THE GEOLOGICAL RECORD 





Bavaria; but as they are, even then, fully developed, though 

 small, there must have been a long series of intennediate forms 

 which probably reached back to the Triassic if not to the 

 Permian era. 



Fig. 63. — Skeleton of Pterodactylus spectahilis. 

 From the Upper Jurassic of Bavaria. Nat. size. This early form has teeth and a 

 very short tail, and the body was not larger than that of a sparrow. (B.M. 

 Guide.) 



The illustration of the skeleton of one of these early forms 

 on this page is of the natural size (Fig. 63), Tt shows the 

 greatly elongated fifth finger to which the wing-membrane was 

 attached. In this form there were small teeth in the jaws, and 

 the tail was very short.
