Meeting Abstract 19.1 Saturday, Jan. 4 10:15 The radiation of a living fossil: Jaw morphology of tree squirrels ZELDITCH, M.L*; LI, J.; TRAN, L.A.P.; SWIDERSKI, D.L.; Univ. of Michigan, Ann Arbor zelditch@umich.edu The dynamics of adaptive radiations have captured much attention recently, but equally interesting are groups famed for their morphological conservatism, i.e., living fossils. Some living […]

Olfactory Evidence on the Terrestrial Origins of Monotremata
Meeting Abstract 19.6 Saturday, Jan. 4 11:30 Olfactory Evidence on the Terrestrial Origins of Monotremata SIMON, R.V.*; ROWE, T.B.; The University of Texas at Austin; The University of Texas at Austin rvsimon@utexas.edu Whether Monotremata originated as a terrestrial or aquatic clade is a hot debate that so far has revolved around the interpretation of fragmentary Early Cretaceous […]
Macroevolutionary relationships between size and diet in mammals
Meeting Abstract 19.4 Saturday, Jan. 4 11:00 Macroevolutionary relationships between size and diet in mammals. PRICE, S. A.*; HOPKINS, S.S.; Univ. of California, Davis; Univ. of Oregon saprice@ucdavis.edu Living mammals exhibit remarkable variability in body mass, spanning eight orders of magnitude from the bumblebee bat (~1.3g) to the blue whale (~160 tonnes). Due to the high energy […]
Macroevolutionary dynamics of scapula shape and locomotor behavior in Carnivora
Meeting Abstract 19.3 Saturday, Jan. 4 10:45 Macroevolutionary dynamics of scapula shape and locomotor behavior in Carnivora SLATER, GJ; Smithsonian Institution SlaterG@si.edu The mammalian scapula is a large, flat bone, forming the proximal end of the forelimb. Because the scapula has no bony articulation with the axial skeleton, the forelimb attaches to and supports the trunk through […]
