The Incredible Evolution of Trilobites

Описание: Journey back 520 million years to witness trilobites—Earth's most successful animals that dominated ancient oceans for over 300 million years. These armored arthropods with compound eyes pioneered sophisticated vision systems using calcite lenses that eliminated optical distortion. From the Cambrian Explosion through the devastating Permian extinction, 20,000 trilobite species evolved across every marine ecosystem, outlasting dinosaurs' entire reign.

Discover Isotelus rex—the largest trilobite ever found at 72 centimeters long—prowling Ordovician seafloors as a formidable predator. Explore revolutionary adaptations: enrollment defense strategies that rolled bodies into protective spheres, specialized eyes ranging from enormous deep-water organs to reduced shallow-water versions, and sophisticated mating behaviors preserved in Olenoides serratus fossils showing ancient reproduction.

Witness trilobite diversity spanning filter feeders, active hunters, sediment sifters, and scavengers occupying every ecological niche. Learn how their segmented exoskeletons—reinforced with calcium carbonate—provided flexibility and protection that enabled unprecedented evolutionary success. From tiny fingernail-sized species to giant Acaste reaching 43 centimeters, these marine arthropods demonstrated adaptability unmatched in Paleozoic life.

Uncover fossil evidence revealing complex behaviors, healed predator injuries proving survival through molting vulnerabilities, and specialized appendages functioning as claspers during reproduction. Explore how trilobite evolution responded to mass extinctions, competing fish predators, and changing ocean chemistry until the Great Dying ended their 300-million-year reign. Paleontology research continues discovering new species in ancient marine ecosystems preserved across every continent.
