Multibranched relative of starfish; lives attached to the ocean bottom; some living species "sea lilies". See all other plans. Middle School Earth Science: Cartilage fish; many living species. By correlating fossils from various parts of the world, scientists are able to give relative ages to particular strata. And, even though the rock types were different, scientists could assign relative ages to the other rocks based on their fossils.
Teaching about Earth's history is a challenge for all teachers. Earth's Spheres and Internal When one outcrop contains two index fossils from two different time periods, it acts as a 'missing link' between other outcrops that have only one of the two fossils.

Once they are able to manipulate the cards into the correct sequence, they are asked to worksueet a similar sequencing activity using fossil pictures printed on "rock layer" cards. Locally, physical characteristics of rocks can be compared and correlated.
