I thought I'd stick with the vague etymology theme I've had going on and talk about a link that friend of the blog Galadriel linked me to a while back. Thank you, Galadriel! Or, should I say, hantanyel.
If, like me, you went through a serious dinosaur phase as a kid, you probably remember that the stegosaurus is the one with the big plates sticking up off his back and a spiked tail. And if, like me, you went through a serious Far Side phase several years later, you probably remember that Gary Larson drew strips about cavemen, like, all the damn time.
Well, apparently paleontologists really took a shine to this particular comic
because the term thagomizer has become an accepted (if informal) synonym for stegosaurus' tail spikes. Seriously, is there anything better than a scientist with a great sense of humor? Okay, there's plenty of things, but... they're still pretty cool.
I love that the article is careful to point out that "The fate of Thag Simmons notwithstanding, stegosaurs and humans did not exist in the same era." Suck it, creationists. (Assuming that Leviticus will let you.)
