The oldest shark teeth are from the Early Devonian, about 410 million years old. These are without a doubt sharks, although different species than exist currently. The earliest fossil of a plant engaging in this evolutionary strategy is a 12 meter tall palm-like plant from China. It dates back, again, to the Early Devonian, but less than 400 million years ago.

Which means the first toothed sharks predate the first plant which could be called a tree by 10 million years.

Sharks are older than the rings of Saturn!
