The distribution of trilobite fossils from various periods in the fossil record are shown in the map here. Fossil species on both side of the red line differ for the Cambrian and Ordovician periods. Which statements are supported by the evidence shown in the map? Select ALL that apply.

A) Trilobites from different periods fossilized, but ocean currents moved them to new locations.
`
B) Trilobites from different periods fossilized, and plate tectonic movement relocated those fossils.

C) Trilobites from different periods fossilized at different times but were once separated by an ocean.

D) Trilobites from different periods fossilized on land which was later flooded during the Ordovician period.

E) Pangaea formed more recently than the trilobite fossil formation, bringing the fossils together from different regions of the world.
