San Diego State University Advisor Dr. Stephen Schellenberg, Dr. Tom Deméré Friday, December 10th, 2010 -------------------------------------------------------------------------------- ABSTRACT The study of shark evolution and relationships has always suffered from the fact that sharks possess cartilaginous skeletons and rarely, if ever, leave behind skeletal remains in the fossil record. Because of this, the evolutionary history of sharks has been cobbled together with the teeth...

LiDAR and Field Observations of Earthquake Slip Distribution for the Central San Jacinto Fault -- Barrett Salisbury, M.S. Candidate, Department of Geological Sciences, San Diego State University, Advisor Dr. Tom Rockwell -- We mapped the tectonic geomorphology of 80 km of the Clark strand of the San Jacinto fault (SJF) to determine slip per event for the past several surface ruptures. We identify 203 offset features from which we make over 560 measurements using B4 LiDAR imagery,...

The early Miocene Quechan volcanics, SE California, U.S.A.: slab-window or continental-margin arc volcanics? -- Holly Olsen, M.S. Candidate, Department of Geological Sciences, San Diego State University, Advisor Dr. Gary Girty -- Located between Indian Pass and Picacho State Recreation Area, SE California are widespread exposures of an ~4 to 1.2 km thick early Miocene volcanic and epiclastic unit.
