Sea otters’ tool use leaves behind distinctive archaeological evidence
Researchers used an interdisciplinary approach combining ecology and archaeological methods to study sea otters’ past behavior
March 14, 2019
An international team of researchers has analyzed the use by sea otters of large, shoreline rocks as “anvils” to break open shells, as well as the resulting shell middens. The researchers used ecological and archaeological approaches to identify patterns that are characteristic of sea otter use of such locations. By looking at evidence of past anvil stone use, scientists could better understand sea otter habitat use.
Sea otters are an especially captivating marine mammal…
