Paul Sereno was born in Aurora, Illinois on October 11, 1957. He was the second oldest of six children: he has an older brother , Marty, and four younger sisters- Joan, Anne, Margaret and Sara - in that order.

As a kid, Paul was mischievous and often caused trouble in school. Paul's mother, Rena was an art teacher and all of the children were encouraged to experiment in art and ask lots of questions about things.

In high school Paul played French Horn in the marching band and began to paint seriously. By the time he went off to Northern Illinois for college Paul had decided to major in biology and art. It wasn't until he was almost ready to graduate from college that he decided to study paleontology.

During a trip to the American Museum of Natural History in New York with his brother Marty, Paul got to see the 'behind the scenes" activity that surrounded the science of fossils: bones, technical drawing, biology and travel. He was hooked! He turned his artistic talent to recording the fossil record and got a doctorate in geology at Columbia University.He has been teaching at the University of Chicago for twelve years.

The 2000 Expedition to Niger will be the eighth expedition that he has led. "I think this upcoming expedition will be the most discovery-filled of them all! I am looking forward to the great fossil beds that we will be hunting in. I think that many discoveries await us. I want to find as much of Nigersaurus, our newest dinosaur, as possible. I will also be looking for any new dinosaurs or other animals to fill in our picture of the dinosaur era in Africa."
