SUPPLEMENTARY NOTES ON 

 FOSSIL SHARKS 



BY 



DAVID STARR JORDAN and CARL HUGH BEAL 



In the Bulletin of the Department of Geology, University of 

 California publications for 1907, the senior writer published a 

 memoir entitled "The Fossil Fishes of California." In this 

 paper, with other matters, there is a record of the species of 

 sharks known from the Miocene deposits of Kern County, 

 California. 



Stanford University has lately received from Mr. Charles 

 Morrice of Bakersfield another large collection of shark's teeth. 

 These were obtained from a hill on the west side of Kern River, 

 about a mile distant from the stream and four miles from Oil 

 City. These were preserved in a fine hard silt. The collection 

 was made by Mr. Morrice at the suggestion or with the aid of 

 Mr. F. M. Anderson of the California Academy of Sciences, 

 Professor Harry A. Millis of Stanford University, Professor 

 W. C. Mitchell of the University of California, and Mr. A. C. 

 McLaughlin of Palo Alto. 



Three other papers have dealt with the Miocene sharks of 

 California. Two of these, by Louis Agassiz, preceded the paper 

 of 1907. Professor Agassiz published in the American Journal 

 of Science and Arts, pp. 272-275, a paper entitled "Notice of 

 Fossil Fishes Found in California by W. P. Blake." This 

 article with a few verbal changes and a page of engravings is 

 reprinted in the appendix to Lieutenant Williamson's "Report on
