based on an examination of previous restorations in connection with a study of the excellent plates which have been published of the fossils themselves.[1] Two specimens have been discovered; one being now in the British Museum, the other in the Berlin Museum. They were both found in the lithographic slates of Solenhofen, in Bavaria, a formation of the Jurassic period, and, together, furnish the more important details of the structure of this reptilelike bird.
This restoration, therefore, while doubtless inaccurate
