Data from: 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 for fossil arthropod groups. To assist the study and documentation of this iconic taxon, we present a 3D atlas on the appendage musculature, with specific focus on the muscles of the cephalothoracic appendages. As L. polyphemus appendage musculature has been the focus of extensive study, depicting the muscles in 3D will facilitate a more complete understanding thereof for future researchers. A large museum specimen was CT scanned to illustrate the major exoskeletal features of L. polyphemus. Micro-CT scans of iodine-stained appendages from fresh, non-museum specimens were digitally dissected to interactively depict appendage sections and muscles. This study has revealed the presence of two new muscles: one within the pushing leg, located dorsally relative to all other patella muscles, and the other within the male pedipalp, located in the modified tibiotarsus. This atlas increases accessibility to important internal and external morphological features of L. polyphemus and reduces the need for destructive fresh tissue dissection of specimens. Scanning, digitally dissecting, and documenting taxa in 3D is a pivotal step towards creating permanent digital records of life on Earth.

Supplemental data for: Three-dimensional kinematics of euchelicerate limbs uncover functional specialisation in eurypterid appendages
<p>Sea scorpions (Eurypterida; Euchelicerata) explored the extreme limits of the aquatic euchelicerate body plan. Indeed, the group contains the largest known marine euarthropods. Inferences on eurypterid life modes—in particular walking and eating—are commonly made by comparing the group to horseshoe crabs (Xiphosura; Euchelicerata). However, no models have been presented to test these <span>hypotheses</span>. Here, we reconstruct prosomal appendages of two exceptionally well-preserved eurypterids <i>Eurypterus tetragonophthalmus</i> and <i>Pentecopterus decorahensis </i>and kinematically model the flexure and extension of these appendages in 3D. We compare these models to 3D kinematic models of <i>Limulus polyphemus</i> prosomal appendages. This comparison highlights that the examined eurypterid prosomal appendages could not have effectively moved prey items to the gnathal edges, and therefore would not have emulated the motion of a <i>L. polyphemus</i> walking leg. It seems that these eurypterid appendages were primarily used to walk or grab prey and other appendages would have moved prey for mastication. Such 3D kinematic modelling highlights how eurypterid appendage morphologies placed substantial limits on their function, suggesting a high degree of specialisation, especially when compared to horseshoe crabs. 3D kinematic modelling of these extinct groups also presents an innovative approach to understanding the position of these animals within their respective paleoecosystems.</p>
