Abstract: Jaws... and teeth There are very few fossils that record the earliest history of jawed vertebrates. Fossil remains of crown-group osteichthyans (bony fishes, including tetrapods) are known as far back as the Silurian (418 million years ago), but tracing the osteichthyans any further has proven difficult. Now Botella et al. report the first unambiguous evidence for osteichthyan characters in two previously known Late Silurian fish (423–416 million years old), demonstrating that they are not only the oldest, but phylogenetically the most primitive osteichthyans known to date.
