In summary it may be said that the Dinosaur remains are 

 mostly confined to beds from 26 to 29, although occasionally 

 remains are found lower. The bones are usually nearly perfect, 

 though in some localities pieces of the more delicate spines are 

 broken away. The clay usually preserves bones much better 

 than the sandstone.
