The 16-foot-tall, 39-foot-long animatronic Tyrannosaurus rex now standing on the lawn outside the entrance to the Museum of Science & History is just a sample of what can be found inside the museum.
"Dinosaurs Unearthed," which opens to MOSH members from 6-9 p.m. Friday and to the general public from 10 a.m. to 4 p.m. Saturday, includes 14 animatronic models of 11 different dinosaurs ranging in size from the 39-foot-long T-rex to the 2.3-foot long-Microraptor.
There are also skeletons of the 14.1-foot-long Huayangosaurus and the 10.8-foot-long Gasosaurus.
"This is the first time animatronics of this scale have been combined with fossils in a exhibit here," said Maria Hane, MOSH's executive director.
The large T-rex outside the museum's entrance wags its tail, turns its head, opens and closes its mouth and makes growling noises, all things the dinosaurs located on the second floor exhibit space also do, making MOSH's second floor rather noisy at times.
There are also a number of interactive components to "Dinosaurs Unearthed." There is a dig table where visitors can dig like paleontologists for fossils embedded within the table.
Consoles featuring models of the Yangchuanosaurs and the Protoceratops feature buttons that allow visitors to trigger the movement of a body part.
The Dinosaur Detective touch screen exhibit quizzes visitors to test their knowledge about dinosaurs. There are also stations offering 3D images and touch screen facts about dinosaur skulls, bones and their digestive process.
In the museum lobby there is an excavation site modeled on the Dashanpu Quarry site in China, which has yielded a number of fossils and skeletons from the Jurassic era.
The exhibit is intended to be educational as well as entertaining, said Alyssa Porter, MOSH's curator.
"Everything you see has science behind it," she said.
The timing of the exhibit is serendipitous for MOSH since this summer will see the release of the movie "Jurassic World," a sequel to 1993's "Jurassic Park" starring Chris Pratt and Bryce Dallas Howard, with Stephen Spielberg as an executive producer.
