Taxonomic list
• Jerd Spring is CIT 313/M-1157, Padrones Spring is CIT 312: Kelly and Lander 1988
Dougherty also reports an indeterminate antilocaprid from CIT 170, stratigraphically well above the other localities near Padrones Spring
said to be above the Upper Triple Basalt, but actually below it: Kelly and Lander 1988; dated at 14.6 +/- 0.6 Ma and 14.8 +/- 0.8 Ma (KA)
appears to be the type locality of "M. calimontanus" and to be the fauna associated with a "late Miocene marine mollusk fauna at Padrones Spring" (Repenning and Vedder 1961)
