Poleta Formation, Montezuma Range, Esmeralda County, Nevada
is an exceedingly rare specimen of a new genera and species only
recently described in 2005. Teresellus is among the early lower
Cambrian trilobites. Soon after trilobites appeared in the lower
Cambrian, they rapidly radiated among the primary trilobites in
the Cambrian, the Redlichiida, Ptychopariida, Agnostida and Corynexochida.
Poleta Formation is important to understanding of the Cambrian paleogeography
of western Laurentia.
