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.

Although researching has provided a definition for the word trilobite there does not seem to be any reference as to why one would be referred to as a trilobite. A trilobite is an extinct arthropod from Paleozoic times of which the skeleton is divided into three parts.
There are as many different fields in Paleontology as there are topics to study. There are paleontologists who lets say, specialize in therapod dinosaurs; but then there may be paleontologists who study Trilobite anatomy. Also, Paleontologists can specialize in a certain period in time, suck as the Cretaceous, or the Ordovician.
The trilobite is able to survive droughts because it is eggs can survive millions of years before hatching.
A phacops fossil is the preserved remains or trace of an extinct genus of trilobite, a group of marine arthropods that lived during the Paleozoic era. These fossils are typically found in ancient marine sediments and are characterized by their distinctive appearance, with segmented bodies, compound eyes, and a hard exoskeleton.
