Introduction to Paleontology - Period 1
It was still just Cutter standing in front of the class when he began this week’s class, even though he was extremely excited about this week’s class topic, “Good morning,” he began, “this week we’re going to be looking at trilobites,” he said excitedly, “Trilobites form one of the earliest known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period, roughly 521 million years ago and they flourished throughout the lower Paleozoic before they began to decline and became extinct in the devonian period. The only surviving Trilobite at this time was the Preotida and then that became extinct during the mass extinction event of the Permian Period,” he explained.
“ Trilobites were among the most successful of all early animals, existing in oceans for almost 270 million years, with over 22,000 species having been described. By the time trilobites first appeared in the fossil record, they were already highly diversified and geographically dispersed. Because trilobites had wide diversity and an easily fossilized mineralised exoskeleton and they left an extensive fossil record. Because of the trilobites, this has led to important studies in biostratigraphy, paleontology, evolutionary biology and plate tectonics. Trilobites evolved into many ecological niches; some moved over the seabed as predators, scavengers or filter feeders and some swam where they ate plankton and others crawled onto land. The largest trilobites were more than 70 centimetres (28 in) long and may have weighed as much as 4.5 kilograms (9.9 lb).” Cutter concluded “for the rest of the class I would like you to work on yourmoddable worksheets and as always I am around to answer any questions that you may have,”
