Hylonomus lyelli

Hylonomus lyelli

Hylonomus lyelli was an agile, lizard-like animal celebrated as one of the earliest undisputed amniotes in the fossil record. Most specimens were preserved inside the hollowed, sand-choked stumps of giant lycopsid trees, where they became trapped while hunting or seeking shelter. With small, pointed teeth adapted for crushing arthropod carapaces, it thrived in the damp undergrowth of equatorial coal swamps long before the rise of dinosaurs.
