CO OZNACZA SŁOWO TRILOBITE
Trilobit
Trilobity są dobrze znaną skamieniałą grupą wymarłych stawonogów stawowych tworzących klasę Trilobita. Trilobity tworzą jedną z najwcześniejszych znanych grup stawonogów. Pierwsze pojawienie się trylobitów w skamielinach definiuje bazę etapu atdańskiego okresu wczesnobarwskiego i rozkwitły w całej dolnej wieży paleozoiku, zanim zaczęto rozciągnąć się na wygaśnięcie, gdy podczas dewonu wszystkie trylobity z wyjątkiem proetydy zmarł. Trilobity zniknęły w końcu w masowej wymierze na końcu Permian około 250 milionów lat temu. Trilobity były jednymi z najskuteczniejszych dla wszystkich wczesnych zwierząt, poruszających się po oceanach przez ponad 270 milionów lat. Zanim trylobity pojawiły się po raz pierwszy w skamielinach, były już bardzo zróżnicowane i geograficznie rozproszone. Ponieważ trylobity miały szeroką różnorodność i łatwo skamieniałego egzoszkieletu, pozostawiono po sobie ogromny skamieniałość, a około 17 000 znanych gatunków obejmowało czas paleozoiku. Badanie tych skamieniałości przyczyniło się do znacznego wkładu w biostratygrafię, paleontologię, biologię ewolucyjną i tektonię płyt.
