Biography
Hammer was born in Detroit, Michigan and attended Wayne State University where he earned a bachelor's degree and masters in Zoology and completed a doctorate in Paleontology. As a student researcher, he was introduced to the study of fossil vertebrates in Antarctica by his advisor, Dr. John Cosgriff.
Contributions to paleontology
Hammer was part of eight expeditions to Antarctica between 1977 and 2017.[6][7] In 1991,
synapsids fossils nearby, investigated the site and found the femur of a large theropod dinosaur exposed from the rock.[6] The quarry later produced a skull with a unique head crest that was described in 1994 as belonging to a new genus and species, Cryolophosaurus ellioti
.
Hammer also collected the partial remains of a sauropodmoropha dinosaur. When the specimen (a partial foot, leg and ankle bones) was later described and a new genus and species named, Glacialisaurus hammeri, it was to honor Dr. Hammer for his contributions to vertebrate paleontology and Antarctic research.[8][9]
