2001 Due to their widespread use as model systems and their reputation as living fossils, horseshoe crabs (Xiphosura) have been studied intensively by physiologists and paleontologists. The close phylogenetic relationship between horseshoe crabs and arachnids might also have been expected to inspire studies of xiphosurans by comparative arachnologists, but ...
