Neil writes, ” I got the tattoo shortly after SJ Gould’s death. I had settled on the design before he died so it’s not quite an homage but I did lift the picture from Wonderful Life. The original figure is by Marianne Collins I believe. The Cambrian “c” was added later, my long-range plan was/is for a whole paleozoic sleeve but I ran out of funding soon. I’d also like to get more ‘stem’ taxa one of these days.”
