Is it the crocodile or alligator? I'm obviously not a zoologist so i'm not sure if i phrased that question correctly, but you get the idea.

OK, this is a bit complex. First of all, there are different species of alligator and different species of crocodile, depending on what you consider a species. At least there are different variants on each. I don't know which of the two is more ancient, I suppose they share a common ancestor. I imagine that the coelocanth is more ancient than either, though.

I was going to say some sort of deep sea tubeworm. Certainly the nautilus is older than this stuff...
