    I'm wondering where most of the fossils are displayed, how much rock excavation was necessary for collection purposes, and even the lateral extent of the canyon formations moving away from GC. Wonderful demonstration you've provided, thank you~

    I'm not trying to be obnoxious here but how did they know there was anything to see and how did they know eyes would let them see? How did they know they needed eyes and how did they know how to develop them? Amazing.

    14:07 They rode mountain bikes for a LONG time apparently.

    The reason sponges are looked down upon is because they are self-absorbed...
