Australiceras is an extinct ammonite genus from the upper part of the Early Cretaceous, Aptian stage, included in the family Ancyloceratidae.

Australiceras has an evolute shell, coiled with all whorls showing in keeping with its inclusion in the Ancyloceratida.

Ribs on the outer whorls become free of tubercles and end up all smooth.

Australiceras bears some resemblance to Tropaeum and Balearites, both related genera, some even considers that Australiceras is actually synonymous with Tropaeum,[3] while others denying that.
