Meeting Abstract 32.3 Friday, Jan. 4 Observing skeletal evolution in real time: preliminary results from an artificial selection experiment in laboratory mice. ROLIAN, C*; DOWHANIK, A; KRUEGER, C; HALLGRIMSSON, B; University of Calgary cprolian@ucalgary.ca Vertebrates show tremendous diversity in the morphology of the postcranial skeleton. This diversity is the long-term result of evolutionary forces acting on population-level […]

Multiple origins of the adipose fin and the morphological diversification of novel vertebrate appendages
Meeting Abstract 32.1 Friday, Jan. 4 Multiple origins of the adipose fin and the morphological diversification of novel vertebrate appendages STEWART, TA; Univ. of Chicago tomstewart@uchicago.edu Adipose fins are appendages found between the dorsal and caudal fins of some teleost fishes. Their evolutionary history is poorly understood, as is their function. These fins are often regarded as […]

Getting inside the head of ancient ray-finned fishes
Meeting Abstract 32.4 Sunday, Jan. 5 08:45 Getting inside the head of ancient ray-finned fishes GILES, S*; FRIEDMAN, M; University of Oxford, UK; University of Oxford, UK sam.giles@earth.ox.ac.uk The endocranial cavity is found inside the skull of vertebrates, and represents the space in which the brain and associated nervous tissues sit. During fossilisation, these soft tissues rot […]
