Interesting paper in Science: The Role of Ammonites in the Mesozoic Marine Food Web Revealed by Jaw Preservation, subtitled: "How they revolutionized the Mezozoic Marine Food Web" (Thanks, Angélique.) I like the notion of revolutionary ammonites, chewing their way through the establishment.
One day I'll have to dust off my graphics pad and draw Che Ammonite: beret, scruffy beard, bandana. But, eh, today is not that day. Today is the day I buckle down and write this essay I've been promising someone, on the work of a Famous Writer. (Which I'll happily tell you about, if and when I ever get it done.)
