They’re back—again. (And so are we!) Jurassic Park returned to theaters last Friday, this time in 3D. Sure, Steven Spielberg’s dinosaurs blew us away back in 1993, but paleontology has come a long way since then. How does the movie’s depiction of dinosaurs hold up 20 years later? Which species would look and behave differently if the film were made today? And will any new science rear its head in Jurassic Park IV?
Join us at 3 p.m. EDT on Thursday, 11 April, for a rescheduled live Google Hangout with dinosaur experts Stephen Brusatte, who studies dinosaur evolution at the University of Edinburgh in the United Kingdom, and John Horner, a curator at the Museum of the Rockies in Bozeman, Montana, and the paleontological adviser for all the Jurassic Park movies. In the meantime, leave your questions in the comments below.

John "Jack" Horner is curator of paleontology at the Museum of the Rockies, Montana State University, in Bozeman, Montana. He studies dinosaur behavior and growth, and originally determined that dinosaurs were social creatures that nested in colonies, and later traveled in gigantic herds. He was also the inspiration for the character Alan Grant in the Jurassic Park movies, and was also the paleontological adviser to Steven Speilberg for all the Jurassic Park movies.
Stephen Brusatte is a vertebrate paleontologist at the University of Edinburgh, who specializes in the anatomy, phylogeny, and evolution of dinosaurs. He is particularly interested in the origin and extinction of dinosaurs and the evolutionary transition between dinosaurs and birds.
