RELATIONSHIPS OF THE INVERTEBRATES TO THE VERTEBRATE FAVNAL 

 ZONES OF THE PLIOCENE JAUALITOS AND ETCHEGOIN FORMATIONS AT 

 COALING A , CALIFORNIA 



BY J. 0. NOMUND 



(Abstract) 



The work of Professor Merriam has shown that the invertebrate and verte- 

 brate faunal zones have a rather definite relationship in several of the Mio- 

 cene and Pliocene formations near Coalinga, California. This is well shown 

 in the Jacalitos and Etchegoin formations. Invertebrate faunal zones have 

 been located in the type section of the Etchegoin, which are correlated with 

 those south of Coalinga, including the Mya Zone, or uppermost Etchegoin. 

 The vertebrate faunal zones are placed with reference to these zones. 



Discussion 



The vertebrate fauna, which was correlated with the Mya Zone by Mr. Nom- 

 land, appeared to Dr. J. C. Merriam to be possibly of Pleistocene age and to 

 have been derived from terrace material instead of from the Etchegoin forma- 

 tion. The bones of a large, highly developed Equus, which is not certainly 

 known in the Pleistocene, and of a large deer of the Elk type have never been 

 found in America in beds older than the Pleistocene. Some of the camel bones 

 are possibly from older. Dr. Merriam congratulated Mr. Nomland on the work 

 clone in the correlation of the vertebrate and invertebrate faunal zones of this 

 Coalinga district. 



CLIMATIC ZONES IN THE PLIOCENE OF THE PACIFIC COAST 

 BY J. P. SMITH 



{Abstract) 



The climate of the Eocene of the Pacific coast was tropical or semi-tropical 

 even as far north as Alaska. Similar conditions prevailed during the Oligocene 

 at least as far north as Puget Sound. During the Lower Miocene the climate 

 was mild-temperate north to Washington, while in the Upper Miocene it was 

 warm-temperate. During the Lower Pliocene almost sub-boreal conditions 

 prevailed as far south as Eel River, Mendocino County, California. Middle 

 California had a climate during this time that was much as. it is today. South- 

 ern California was warm-temperate, as is attested by the character of the 

 Fernando fauna. The climate of the Upper Pliocene appears to have been 

 cooler than that of the Lower, as is shown by the character of the faunas 

 from southern California. 



MARINE TRIASSIC INVERTEBRATE FAUNA FROM NEW ZEALAND

The most typical Upper Triassic section of New Zealand occurs on South 

 Island, near Nelson and near Nugget Point. The latter section consists of
