Trilobite phylum.

The trilobites (Phylum Arthropoda) are known to have lived exclusively in marine water and during palaeozoic era, i.e. no freshwater forms have ever been found and theyIn addition, the phylum Arthropoda contains the extinct subphylum Trilobitomorpha. This group is made up of the trilobites, the dominant arthropods in the early Paleozoic seas (541.0 million to 251.9 million years ago). Trilobites became extinct during the Permian Period (298.9 million to 251.9 million years ago) at the end of the Paleozoic Era. Like many invertebrate animals living today, including crustaceans, spiders and insects, trilobites were arthropods, belonging to the phylum Arthropoda. Geologists know that they were marine animals because of the rocks in which they are found and the other types of fossils associated with them.Fossil trilobite Ogygopsis Ogygopsis was one of the trilobites that abounded ...

Trilobites were a member of what is far and away the largest phylum of animals, Arthropoda, with well more than a million described species of out of a total of perhaps 5 to 10 million extant, comprising around 80% of all animal species ( Ødegaard, 2000 ).
