I made this, just for the heck of it. The critters are, from left to right: OMNH 53062, the holotype of Sauroposeidon proteles , with a reconstructed skeleton grayed in; HM XV2, a fibula of Brachiosaurus brancai , which represents the largest known individual of Brachiosaurus ; HM SII, the nearly complete mounted composite skeleton of Brachiosaurus brancai in Berlin; a 20-foot-tall, world record giraffe;
