Without any ballyhoo, the museum launched a new attraction in June called Dinosaur Encounters, in which actor-puppeteers don lifelike T. rex or triceratops suits and spend 20 minutes demonstrating how scientists believe baby dinos behaved. Usually they work with interpreter-handlers, but sometimes they just roam free and meet their public. Which is how a museum-goer's video of a grunting, bemused, 7-foot-tall and 14-foot-long T. rex inspecting babes-in-arms and other humans at close range came to be posted on MySpacetv on Thursday. "Real Live Dinosaur" shot to No. 1 on MySpace's daily video chart, attracting more than 215,000 viewers by early evening -- far outstripping "Cindy and Heidi Bare It All." That clip from TMZ featured stills of Crawford and Klum yachting au naturel, their modesty preserved by strategically placed black bars.
