Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Yanornis is an extinct genus of Early Cretaceous bird, thought to be closely related to the common ancestor of all modern birds. One species, Yanornis martini, has been described from fossils found in the Jiufotang Formation at Chaoyang, Western Liaoning province, PRC, and as of 2004 five specimens were known. The age of the Jiufotang Formation is somewhat unclear, but most estimates point towards an early Aptian origin, about 125-120 million years ago. It was the size of a large pigeon, had a long skull with about 10 teeth in the upper and 20 teeth in the lower jaw, and was both able to fly and walk well, having a well-developed U-shaped furcula (wishbone). It ate fish, and in the associated adaptations shows remarkable convergent evolution to the unrelated enantiornithine Longipteryx. Furcula and teeth, on the other hand, are more like in the enantiornithine Aberratiodontus.
