Meeting Abstract S3-1.1 Saturday, Jan. 5 Vertebrate diversity and phylogeny across the fish-to-tetrapod transition COATES, M. I.; Univ. of Chicago, Chicago mcoates@uchicago.edu The popular idea of the fish-to-tetrapod transition covers a series of changes to the gnathostome body plan: mid-line fins are lost; digited limbs replace paired fins; a sacrum links vertebrae to hips; gills are reduced; […]

The deep homology of the tetrapod limb Combining fossil and genetic datasets
Meeting Abstract S3-1.4 Saturday, Jan. 5 The deep homology of the tetrapod limb: Combining fossil and genetic datasets. DAVIS, Marcus C; Kennesaw State University mdavi144@kennesaw.edu The evolution of tetrapod limbs from fish fins was a significant functional shift. But how significant was this shift in terms of morphology and gene regulation? The fossil record provides insight into […]

Metabolic and osmoregulatory challenges of emersion in fishes
Meeting Abstract S3-1.6 Saturday, Jan. 5 Metabolic and osmoregulatory challenges of emersion in fishes. WILSON, JM*; CHEW, SF; IP, YK; CIMAR, Porto, Portugal; Nanyang Tech. Univ., Singapore; National Univ. Singapore, Singapore wilson.jm.cimar@gmail.com The climbing perch (Anabas testudineus), combtooth blenny Lipophrys pholis, and weatherloach Misgurnus anguillicaudatus are three examples of teleost fishes that have adapted to terrestrial conditions. […]
Historical evolution of early tetrapod movement
Meeting Abstract S3-1.3 Saturday, Jan. 5 Historical evolution of early tetrapod movement PIERCE, SP*; HUTCHINSON, JR; CLACK, JA; The Royal Veterinary College, UK; The Royal Veterinary College, UK; University Museum of Zoology, Cambridge, UK spierce@rvc.ac.uk Conceptualizations of the evolution of tetrapod locomotion have changed drastically in the past 50 years. When early tetrapod fossils were first discovered, […]
Diversity and Disparity of the vertebrate feeding apparatus across the invasion of land
Meeting Abstract S3-1.2 Saturday, Jan. 5 Diversity and Disparity of the vertebrate feeding apparatus across the invasion of land ANDERSON, P*; FRIEDMAN, M; RUTA, M; Univ. of Massachusetts, Amherst; Univ. of Oxford, UK; Univ. of Lincoln, UK panderson@bio.umass.edu When vertebrates first colonized land, about 370 Mya, they encountered a world full of new dietary resources requiring radical […]
Brave New Propagules Terrestrial Embryos of Aquatic Fish
Meeting Abstract S3-1.5 Saturday, Jan. 5 Brave New Propagules: Terrestrial Embryos of Aquatic Fish MARTIN, K.L.*; MORAVEK, C.L.; CARTER, A.L.; Pepperdine Univ.; Pepperdine Univ. ; Charleston Southern Univ. kmartin@pepperdine.edu Species within many lineages of teleost fishes reproduce terrestrially, despite lacking the key evolutionary innovation of the amniotic egg. In contrast with shelled eggs of reptiles and birds, […]
