Dinosaur Size Comparison Charts

Wikipedia user Colin Douglas Howell has created this spiffy gallery of dinosaur size comparison charts, which is ideal for those planning their next off road velociraptor safari.

Many images feature an intrepid time-travelling tourist, who shows the same nonchalance whether facing a cutesy Juravenator starki:

    Nice chart, but there is no the biggest creature on it (Diplodocus). I was really huge.

    Giant Reptile Brotherhood of Villainy? Would make a good band name perhaps.

    @2 jack: Amphicoelias, if it existed, was quite a bit larger.

    “Blue Guy” looks like the man from the Pioneer plaque.

    Ha, the Diplodocus Hallorum was small compared to the Amphicoelias Fragillimus; Like a 195 ft. long, it’s femur alone would be 12 ft. tall.
