Ah, poor Teribus. "Decimate" did not appear as an English word until the 16th century and was derived from the Medieval Latin word "decimatus" which related to tithing, or taking a tenth, nothing to do with punishment or killing. In its earliest uses in English, "decimate" related to taking the tithe more often than it did to the punishment context. "Decimated" today hardly ever relates to the strict sense of killing one tenth and most people who use the word don't use it that way. You cling to it if you like. Maybe Stu could tell us more about dinosaurs like you.
