While most of us were sleeping in the wee hours of Monday and Tuesday mornings this week, three exhibit specialists from Academy Studios were busy disassembling and reassembling a full-size cast of a Tyrannosaurus rex skeleton at the Academy. The same crew assembled the skeleton over a year ago in the Altered State exhibit. Now, the T. rex is in the front lobby to make room for upcoming changes in Altered State, and the installation of our first temporary exhibit, Extreme Mammals, which is coming to the Academy in April, 2010. This time around, the crew knew their way around the T.rex so well that they finished in two eight-hour nights, instead of the expected three.
