Why exactly do dinosaurs matter?

What can we learn by studying Tyrannosaurus rex's banana-size serrated teeth; or by figuring out that duck-billed dinosaurs likely traveled in herds; or by determining that Spinosaurus could swim?

Paleontologist Kenneth Lacovara answers these questions in his new book "Why Dinosaurs Matter" (Simon & Schuster/TED) released Sept. 19, and now a lucky few will be able to win a free copy of his book by answering a trivia question about dinosaurs.

Live Science is interviewing Lacovara — the dean of the School of Earth and Environment at Rowan University in New Jersey, as well as director of the university's Jean and Ric Edelman Fossil Park — on Facebook Live at 1 p.m. EDT on Tuesday (Sept. 26).

We will ask a trivia question about dinosaurs at the beginning of the interview. Five people, chosen at random from all of those people who answer the question correctly in the Facebook comments, will receive a free copy of “Why Dinosaurs Matter.”

The contest rules are below. Best of luck to all our dinosaur fans out there! Don't forget to follow Live Science on Facebook and Twitter for updates on this contest and other live-video events.
