The story unlocks once you make your call.
True. True! Sharks: ~450 million years. Trees: ~385 million.
Where it came from
It sounds wrong because we picture trees as part of the scenery the animals arrived into.
Why it’s true
The earliest shark-like scales in the fossil record are around 450 million years old. The first true trees, such as Wattieza and Archaeopteris, appeared roughly 385 million years ago, in the Devonian.
Sharks have come through several mass extinctions since.
