The trace fossilBichorditesappears as an intrastratal burrow and occurs in shallow-marine deposits. Its modern counterpart is the burrow produced by the spatangoid echinoidEchinocardium cordatum, found in shallow-marine regions.The relationship between burrow size and tracemaker population density was studied in the modern, subtidal, sandy deposits of a ria coast in the northeastern Japan. Burrow size decreases with increasing population density in the modern counterpart, suggesting that trace fossil size inBichorditescan be used as a proxy to quantify tracemaker population density at the time of trace formation. However, the factors that control burrow size are unclear and warrant further investigation.
