This museum is as outstanding as the Smthsonian NHM and of course the American MNH (NYC) and the Royal Tyrell M. According to the fact sheet, 10,000 soecimens are exhibited at any one time (20 galleries). If you visited prior to 2007, then do yourself a favor and see the new Dinosaurs in Their Time. Remember that if you visit on a weekend, or holiday, you will have to put up with the crowds and many children.
