sharks are also older than trees.
...kinda?
fossils of several of the earliest known elasmobranchii, like antarctilamna are dated to the early-mid Devonian period. the middle Devonian being when plants decided that they'd finally be trees, after like 70-something million years of just laying around doing nothing.
they weren't really all that shark-like yet, though. and the things that people are saying are "shark-like" from around that time, cladoselache, were holocephali which is what chimaeriformes are, not sharks.
