Petrified fossils commonly preserve organisms such as trees, plants, and some types of marine life, particularly those with hard parts like shells and bones. Common examples include ancient wood, ferns, and mollusks. These fossils form when organic material is gradually replaced by minerals, turning them into stone over time. The process usually occurs in environments with high mineral content, such as riverbeds or volcanic ash deposits.
Five types of fossils found in rocks are petrified fossils (minerals replace organic matter), mold fossils (imprint of an organism), cast fossils (mold filled with minerals), carbon films (thin layer of carbon residue), and trace fossils (evidence of organism's activity).

Fossils of marine animals like ammonites, trilobites, and brachiopods are commonly found in sedimentary rocks. Plant fossils such as leaves, stems, and pollen are typically found in rocks as well. Fossils of dinosaurs and other land-dwelling animals are more commonly found in sedimentary rocks that were formed in terrestrial environments.
A. Foraminiferans are indeed fossils of protozoans. They are single-celled organisms with shells, commonly found in marine environments, and their fossilized remains are used in various geological studies. Trace fossils, on the other hand, represent the activity of organisms rather than the organisms themselves, while ammonites are extinct mollusks and not protozoans.
Dinosaur fossils have been found in various parts of Arizona, including sites near Tucson, the Petrified Forest National Park, and the Grand Canyon. Some notable dinosaur fossils found in Arizona include those of Dilophosaurus and Sonorasaurus.
Petrified fossil is an organism that has been converted into stone. Silica, iron and copper minerals can be commonly found in petrified fossils.

Fossils are most commonly found in sedimentary rocks. These rocks form from the accumulation and cementation of sediment, which helps preserve the remains of organisms over time. Sedimentary rocks often provide the ideal conditions for the formation and preservation of fossils.

anywhere
Petrified fossils can be found in sedimentary rocks, particularly in areas with ancient riverbeds, lakes, or volcanic ash deposits. Common places to find petrified fossils include national parks, quarries, and coastal cliffs. It's important to note that collecting fossils may be regulated, so it's best to check local rules and regulations before attempting to find or collect them.

I'm unable to provide images, but you can try searching the virtual petrified wood museum's website or other online resources for images of trilobites and crinoid stems. They are both ancient marine creatures that lived millions of years ago and are commonly found as fossils in petrified wood and other sedimentary rocks.
