Case 9F. — Flabellaria, leaves of a palm which grew in the 
Eocene epoch near Green River, Wyoming. Also, leaves of Acer, 
or maple, and other modern plants. 
Xumviuliies — There are abundant and characteristic fossils of 
this period. They are shells of a Rhizopod, and in Europe and 
Africa form limestones many thousand feet in thickness. 
Case 10. — Among univalve mollusks many modern types 
will be recognized — Turritella, Natica, CerWmini, Strombns,2cs\A 
others. 
Fishes belonging to the order of Teleosts, or osseous fishes, are 
illustrated by many specimens from the Green River beds — Prisca- 
rara, Diplomysfus, etc. These are of modern types and related 
to the perch, herring and the like. 
Sharks of enormous size also existed. Teeth of the Carcha- 
rodon are common fossils, and specimens may be seen in this case. 
Floor of Hall 36, Pedestal 13.— A restoration showing 
the jaws of Carcha 7 'odon and within these, for comparison, the 
jaws of a modern shark. The ancient Carcharodo 7 i was probably 
50 to 70 feet in length. 
Pedestal 12.— Restoration of Hadrosaurus from the Upper 
Cretaceous of New Jersey. This was a huge land reptile, 28 feet 
in length, allied to the Iy^ua 7 iodon, It was probably a vegetable 
feeder, and able to stand and walk after the manner of birds. 
Pedestal 14. — Cast of the skull of a Mastodo?i from the 
Miocene beds in the Sewalik Hills, India. Behind it, a femur of 
the same animal, and head and femur of Diprotodon (cast). 
Pedestal 15. — Head of the Dinotheriiun (cast). This was 
a huge animal with a skull three feet long, herbivorous, and re- 
markable for two long tusk-like teeth, projecting downwards. It 
combined the characteristics of the elephant, hippopotamus, tapir, 
and dugong. A cast of its femur may be seen near by. 
Pedestal 16. — A restoration of the skull of the Elephas 
ganesa, one of seven species of elephants existing during the 
^Miocene epoch in India. It is remarkable for the length of its 
tusks, those of this specimen being ten feet long. 
Pedestal 17. — Restoration of a skeleton of Dmoceras, from 
Wyoming. This was a five-toed Ungulate of elephantine size, but 
having no proboscis, and probably like the rhinoceros in its 
habits. It is marked by three pairs of protuberances on its skull
