Final answer:
William Smith was the mine surveyor in England who helped relate fossil packages to the age of rock layers by matching fossils to create maps and predict the types of rocks and fossils found in different locations.
Step-by-step explanation:
The mine surveyor in England who helped piece together how fossil packages relate to the age of rock layers was William Smith. In the early 19th century, Smith noticed that fossils changed according to location while digging canals. He matched fossils to create maps, which allowed him to predict the types of rocks and fossils found in different locations, aiding in understanding the age of rock layers.
