Chondrites isp.


Description: Chondrites is a branching, vertically to horizontally oriented feeding burrow; the three-dimensional character of Chondrites can be visualized by imagining an upside-down tree, with a main burrow "trunk" connecting to the sediment-water interface and increasingly complex branches downward into the sediment. Chondrites is interpreted as a feeding burrow that is often associated with low-oxygen substrates, although there are exceptions to this generality.
