Brontosaurus Skeleton 3D instructions

Step 1: Join spine halves with upper pelvis.

Step 2: Add hips to upper pelvis.

Step 3: Add lower hips and attach ischium.

Step 4: Add cervical vertibrae to neck.

Step 5: Add ribs to spine.

Step 6: Add transverse processes to spine.

Step 7: Attach front legs to shoulders and add to spine.

Step 8: Assemble skull pieces and attach to neck.

Step 9: Add hind legs to pelvis and attach tail.

Step 10: (optional) Add Gastralia to ribs.

Where to add them is a bit of a guess since there is no fossil record of the connective tissue for this floating structure. We glue the tips of the gastralia to the tips of the ribs.
