PARAHIPPUS.

(Osborn, 1918) Crochet complicated in dp 2, 3 , simple in dp 4 . 



This specimen is very important as the genotype of Parahippus, and is noteworthy as recorded from a high geologic 

 level while belonging to Parahippus as the genus is now understood. We must await the discovery of permanent teeth 

 for the proper definition of the specific characters. 



Referred to this species are (W. D. M.) Amer. Mus. 13919, 13943, 14322.

Horizon and locality. — (Sellards, p. 82) "Early in November, 1915, the Geological Survey received notice through 

 Mr. E. B. Epps of the discovery of fragments of vertebrate fossils from a well on the Griscom plantation about 15 miles 

 north of Tallahassee (Sec. 32, T. 3, N, R. I. E.) . . .After passing through the surface materials which consist of coarse 

 red, clayey sands, 15 or 20 feet in thickness, the well from which these fossils were obtained enters the gray phosphatic

sands and clays characteristic of the Alum Bluff formation and terminates at the depth of about 60 feet in hard lime- 

 stone, probably of the Chattahoochee formation. The vertebrate fossils are imbedded in the gray phosphatic sands and 

 are believed to have come chiefly from a depth of from 25 to 50 feet." 



Type. — Fla. State Geol. Surv. Coll. 5084. (Sellards, p. 83) "Among the fossils from the Griscom plantation is a 

 horse represented by a permanent tooth from the right upper jaw, probably M 1 , two lower cheek teeth, an astragalus 

 and a first median and a first lateral phalanx. This horse is referred to the genus Parahippus and to the new species P. 

 leonensis. A horse, probably the same species, is represented in the collection from the fuller's earth mine at Midway
