"Living Fossils" in Our Reef Tanks

[Enigma]

A show I'm watching on TV right now (about an isopodish looking thing called a "nautilus") has me thinking . . . Are there any critters commonly stocked in our tanks that are relatively unchanged from prehistoric times?

Edit: the Nautalus is apparently a cephalopod.

You're correct. They're 400 million years old: they apparently have Devonian origins (so says Google). Cool! I haven't seen any in my system.

Diatoms also.

As for diatoms . . . I have had those!

I think cyano is something like 3 billion years old, makes sense as to why it's so tough to get rid of!

Horseshoe crabs. Creepy things... 450Million years old or so?

Cyano is as old as the earth itself :P I think it started its journey when the earth became a "live-able" planet (as far I can remember reading it somewhere).
