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.
