2016- Jacques Gauthier at Science on Saturdays

On October 15th, Jacques Gauthier will present “Birds are Living Dinosaurs/Dinosaurs are Stem Birds.”

Tastes like chicken you say - or should it be tastes like apatosaurus? Come listen to Prof. Jacques Gauthier tell us how we know the dinosaurs didn’t really all disappear, they just learned to fly.

Time: Demonstrations by Synapse of Yale Scientific Magazine from 10am - 11am; Talk from 11am - noon. 

Location: Sterling Chemistry Laboratory, 225 Prospect Street

About Jacques Gauthier: Gauthier is a vertebrate paleontologistcomparative morphologist, and systematist, and one of the founders of the use of cladistics in biology.  Currently he is a Professor of Geology and Geophysics and Ecology and Evolutionary Biology and Curator of Vertebrate Paleontology and Vertebrate Zoology at Yale University. His master’s thesis, the content of which was published in 1982, is a classic work on the paleontology and phylogeny of the lizard clade Anguimorpha that remains a core reference for morphological research on Xenosauridae and Anguidae in particular. His PhD thesis constituted the first major cladistic analysis of Diapsida, as well as arguing for the monophyly of the dinosaurs. He followed this with an important paper on the origin of birds from theropods.  This was the first detailed cladistic analysis of the theropod dinosaurs, and initiated a revolution in dinosaur phylogenetics, in which cladistics replaced the Linnaean system in the classification and phylogenetic understanding of the dinosaurs.  More recently, he has argued together with Kevin de Queiroz for replacing Linnaean taxonomy with the PhyloCode.  In addition to his theoretical work on systematics and taxonomy, Gauthier continues to study the anatomy and relationships of diapsids, particularly lepidosaurs. His lizard work currently focuses on Scincomorpha, following on a career-long interest in the unusual clade Xantusiidae. He is a principal investigator on the National Science Foundation-funded effort to reconstruct the phylogeny of lizards and snakes (Squamata) using gross anatomy and molecular structure, building on his earlier work in collaboration with Richard Estes and Kevin de Queiroz, which established the most widely accepted phylogeny of the group.
