## Curiosity - Did you know?

Despite its permanent residence in Jurassic-themed toy sets, *Dimetrodon* went extinct nearly **40 million years** before the first true dinosaur set foot on Earth. Even more surprising: as a synapsid, this sail-backed hunter sits firmly on the same evolutionary lineage that would eventually give rise to mammals. Trace the family tree far enough back, and *Dimetrodon* turns out to be biologically closer to a human being than to a crocodile, an iguana, or a *Tyrannosaurus rex*. The next time you spot one standing next to a Triceratops on a toy shelf, you'll know with complete scientific confidence that the pairing is off by approximately **230 million years**.
