This is kind of sad, actually. It’s a slick website from a guy in Utah who claims to have discovered pre-Cambrian dragons. Browse around his gallery, and it’s clear that what he’s got are pictures of random rocks, and that he’s seeing shapes in them like one sees shapes in the clouds. He reminds me of Ed Conrad.
His name is Mike Hallett, so of course this period of gigantic dragons is called the Hallettstoneion. He has also written a book, which has to be seen to be believed. I swear, I think it’s actually written in crayon. Here’s a sample, in case you’d really rather not download a 40MB pdf.
Ouch. I hope his family gets the poor man some help.
