What were trilobites
Trilobite. Trilobites are extinct marine animals belonging to class Trilobita, a subdivision of the phylum Arthropoda, which includes the familiar insects, crabs, centipedes, millipedes, spiders, scorpions, and horseshoe crabs, among others. The name “trilobite” is derived from the three longitudinal divisions, or lobes, of the trilobite body.trilobite limbs that have been found, all were built to this basic pattern. So it is likely that much of the extravagant va-riety in trilobite design was played out upon the hard calcite of the exoskele-ton. Abundant fossils give us a good idea of the variety of form adopted by these extinct animals. Trilobites appeared rather suddenly Trilobites were ancient marine arthropods with distinctive three-lobed body and intricate exoskeleton. Credit: Kevin Walsh. A set of compound eyes were present in the majority of Trilobites, but others were visually impaired. Three anatomical segments were made up of Trilobites, 2 of which were located on either side of a longitudinal axial ...

Reef building sponges called stromatoporoids and corals suffered losses and stromatoporoids finally disappeared in the third extinction near the end of the Devonian.
