History
Trilobites are extinct marine arthropods that lived during the Paleozoic Era, from approximately 521 to 252 million years ago. They were incredibly diverse, with thousands of species inhabiting the world's oceans. Their fossil record is extensive, providing invaluable insights into ancient ecosystems, evolution, and geological time periods. This particular fossil represents a snapshot of life from a long-vanished marine environment.
Facts
Trilobites are considered index fossils, meaning their presence and specific forms help geologists date rock layers. Their exoskeletons were made of calcite, which facilitated their preservation. The discovery of trilobites played a significant role in the development of paleontology and evolutionary theory, challenging earlier beliefs about the history of life on Earth. They are highly sought after by collectors and researchers.
Value Fact
The market for trilobite fossils is driven by rarity, preservation quality, and species identification. Well-preserved specimens, especially those with complete bodies or unusual features, command higher prices. Educational institutions and private collectors often compete for prime examples, creating consistent demand. Prices can range from tens to thousands of dollars depending on the factors mentioned.
