On this edition of Chicago Tonight’s Field Trip, we take a look at the dinosaur that was king before the T-Rex. Peter Makovicky, Curator of Dinosaurs at the Field Museum, was part of a dig that found a brand new species of dinosaur in 2008. It has taken five years for the research team to uncover the bones and research the skeleton. The Siats Meekerorum is suspected to be the apex predator 100 million years ago. It was 30 feet long and weighed about 4 tons. Makovicky explains why the Siats plays an important role in dinosaur history and how scientists are able to hypothesize about what it looked like.
