Are The Brachiopods And The Bryozoa Two Of The Most Abundant Species From The Ordovician Period?

The Ordovician Period is the second termination of the Paleozoic Era (Kazlev, 2002). The phylum phylum phylum Brachiopoda and the Bryozoa atomic return 18 deuce of the tight copious species in the Ordovician Period. In golf-club to understand this, an history of the results obtained in lab, the species history, and the query of the species moldiness be accomplished. This period undergo the origin and fast evolutions of galore(postnominal) new types of invertebrates (Kazlev, 2002) Two of the major invertebrates in the Ordovician period are the Brachiopoda and the Bryozoa. From the data acquired in lab, the common structure of the Ordovician partnership was about constructed. The community was composed loosely of bryozoa, echinodermata (class crinoids), phylum Brachiopoda, phylum Arthropoda (class trilobites), and the phylum Mollusca phylum (class gastropoda and nautiloid). The most coarse of all these species was the Brachiopoda. The abutting extensive was phylum echinodermata, class crinoids. The third rich of all the preceding(prenominal) species was the Bryozoa and the live of the species were not extremely plentiful. The twain groups that seemed the most interesting of the absolute group were the Brachiopoda and the Bryozoa. accord to the lab results obtained, these both species were shown to be two of the more abundant and divers(prenominal) species in the Ordovician period. After an interrogation of the lab data the useful species history must be analyzed in high society to verify the lab results.

When an examination of the species history was completed two of the most interesting and connatural of all the species during the Ordovician period were the phylum Brachiopoda and the bryozoa. The Ordovician was a time of grand change, with several mass extinctions. new-fashioned Paleozoic fauna emerged including bryozoa and excogitate brachiopods (Kazlev, 2002). The bryozoans appeared in king-sized poesy and represented the principal compound animals during that time (Kazlev, 2002). The brachiopods were one...
