In this extreme environment, symbiotic sulfur-eating bacteria grew in the gills of the trilobites, providing them with energy. This high diversity in their body types and the ability to adapt to their environment is what made trilobites successful for so long.Apr 11, 2018

What is so special about trilobites?
Trilobites were the first group of animals in the animal kingdom to develop complex eyes. Cambrian Period (about 500 million years ago). Trilobites lived in marine waters. Some trilobites could swim, others burrowed or crawled around on muddy sea floors.
What features did trilobites have?
Trilobita is the most species-rich entirely extinct arthropod group. In trilobites, the hard exoskeleton covering the dorsal body surface and its well marked segmentation (for example, the jointed segments of the thorax) are classic arthropod features. The trilobite exoskeleton was mineralised, constructed of calcite.
Could trilobites still exist?
Unfortunately, trilobites have gone the way of the dinosaurs, having become extinct some 251 million years ago. Despite the hope of some scientists, to date, there have been no confirmed discoveries of living trilobites during the time of man.
How long did trilobites dominate the Earth?
Trilobites existed for nearly 270 million years. Actually, not only did they exist… for the majority of their lengthy stay on Planet Earth, they thrived.
How are trilobite fossils helpful in understanding the distribution of living things throughout Earth’s history?
Q. How are trilobite fossils helpful in understanding the distribution of living things throughout Earth's history? Trilobites lived in all the ancient oceans and in varying depths of water. Trilobites were found worldwide and are signature creatures of the Paleozoic Era.
What’s a trilobite fossil?
trilobite, any member of a group of extinct fossil arthropods easily recognized by their distinctive three-lobed, three-segmented form. Trilobites, exclusively marine animals, first appeared at the beginning of the Cambrian Period, about 542 million years ago, when they dominated the seas.
How did trilobites adapt to their environment?
Trilobites were able to adapt to their environment extremely well. This species had a flat head and long eye stalks, which means it likely lived in the sediment on the ocean floor. Fossils like this give scientists useful clues to what life on Earth was like millions of years ago.
Can scientist bring back trilobites?
Although trilobites roamed the oceans for over 270 million years (longer than dinosaurs), only fossils remain in the modern era. Dr. Allan Drummond, a biochemistry professor at the University of Chicago, set out to bring these extinct marine arthropods into the present day.
Are trilobite fossils rare?
Complete trilobite skeletons are relatively rare, and were probably preserved when the sea floor was buried by mud during major storms. Normally, the membranes that hold the skeleton together will decay and the skeleton will fall apart. The various pieces will be scattered by waves, currents or scavenging animals.
