Noun
Context #1 | Noun

paleontology

Trilobites are extinct marine arthropods that thrived during the Paleozoic era, particularly from the Cambrian to the Permian periods. They are characterized by their three-lobed body structure, which consists of a cephalon (head), a thorax, and a pygidium (tail). Fossil evidence shows that trilobites were diverse and inhabited a variety of marine environments, from shallow seas to deep ocean floors. They played a significant role in early marine ecosystems and are often used as index fossils by geologists to date rock layers. Trilobites have provided crucial insights into evolutionary biology and the history of life on Earth.

Synonyms

extinct arthropod, marine fossil

Examples of usage

  • The trilobite fossils were discovered in a limestone quarry.
  • Paleontologists study trilobites to understand ancient marine environments.
  • Trilobites are recognizable by their distinct exoskeletons and segmentation.
  • The extinction of trilobites marked the end of an era in Earth's history.

Etymology

The word 'trilobite' is derived from the Greek words 'tri-', meaning 'three', and 'lobos', meaning 'lobed' or 'sided'. This nomenclature reflects the distinctive three-lobed morphology of these ancient creatures. Trilobites first appeared during the Cambrian period, around 521 million years ago, and continued to evolve into a wide variety of forms until their extinction approximately 252 million years ago at the end of the Permian period. They were part of a vital group of marine organisms and contributed significantly to the biodiversity of their time. The study of trilobites has helped scientists understand evolutionary processes and the effects of mass extinction events in Earth's history. Their fossils are among the most common and diverse fossil types found, making them invaluable to the field of paleontology.
