A 409-million-year-old predatory fish provides unique insights into the early evolution of modern lobe-finned fishes. Crown or modern sarcopterygians (coelacanths, lungfishes, and tetrapods) differ substantially from stem sarcopterygians, such as Guiyu and Psarolepis, and a lack of transitional fossil taxa limits our understanding of the origin of the crown group. The Onychodontiformes, an enigmatic Devonian predatory fish group, seems to have characteristics of both stem and crown…

A basal sarcopterygian fish is described that fills the morphological gap between Psarolepis and higher sarcoptergyians and the presence of eyestalk attachments is reported, showing that this supposedly non-osteichthyan feature occurs in basal sarcoperygians as well as the actinoptergyian-like Australian braincase.

Styloichthys from the Lower Devonian of China bridges the morphological gap between stem-group sarcopterygians (Psarolepis and Achoania) and basal tetrapodomorphs/basal dipnomorphs and provides information that will help in the study of the relationship of early sarcoperygians, and which will also help to resolve the tetrapods–lungfish divergence into a documented sequence of character acquisition.
