Which New York State index fossil may have been present in a rock layer that is missing due to the unconformity?
The trilobite is the index fossil
What is the relative age of a fossil that can be determined by comparing it to an index fossil is called?
becaues it is that they been around so long
Would horseshoe crabs be useful as an index fossils?
No, Index fossils are used to date certain rock layers where the fossil is found. So it's usefull when you can find a certain index fossil only in a small period of time. So you can get the most precise dating for the rock layer. Horseshoe crabs are known as a 'living fossil', the first fossils of horse shoe crabs are found 450 millions years ago. So when you find a fossil of a horse shoe crab in a rock or sediment, you can't say anything about the age of the rock.
Would horseshoe crabs be useful as index fossils?
No because they have been alive for a very long time
What does the term living fossil mean?
A living fossil generally refers to a living organism, animal or plant, whose species has been around long enough on the planet to be part of the fossil record. Most fossilized species are extinct, but there are a few which are either still in existence, or have descendents which closely resemble them.

What makes a fossil an index fossil?
fossils are preserved animals or plants. but index fossils are fossils have wide distribution,many of them,evolves rapidly, and very easy to recognize. Ammonites are index fossils. The fossils were made only in a certain short time period.
What is living fossil mean?
To become a fossil, something must have died a very long time ago, as the process of fossilization takes eons. When people talk about a "living fossil" they are talking about a species which has been around unchanged long enough for members of that species to become fossils, like a coelacanth. Or more jocularly, you might be making fun of someone because of their age. ("Mr. Overthwaite, the math teacher? He's been teaching here forever. He's a living fossil!")
