These early, very primitive synapsids are a primitive group of pelycosaurs collectively called "ophiacodonts".A friend alerted me to an IO9 post, "The First Artificial Sweetener Poisoned Lots of Romans."It's a (very) brief look at some of the uses of lead (Pb) in the Roman world, including the hoary hypothesis that rampant lead poisoning led to the downfall of Rome - you know, along with gonorrhea, Christianity, slavery, and the kitchen sink.
