Cephalic biomechanics underpins the evolutionary success of trilobites

Jorge Esteve, Jordi Marcé-Nogué, Francesc Pérez-Peris & Emily Rayfield
Arthropods (i.e. insects, spiders, crustaceans, myriapods and others), are the most successful Phanerozoic animals. The group are characterised by the possession of a segmented body, jointed limbs and a hard cuticle that is episodically moulted. One highly successful, but now extinct, group of arthropods are the trilobites. Trilobites underwent episodic moulting (ecdysis), and most trilobites possess facial sutures, lines of weakness in the cephalon, via which the exuviae is shed and the animal emerges. However,...

Data from: Dryopithecine palaeobiodiversity in the Iberian Miocene revisited on the basis of molar endostructural morphology

Josep Fortuny, Clément Zanolli, Federico Bernardini, Claudio Tuniz & David M. Alba
Extensive fieldwork at Abocador de Can Mata (NE Iberian Peninsula) has uncovered a previously unsuspected diversity of catarrhine primates in the middle Miocene (12.5–11.6 Ma) of Europe. However, the distinction of the great ape genera Pierolapithecus and Anoiapithecus from Dryopithecus—supported by craniodental differences—has been disputed by some authors. Here we revisit the diversity of great apes (dryopithecines) from the Iberian Miocene based on molar 3D endostructural morphology (relative enamel thickness, enamel distribution, and enamel-dentine junction...

SI dataset S1 - knuckle-walking biomechanical strategies

Julia Arias-Martorell, Angel Zeininger & Tracy Kivell
African apes engage in a distinct form of locomotion called knuckle-walking, but there is much ambiguity as to when and how this locomotor behaviour evolved. This study aims to elucidate potential differences in knuckle-walking elbow posture and loading in African apes through the study of trabecular bone. Using a whole-epiphysis approach, we quantified variation in trabecular structure of the distal humerus of chimpanzees, western lowland gorillas, and mountain gorillas in comparison to orang-utans, siamangs and...
