Science Homework 9/21 Fossil Classification

I think that this would be classified as a Original Remains fossil. I think this because that is typically the kind of fossil shells become. Also, usually what happens with this type of fossil is that circulating ground water (with shells this would mean ocean water) removes the original organic material of the shell, completely replacing it with mineral, resulting in an exact copy of the shells.


I think that this fossil would be classified as a Original Remains fossil. I think this because the insect was encased by the resin while it oozed down the tree and preserved when the resin hardened into amber.

Science Homework 9/17

I Think that the order of the strata, from newest to oldest is 3, 1, 6, 5, 4, 2. I know that layer 4 is older than layer 6 because of the principal of superposition. I know that layer 3 is the newest because of cross-cutting relationships, 3 being the intrusion. I think that 2 is the oldest because even though it goes up past some other layers, it does not come all the way to the surface, and it originates at the very bottom. I also know that layer 1 is newer than layer 5 because of the principal of superposition.
