The monotreme echidna is older than this echidna, obviously, seeing as KC's only been doing this since about 2006 or so rather than, you know, 1788.

That said, this Echidna is named after Greece's mythological Echidna, who probably would have shown up in mythology anywhere between 2000-ish and 146-ish BC. Best of luck narrowing that down, unless you're pretty heavily specialized in Greek mythology.
