Guiyu oneiros
The Earliest Known Sarcopterygian
Guiyu oneiros was an early sarcopterygian that lived
about 423 million years ago in the Late Silurian and was 
discovered in Qujing, Yunnan, China. It was about 30 cm 
long, with a streamlined body and sharp teeth. Its skull 
resembles those of sarcopterygians, whereas its cheek 
region is more actinopterygian-like, and the spine in front 
of the pectoral fin resembles those seen in placoderms, 
acanthodians, and chondrichthyans. As a representative 
fossil of the Xiaoxiang Vertebrate Fauna, Guiyu oneiros is 
preserved nearly complete and helps bridge the 
morphological gap between osteichthyans and other 
early jawed vertebrates.
