AGES OF ROCK

I drew this image for the Cruisin’ the Fossil Freeway book and exhibit I did with Dr. Kirk Johnson. It’s also a very fun and catchy little song I co-wrote with Russell Wodehouse on the CD of the same name. I truly believe that everyone should know the geologic ages of our planet. They should be taught in kindergarten right alongside the ABCs as far as I’m concerned. I’m dead serious about this folks. And hey… they’re surprisingly easy to memorize and having this t-shirt in your wardrobe will make it even easier.
