Raymond Rogers is the chair of the Geology Department at Macalester College in St. Paul, Minnesota.  He is an earth scientist who studies ancient sedimentary environments and the fossil record of vertebrate animals. His talk, "The Amazing Dinosaur Fossil Record of Madagascar", will focus on the highlights of his Madagascar work.
His current research focuses on reconstructing the terrestrial settings that were home to dinosaurs and their compatriots.  Ray also explores how bones and teeth become fossils, focusing both on the ecology and chemistry of fossilization.  His work on rocks and fossils over the years has taken him far afield, and he has ongoing research projects in Madagascar, Montana, and Argentina.  Recent discoveries and reports of an amazing fossil mammal and bird from the Cretaceous of Madagascar made by Rogers and his colleagues were highlighted in the news just this past year.  Previous discoveries of note include the radiometric age of the oldest dinosaurs (based on the dating of a volcanic ash bed in Argentina) and evidence for cannibalism in dinosaurs (based on amazing traces on fossil bones in Madagascar). 
Ray received his undergraduate degree in geology from Northern Arizona University, his master’s degree in geology from the University of Montana, and his PhD in geology from the University of Chicago.  He joined the faculty of Macalester College in 1997, and has been chair of the Macalester Geology Department for 15 years.  Ray is also an Adjunct Professor in the Department of Geology and Geophysics at the University of Minnesota, and a Research Associate at the Field Museum of Natural History in Chicago and the Denver Museum of Nature and Science.  Here is the link to Ray’s website:   https://rogerslab.weebly.com/
