What paleontological feature, growing incrementally, is analyzed to map out vast seasonal movements across Siberia and Alaska?
Answer
Tusks
Scientists utilize the tusks of woolly mammoths, which exhibit incremental growth patterns similar to the rings found in trees, as a primary tool for reconstructing ancient movement patterns. By analyzing the detailed chemistry within these ivory layers, researchers can determine specific temporal and spatial information, such as when an animal was near a particular water source or moving through different geological provinces. This analysis effectively transforms the static concept of a location into a dynamic travel log, allowing scientists to map out vast seasonal migrations that could cover hundreds of miles.
