Trilobite fossils are most probably the exoskeleton of an animal. Abandoned when the animal shed its shell to grow a new one as part of the growth process. A collection of abandoned shells could then be winnowed by ocean currents and piled up as a large group in an eddy. Such winnowing of shells is a common marine process.
Because, similar fossils could be found on different continents, in rocks of the same age.

In the Allegheny Plateau, you might find fossils of ancient marine life such as trilobites, which thrived in the ocean that once covered the region. Additionally, plant fossils like coal, indicative of the area's extensive prehistoric forests, are common. Lastly, you could encounter fossils of early amphibians or reptiles, reflecting the transition of life from water to land during the late Paleozoic era.
trilobite fossils are worth commonly around $60- $80. but depending on the size could be worth more or less.
Trilobites were animals like horseshoe crabs without the shell. If they died and became covered with dirt almost immediately, they could become fossils. As the dirt hardened and became rock, if minerals replaced the organic materials, then the corpse of the animal became a fossil.

Crocodiles could be considered to be "living fossils" as they have survived on Earth from the time of the dinosaurs.
if you have dimond you have to use explorer kit
By definition, we could say all three fossils are 'ancient'. Fossils provide an ancient record of plants and animals.

Fossils are principally found in sedimentary rocks and also in some metamorphic rocks of sedimentary origin.
