Dig a Dinosaur – Brachiosaurus: Be a Paleontologist! Dig and excavate the skeleton of a mysterious prehistoric animal and then assemble the skeleton to form a dinosaur model from this science set. Was a genus of sauropod dinosaur that lived in North America during the Late Jurassic, about 154–153 million years ago. It was first described by American paleontologist Elmer S. Riggs in 1903 from fossils found in the Colorado River valley in western Colorado, United States. Riggs named the dinosaur Brachiosaurus altithorax; the generic name is Greek for “arm lizard”, in reference to its proportionately long arms, and the specific name means “deep chest”. Brachiosaurus is estimated to have been between 18 and 21 meters (59 and 69 ft) long; weight estimates range from 28.3 to 58 metric tons (31.2 and 64 short tons). It had a disproportionately long neck, small skull, and large overall size, all of which are typical for sauropods. Atypically, Brachiosaurus had longer forelimbs than hindlimbs, which resulted in a steeply inclined trunk, and a proportionally shorter tail.
Contains a cardboard display platform with fun facts, a plaster block with an embedded Brachiosaurus skeleton (measures about 28 cm long when assembled), soft wax (for positioning the joints), a digging tool and a brush. Carefully dig away the plaster to find the hidden dinosaur bones.
