Question

part 4: geologic deposits of new york state
the map below shows the ages of the bedrock found across new york state. using this map, determine if you would or wouldnt be able to find the fossil from layer b in new york.
write 3-5 sentences explaining why you would or would not be able to find this fossil in new york, and if you would be able to, where would you expect the fossil to be?

Explanation:

First, we identify that Layer B corresponds to the Mesozoic (Cretaceous, Jurassic, Triassic) based on the map's legend. The map shows a small area of Mesozoic bedrock (the green region) in the southeastern part of New York State, specifically the Coastal Plain (Atlantic Embayed Section). Fossils from Layer B would only be present in bedrock of the same geologic age, so they can only be found where this Mesozoic bedrock exists.

Answer:

You would be able to find the fossil from Layer B in New York State. It would be located in the southeastern corner of the state, in the Coastal Plain (Atlantic Embayed Section), which is the only area on the map with Mesozoic bedrock (the green-colored region matching Layer B's geologic age). This is because fossils are only preserved in bedrock from the same time period as the organism's existence, so the fossil can only exist where the corresponding age bedrock is present.
