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

The Ordovician Period is the second gunpoint of the Paleozoic Era (Kazlev, 2002). The phylum phylum phylum Brachiopoda and the Bryozoa atomic number 18 deuce of the around abundant species in the Ordovician Period. In golf-club to understand this, an score of the results obtained in lab, the species history, and the examination of the species must be accomplished. This period experient the origin and fast evolutions of many new types of invertebrates (Kazlev, 2002) Two of the major(ip) invertebrates in the Ordovician period are the Brachiopoda and the Bryozoa. From the info acquired in lab, the general structure of the Ordovician partnership was roughly constructed. The community was be well-nighly of bryozoa, echinodermata (class crinoids), phylum Brachiopoda, phylum Arthropoda (class trilobites), and the mollusca phylum (class gastropoda and nautiloid). The most abundant of all these species was the Brachiopoda. The abutting abundant was phylum echinodermata, class crinoids. The third gear abundant of all the preceding(prenominal) species was the Bryozoa and the rest of the species were not highly plentiful. The two groups that seemed the most interesting of the entire group were the Brachiopoda and the Bryozoa. According to the lab results obtained, these two species were shown to be two of the more(prenominal) abundant and divers(prenominal) species in the Ordovician period. After an examination of the lab data the effective species history must be analyzed in order to verify the lab results.

When an examination of the species history was ideal two of the most interesting and simila r of all the species during the Ordovician p! eriod were the brachiopoda and the bryozoa. The Ordovician was a time of vast change, with several plenteousness extinctions. new-fashioned Paleozoic fauna emerged including bryozoa and articulate brachiopods (Kazlev, 2002). The bryozoans appeared in large numbers and represented the principal colonial animals during that time (Kazlev, 2002). The brachiopods were one...
