There are alot of widespread fossil organisms from the Paleozoic;
-Brachiopods
-Bryozoa
-Trilobites
-Corals
-Crinoids
-Gastropods
-Nautaloids/Cephalopods
-Ostracods
-Scolecodonts
Once you get to devonian you may be able to find shark teeth.
After the Carboniferous, You can find plants, insects, and (rarely) reptiles.
Hope this helped!
Fossils that are found over a wide area.
Fossils that are widespread geographically are commonly referred to as cosmopolitan fossils. These fossils are found in multiple locations around the world, indicating a broad distribution during the time period in which they were alive.
Precambrian rocks are older than Paleozoic rocks, dating back to about 4.6 billion to 541 million years ago, while Paleozoic rocks were formed from 541 to 252 million years ago. Precambrian rocks lack fossils, while Paleozoic rocks contain abundant fossil evidence of early marine life. Additionally, Paleozoic rocks mark the beginning of complex life forms, whereas Precambrian rocks mainly consist of simpler organisms.
The fossilized remains of the trilobite, an extinct marine arthropod, are found on almost every continent. These creatures thrived during the Paleozoic Era, particularly in the Cambrian period, and their widespread distribution is attributed to both their diverse habitats and the extensive geological processes that have shaped Earth's continents over millions of years. Trilobite fossils are commonly discovered in sedimentary rock formations, making them one of the most recognizable and studied fossils globally.
Yes, index fossils are special fossils that act as geological tools enabling comparison in time of a range of geological units and environment. Normally, they are selected using certain attributes such as the fossil should be widespread, abundant, fast evolving, and independent of their environment.

Fossils that are the most useful for correlation tend to be found in various types of rocks, are widespread, and easy to recognize. One rock type where fossils are found is sedimentary rocks.

Trilobites are common fossils throughout the Paleozoic.
Three types of marine animals in the Paleozoic Era were trilobites, brachiopods, and archaeocyathids.

Index Fossils
Trilobites were a group of organisms preserved as fossils in early Paleozoic rocks that are now extinct. However, some groups that were present during that time and still exist today include corals, brachiopods, and cephalopods like nautiloids.

Index Fossils. They are very important tools for geologists and used in paleontology and stratigraphic studies.
