*Struggles to resist urge to answer Raak's question with "Yes". Just succeeds.*
[Raak] My answer to Inkspot's first question may be interpreted to mean that, when they were alive (which, clearly, from my answer to your first question, they no longer are) they were individual, living organisms. I trust this is clear.

[Inkspot] Yes.

[Boolbar] Yes!
Boolbar wins by a head from Inkspot! The answer is indeed Archaeopteryx.
I was hoping someone would go for Pterodactyl first, so that I could come back with a witty remark about how I thought that was a verse form, but never mind. I pass the Chair in Jurassic Studies over to Boolbar, with compliments.
