The fossils indicate that the landmasses were once farther apart and that the organisms traveled long distances between them.

The fossils indicate that the landmasses were once joined together and then became separated over a long period of time.

The fossils indicate that the organisms swam from one landmass to the other landmass before they became fossilized.

The fossils indicate that the organisms developed independently on both landmasses and maintained their similarity as the landmasses moved apart over time.

Mucrospirifer fossils are the youngest index fossils.

Pecten index fossils are older than Paradoxides index fossils

Perisphinctes and Nerinea index fossils are about the same age.

Both index fossils were formed in the Mesozoic era.

The Cenozoic era happened before the Paleozoic era.
