Meeting Abstract 44.5 Wednesday, Jan. 5 Tail use in primates: balancing the variables MILLER, CE*; SCHMITT, D; Duke University; Duke University charlotte.miller@duke.edu The biomechanical role of the tail during animal locomotion is poorly understood, in part because tails are also often used in other complex non-locomotor behaviors such as signaling. Data are available on the role of […]

Comparing stride local stability during walking and running
Meeting Abstract 44.1 Wednesday, Jan. 5 Comparing stride local stability during walking and running QIAO, Mu*; JINDRICH, Devin; Arizona State University mqiao1@asu.edu Morphology, musculoskeletal physiology, and active control could all potentially contribute to within-stride stability during locomotion. However, to what extent are within-stride movements actually stabilized during unperturbed locomotion? This study sought to characterize within-stride local stability […]
The influence of fossoriality on cranial architecture in caecilian amphibians (Gymnophiona)
Meeting Abstract 43.4 Wednesday, Jan. 5 The influence of fossoriality on cranial architecture in caecilian amphibians (Gymnophiona) MADDIN, H.C.*; WAKE, M.H.; KRISTENSEN, E.; Univ. of Calgary; Univ. of California, Berkeley; Univ. of Calgary hcmaddin@ucalgary.ca Fossoriality, wherein the head is employed as the primary locomotor organ (i.e., head-first burrowing), has evolved multiple times independently within Tetrapoda. Among these, […]
Snail versus crab the biomechanics and evolution of shell ornamentation in Strombus

Meeting Abstract 43.6 Wednesday, Jan. 5 Phylogenetics, evolution, and development of ruminant cranial appendages: insights into hypotheses of homology BRAKORA, K.A.*; DAVIS, E.B.; LEE, A.H.; Department of Integrative Biology, University of California, Berkeley; Museum of Natural and Cultural History, and Department of Geology, University of Oregon; Department of Anatomy, Midwestern University kbrakora@berkeley.edu Recent revisions of ruminant phylogeny […]
Morphological Integration of the Turtle Shell
Meeting Abstract 43.2 Wednesday, Jan. 5 Morphological Integration of the Turtle Shell MELSTROM, K. M.*; ANGIELCZYK, K. D.; University of Michigan; Field Museum kmelstro@umich.edu The turtle shell is one of the most distinctive evolutionary novelties among tetrapods, but there is significant variation in shell morphology and function. In particular, previous research has demonstrated that the presence of […]
Craniodental specialization in notosuchian Crocodyliformes Linking morphology with ecology during the Cretaceous Period
Meeting Abstract 43.3 Wednesday, Jan. 5 Craniodental specialization in notosuchian Crocodyliformes: Linking morphology with ecology during the Cretaceous Period OCONNOR, P.M.*; SERTICH, J.J.W.; STEVENS, N.J.; Ohio Univ; Stony Brook Univ; Ohio Univ oconnorp@ohio.edu Notosuchian crocodyliforms recovered from Cretaceous-age deposits have revealed a level of craniodental diversity not exhibited in extant Crocodylia. Tooth crowns ranging in shape from […]
