Connection between plate tectonics and dating fossils
Relative Time Relative time is the sequence of events without consideration of the amount of time.
Trilobites form one of the earliest known groups of arthropods.
Trilobites are often placed within the arthropod subphylum Schizoramia within the superclass Arachnomorpha (equivalent to the Arachnata), although several alternative taxonomies are found in the literature.
Trilobites had many lifestyles; some moved over the sea bed as predators, scavengers, or filter feeders, and some swam, feeding on plankton.
