Today, we ’ re taking a deep dive into one of the fascinating creatures ever to live: the Trilobite!

Описание: Facts about Trilobites 🦐 (ancient marine animals):

🌊 What Were Trilobites?

Trilobites were extinct marine arthropods (relatives of crabs, spiders, and insects).

They lived in the oceans for about 270 million years.

Their name means “three-lobed” because their bodies were divided into three long sections.

🕰️ When Did They Live?

Trilobites appeared around 521 million years ago during the Cambrian Period.

They went extinct about 252 million years ago during the Permian mass extinction.

🧩 Body Structure

Their bodies had three main parts:

Head (Cephalon)

Middle body (Thorax)

Tail (Pygidium)

They had a hard outer shell (exoskeleton) made of calcite, which fossilized easily.

👀 Amazing Eyes

Trilobites had some of the first complex eyes in animal history.

Their eyes were made of crystal-like calcite lenses, which helped them see underwater.

🍽️ Diet

Some trilobites were scavengers, feeding on dead organisms.

Others were predators or filter feeders.

🏃 Movement & Defense

They crawled on the sea floor and some could swim.

Many trilobites could roll into a ball like a pill bug to protect themselves.

🦕 Fossil Importance

Trilobites are among the most common and important fossils.

Scientists use them to help date ancient rock layers.
