The animal probably had no hairy covering to enable it to endure 
a rigorous climate as did the mammoth. It inhabited chiefly the 
temperate regions of the United States, where its remains are 
found in abundance. 
Pedestal 7. — Skeleton of the Irish Deer, from Limerick, 
Ireland — a Post- Pliocene deer of a great size, the bones of which 
are found in marl beneath peat beds in Ireland and England. 
The antlers of this animal have a spread of seven feet, and its 
height was nearly eight feet. 
Floor Case A. — Bones of fossil reptiles of Wyoming. Des- 
cribed under Jurassic fossils p. 25. 
Floor Case B. — Skull of Titanotherium ingens. Collected in 
the Bad Lands of South Dakota by the Museum Expedition of 
1898. This is one of the largest and finest Titanothere skulls ever 
found. The animal was somewhat rhinocerous like in its habits 
and in size probably reached a length of fourteen feet and height 
of eight feet. 
Case 11. — Complete series of cervical vertebrae except -the 
atlas, and five dorsal vertebrae of the Titanotherium individual 
whose skull is shown in Floor Case B. 
The long spinous processes show that the creature had a 
large hump over the fore limbs caused by the development of 
muscles required to support the heavy skull. 
Other Titanotherium bones. Skulls of Mesohippus, Lepto- 
meryx etc,, mammals more or less contemporaneous with the 
Titanotherium. 
Hall 35. Case 12. — Group of Daemonelix or “Devil's Cork- 
screws." Series showing probable development of Dae 7 nonelix, 
Daemonelix is found in great quantities over the plains and 
among the strata of Northwestern Nebraska. Their exact nature 
is problematical but the most probable view is that which con- 
siders them fossil aquatic plants. ' According to another theory 
they are casts of ancient mole burrows. The series shown is 
thoroughly representative. 
Case 13 A. — Vertebrate fossils of the Tertiary period. Fossil 
turtles shown, include many carapaces from Nebraska, South 
Dakota, and South Carolina ; also turtle eggs from France. 
The Cetacea, or whales, of this period, are illustrated by 
vertebrae of the Zeuglodon, These animals were probably seventy
