Abstract
The mid-Tonian-aged Heavitree Formation, the basal unit of the Amadeus Basin succession, has long been believed to be devoid of metazoan fossils. Since a recent review of isolated occurrences of purported metazoan traces and remains within the formation’s upper unit, however, that conclusion has been questioned and led to the identification of new fossil remains, including imprints of Aspidella reported herein. Previously, organic-looking structures encountered in rocks older than mid-Ediacaran (ca 580 Ma) were commonly interpreted as originating inorganically, primarily through water escape, but a recently examined outcrop of the upper unit of the Heavitree Formation revealed a variety of water escape structures in association with, but structurally distinct from, a suite of organic impressions.
