THEODOR, J. M.; VAN VALKENBURGH, B. ; FRISCIA, A.; ROWE, T.: CT scan based quantitative comparison of respiratory turbinates in the Canidae and Felidae The maxilloturbinates, bony scrolls within the anterior nasal chamber of most mammals, function to warm inspired air and conserve water during ventilation. Variation in maxilloturbinate structure among species is poorly understood, […]

MCBRATNEY-OWEN, B. M. ; OLSEN, B. R.; Harvard Medical School; Harvard Medical School: Mousehead Revisited – Microevolutionary Variation of the Cranial Base in Three Inbred Mouse Strains In order to investigate the genetic architecture and molecular development of morphological variation, the magnitude of morphological divergence must first be investigated among the variation being studied. This […]

GOSWAMI, A; University of Chicago, IL and Field Museum, Chicago, IL: Morphological Integration in the Mammalian Skull: The Influences of Phylogeny, Function, and Ontogeny Recent genetic and developmental studies have produced compelling hypotheses of the importance of trait correlations to morphological evolution. However, these hypotheses have never been tested with a broad, comparative data set […]

HOLLIDAY, Casey; Ohio University: Homology of extant archosaur jaw muscles: soft tissues and their osteological correlates. Divergent morphological specializations of extant groups and fragmentary descriptions of soft- and hard-tissue topology have hampered understanding of the evolution and homology of archosaur jaw musculature, hindering interpretation of feeding evolution in non-avian dinosaurs. A similarity test was conducted […]
