or Dinosaur, 28 feet in length. It was probably a vegetable 
feeder, and able to stand and walk after the manner of birds. 
SOUTH AND EAST WALLS. — Large slabs and casts 
showing tracks of reptiles made in the Triassic period in the 
Connecticut River Valley. Little is known about these animals, 
except so much as can be learned from their foot-prints. The 
Brontnzoum was a three-toed animal, probably at least 14 feet 
in height, with a stride of over 3 feet. All were probably Dino- 
saurs, living at a somewhat earlier period than those of the 
Western States. 
HALL 59. 
FIRST CASE RIGHT. — A large number of beautifully pre- 
served remains from the lithographic slate beds of Solenhofen. 
They include some of the earlier Insects, Crustacea, resembling 
the modern lobster and king crab, and remains of large squids. 
In some of the latter the imprint of the whole animal is shown 
while others are represented only by the fossils known as Belem- 
nites, which are simply the internal skeleton or a portion of it. 
FIRST AND SECOND CASE, LEFT. — Ammonites, re- 
markable for size and complexity of suture. Many specimens 
are shown, including the genera Cardioceras, Arietites, Gramnio- 
ceras, etc. Some of the Arietites are 3 feet in diameter. The 
sutures, of some specimens have been painted to bring out the 
markings. Many specimens of Nautilus and allied Cephalopods. 
Ammonites were especially abundant in this age. 
SECOND AND THIRD CASES, RIGHT.— Remains and 
restorations of Ichthyosaur ^ Pliosaur^ Plesiosaur, and other ma- 
rine reptiles of the age. The two former often reached a length 
of 40 feet. They had stout bodies, short necks, enormous eyes, 
long teeth and fin-like tails and paddles. The latter were their 
organs of locomotion. The huge eyes and teeth indicate that 
they were predatory and voracious animals, their food being 
probably fishes and other reptiles. The Plesiosaur was a more 
graceful animal, with long neck, small head and powerful pad- 
dles, but in habits similar to the preceding. All had many fish- 
like characters. ’ I]
