Trilobites are an extinct group of marine arthropods that thrived during the Paleozoic Era, particularly from the Cambrian to the Permian periods. By the time the Cretaceous period arrived, trilobites had already been extinct for millions of years, having disappeared around 252 million years ago during the Permian-Triassic extinction event. Therefore, finding trilobite fossils in Cretaceous sediments would be highly unusual and would likely indicate some form of misclassification or unusual geological circumstances.
