The Miolabis californicus identified by Maxson is sourced in other literature to the Tick Canyon Formation (which is not limited to Tick Canyon). The Tick Canyon specimen is one of seven known species of Miolabis
(as of 2008; see Kelly and Stewart in Contributions in Science, No. 516, Natural History Museum of Los Angeles County). Miolabis is a member of the family Camelidae.
"Maxson 1928" is also known as "Maxson 1930."
The Mint Canyon beds, typically exposed in Mint Canyon seven
miles northeast of Saugus, California, were described by Dr. W.S.W. Kew
in Bulletin 753 (1924) of the United States Geological Survey. In 1919
during the course of geologic mapping of this region by Dr. Kew, fossil
vertebrate remains were found at several localities. The types represented
in the collection were recorded in Kew's paper in a provisional list
submitted by Dr. Chester Stock. However, no detailed study was made of
this material. Further mammalian remains have been recently secured
from the Mint Canyon formation by Mr. Thomas Clements during geologic
study of the Tejon Quadrangle.
In view of the geologic position of the Mint Canyon beds,
intercalated in a series of marine formations of the Pacific Coast,
marine province, the terrestrial fauna secured from these deposits is
not only important in establishing the age of the Mint Canyon but also
furnishes a basis for comparing the Tertiary record of this region with
that of the Great Basin to the east. Opportunities to correlate the Tertiary
marine record with the terrestrial record of the Great Basin and of the
Great Plains on the basis of land vertebrates are of infrequent occurrence
and warrant in the present instance a careful survey of the Mint Canyon
