From the Detroit Zoo's site:
Forty lifelike animatronic dinosaurs that snarl and move – and some that spit – have taken up residence at the Detroit Zoo to provide a mega-dose of Vitamin Z for visitors of all ages. Dinosauria, presented by Kroger and Michigan Education Savings Program, runs through Labor Day.It'll be a good prep for the Jurassic World movie opening June 12!
Enter a veritable “Zoorassic Park” as you travel back in time along a lush, winding, 5-acre DinoTrail recreating prehistoric life. Enormous primeval creatures lurk at every turn, including adult dinosaurs, youngsters and even a nest with eggs and hatchlings.
Dinosauria is open daily 9:30 a.m. to 5 p.m. (until 8 p.m. Wednesdays during July and August). Tickets are $5 with Zoo admission for visitors ages 2 and older and are available at main admissions, or the Dinosauria ticket booth.
Hope to see you there :)
