Blunt-nosed leopard lizards live in arid
areas of central California. They can
typically be found in open, flat areas with few
Im not exactly sure how long blunt-nosed
leopard lizards have been around, but we can make
an educated guess based on some facts.
(1) Blunt-nosed leopard lizards occur only
in the San Joaquin Valley, and are thought to
have evolved there from other desert leopard
lizards. This makes them what scientists call
(2) They live in arid (desert)
(3) The San Joaquin Valley for millions of
years was under a vast ocean. Only in the past
2 million years, after being cut off from the
ocean through geologic events, did it dry out and
become desert. This tells us that the environment
that they need to survive, in the place where they
evolved, only came into being, at most, 2 million
years ago. Based on these three observations,
we can conclude that blunt-nosed leopard
lizards have probably not been around for more
than 2 million years.
By the way, the taxonomic name of blunt
nosed leopard lizards was changed in 1993 from
Gambelia silus to Gambelia sila. This has to
do with some boring conventions of Latin grammar.
It may help you if you want to do more research on
this species to have the updated scientific name.
