# TRUE: Sharks are older than trees.

> The claim is basically right. Shark-lineage animals are known from hundreds of millions of years ago, before true trees and forests appeared on land. The caveat is that this refers to the shark lineage, not every modern shark species.

## Claim
Sharks are older than trees.

## Verdict
- Label: TRUE
- Source match: Strong
- Confidence: High
- Score: 90
- Meaning: Shark-lineage fossils predate the first true trees by tens of millions of years.

## Copy-Ready Comeback
FactPage check: TRUE. — sharks, as a lineage, are older than trees.

## Bottom Line
The claim is basically right. Shark-lineage animals are known from hundreds of millions of years ago, before true trees and forests appeared on land. The caveat is that this refers to the shark lineage, not every modern shark species.

## Evidence Lines
1. Shark lineage is very ancient - Shark-like cartilaginous fishes appear in the fossil record roughly 400+ million years ago, often cited around 450 million years ago for early shark relatives.
2. Trees came later in the Devonian - The first forests and tree-like plants are associated with the Devonian, roughly 390–360 million years ago. That is later than early shark-lineage fossils.
3. Lineage, not living species - The claim is broad. It is true for the shark lineage, not for every living shark species. Many modern shark species evolved much more recently.
