Fossil Pictures Homework Due 9/24

Jaclyn Salevsky WhiteB3


<----
I would classify this fossil as molds and casts. I say this because if it looks like the fossil dissolves out of the rock, and then it made a hollow depression in the rock, which is a mold. A mold shows it's original shape which you see in the picture. Cast which is also part of the fossil is the copy or original fossil.


I would classify this fossil as the original remains. I say this because this insect is preserved entirely. This fossil also looks like it has been trapped in resin. Resin comes for a tree, a type of sap comes out and gets the insects caught inside. ---->
