Age of trilobites.

The Ordovician and Cambrian Periods are referred to as the "age of invertebrates", with trilobites abundant. In this period, brachiopods became more abundant that the trilobites, but all but one species of them are extinct today. In the Ordovician, large cephalopods developed as predators of size up to 10 meters. Here in the Marble Mountains abundant and well-preserved fossil trilobites can be found dating from the early Cambrian geologic age, or roughly 518 million years old--some of Earth's most ancient identifiable animals with hard parts--those wonderful arthropod trilobites that as a group survived for nearly 300 million years before their eventual ...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.

I was assigned to write a research paper on “the Age of Trilobites” Questions to consider include when trilobites emerged and how long they survived, how many different species of trilobites existed and what evidence do we have of this, where on Earth did they live and how do we know, what caused their final extinction, etc.

Abnormal trilobites represent a primary means of understanding how a group of wholly extinct euarthropods responded to, and recovered from, injuries and developmental or genetic malfunctions (Owen, Reference Owen 1985; Babcock, Reference Babcock 1993, Reference Babcock, Mikulic, Landing and Kluessendorf 2007; Bicknell and Pates, Reference Bicknell and Pates 2020).

There were dramatic worldwide sea-level changes and oceanic turnovers (exchanges of bottom waters and surface waters) resulting in a moderate level of extinctions during the Period.
