The importance of oxygen in supporting early animal ecosystems is unclear because most proxies are unable to distinguish well-oxygenated from intermediate waters. Here, the authors show that early skeletal animals were restricted to well-oxygenated habitats, suggesting they had a high metabolic oxygen demand.
