The permanent exhibition in the new dinosaur hall is twice the size of the previous dinosaur displays, and is presented in two two-story galleries. The hall’s biggest boast is its Tyrannosaurus rex growth series, the first in the world, which presents fossil specimens of the youngest known baby T. rex, a rare juvenile and a remarkably complete young adult. The exhibition also features some 300 fossils, 20 fully articulated skeletons, physical and digital interactive displays and video. Other standouts include a never-before-mounted triceratops, a 68-foot long-necked mamenchisaurus and giant reptiles that lived in the oceans covering what is today California. Two-thirds of the full-body specimens have never been displayed before. 900 Exposition Blvd., downtown, 213.763.3466 Map K15 www.nhm.org
