The bronto-size exhibit filled the Miami Science Museum with some of the rarest dinosaur fossils on the planet in a sensational show that made its U.S. debut in our own back yard. It boasted a whopping 14 of the reptilian behemoths' mounted skeletons, as well as an impressive array of pristinely preserved feathered dinosaur and bird fossils hailed as the missing link between the meat-eating dinos and the earliest bird. The undisputed star was an 85-foot fossilized skeleton of Mamenchisaurus jingyanesi, one of the longest-necked beasts to have ever trod the Earth. The length of two school buses, the gargantuan creature was featured in the "round-up" scene in the Jurassic Park sequel The Lost World and was the favorite of local students visiting the show during public school tours. The museum even built an interactive playroom where the sandbox set could unleash their inner paleontologists, freeing mesmerized parents to roam the enlightening boneyard on their own.
