Lexical Compendium

Wait... what is this? Sometimes I come across a word, phrase, idiom, quote, reference, bit of slang, person of interest, etc that either I don't know or I find amusing, interesting, etc. This is a collection of those items so that I can refer back to them in emails, texts, etc.

thagomizer

A thagomizer is a bit of paleontology jargon referring to the spikes on a stegosaurian dinosaur.

When I was young, the Stegosaurus was my favorite type of dinosaur. I had no idea what the spikes were called until very recently though. I especially didn't know that the word was coined by none other than Gary Larson of Far Side fame.

In 1982, Gary Larson wrote a comic in which a caveman, perhaps in a teaching role, explains to an audience that these spikes were named "after the late Thag Simmons."
