(PLATES VI. & VII.) 
NUMBER of restorations of dinosaurian reptiles have been 
recently made by the writer, based upon American specimens: 
which he has personally investigated. Reduced figures of three of 
these restorations have already appeared in this Macazine; namely, 
Brontosaurus and Stegosaurus from the Jurassic, and Triceratops 
from the Cretaceous. Three others of interest are given in the 
present Number; Anchisaurus from the Triassic, Ceratosaurus from 
the Jurassic, and Claosaurus from the Cretaceous. The last is a 
gigantic herbivorous reptile, a typical member of the Ornithopoda, 
and one of the American allies of Iguanodon. The other two are 
carnivorous forms of the order Theropoda, as defined by the writer. 
Ceratosaurus has apparently its nearest European ally in 
Megalosaurus, while Anchisaurus appears most nearly 
related to Thecodontosaurus. 
The three restorations here represented are each based 
upon the remains of a single indi- 
vidual, which were nearly or quite 
complete when found, and apparently 
in the position in which each animal 
died. The skull and the greater part 
of each skeleton were secured, and the 
portions lost are represented in allied 
Fic. 1.—Anchisaurus colurus, Marsh, 3; nat. size. 
From the Upper Triassic Sandstone, Connecticut," U.S.A.
