"Dinosaurs roamed the earth for millions and millions of years. Museum visitors are awed by the massive skeletons/fossils/creatures on display. But how did the fossils of a colossal diplodocus make the 145-million-year journey from the prehistoric plains of Utah to the Smithsonian Museum of today? Acclaimed author and illustrator, Jessie Hartland (How the Sphinx Got to the Museum), beautifully presents this informative and fascinating history of the diplodocus: from its discovery in 1923 in Utah to its arrival in the hallowed halls of this world-famous museum. Essential reading for junior paleontologists"-- Provided by publisher.
