There are a few notable dig sites that have very well preserved fossils from this period. The best sites of the Cambrian period are:
Maotianshan Shales (Chengjiang) 515 Mya Yunnan Province, China Sirius Passet 518 Mya Greenland Emu Bay Shale 513 Mya South Australia Kaili Formation513-501 Mya Guizhou province, south-west China Blackberry Hill~510-500 Mya Central Wisconsin, US Wheeler Shale(House Range) 507 Mya Western Utah, US Burgess Shale 508 Mya British Columbia, Canada Kinnekulle Orsten and AlumShale 500 Mya Sweden ÖlandOrste and Alum Shale 500 Mya Sweden

These creatures are far apart in time. Trachodon is from the Late Cretaceous and the Wooly Mammoth are from Pleistocene period.
Fossils from the Silurian Period are between 443.7 and 416 million years old.
Index fossils (also known as guide fossils, indicator fossils or zone fossils).
Index fossils are the fossils of short-lived species which, because of their short lives, can be used by scientists to identify the age of the rock strata in which they're found. (For example, if you know a certain species only lived in the Cambrian period, and you find some fossils of this species in some rock, then you know the other fossils you find in that rock must also have come from the Cambrian period.) Some examples of species that left behind index fossils, and their related historical periods, are:Billingsella corrugagta - Cambrian period, Palaeozoic eraCactocrinus multibrachiatus - Mississippian period, Palaeozoic eraScaphites hippocrepia - Cretaceous period, Mesozoic eraNeptunea tabulata - Quarternary period, Cenozoic eraSee the links below for more examples and info.
Yes somebody did find fossils
Cambrian period
Precambrian is a geologic period that extends as back as 4.500 million years ago. Fossils are very rare from that period of time.
To find fossils, you have to go underground, and also, if you have defeated the elite four then you are more likely to find more fossils.
about 4600 million years ago
