Trilobites are considered extinct because they disappeared from the fossil record approximately 252 million years ago at the end of the Permian period, during the largest mass extinction event in Earth's history. Despite their once widespread presence in marine environments, they could not adapt to the dramatic changes in climate and ocean chemistry that followed. No living descendants have been found, and their unique characteristics, such as their segmented bodies and compound eyes, are only preserved in fossil form. Thus, their complete absence from contemporary ecosystems solidifies their status as extinct.
Trilobites became extinct about 250 million years ago, in the Mesozoic Era.
Trilobites are extinct but they were marine animals.
The trilobites went extinct during the mass extinction at the end of the Permian period.
Trilobites have been extinct for a long time; there are none left for us to take care of.
The Trilobites.
Trilobites are extinct marine organisms that are often used to date rocks. They were widespread and diverse in the past, making them a useful tool for understanding the age of rock formations through biostratigraphy. Trilobites existed for over 270 million years before becoming extinct.
Trilobites lived for 280 million years before they became extinct, from the Cambrian to the Permian.
Scientists believe that trilobites reproduced sexually. These prehistoric and extinct creatures were a type of arthropod that probably laid eggs. Trilobites lived about 250 million years ago.
If you mean trilobites, they have been extinct for millions of years.
You don't. Trilobites are extinct and are only found as fossils.
