Plants are much less complex than animals, so I went with ferns

Ferns are some really old plants! They showed up around 360 million years ago, and at least one species hasn't changed in 180 million years. Turtles came significantly later around 157 million years ago (way before triceratops).

Ferns are about as old as it gets, I think. But turtles... If tortoises weren't around, then what was the earth sitting on? Wouldn't it fall?

Don't worry. The first turtle had to come from somewhere. It's turtles all the way down.
