nov. gen. may have lived as an obligate commensal with ammonites and/or marine reptiles. Notwithstanding this, it is quite possible that it lived on hard, inorganic substrates in the littoral zone. However, further indirect support for commensal life is the absence of any other neobalanomorph plates, conspecific or otherwise, at this locality. Although negative evidence, it suggests there were no other barnacles present, compared to, for example, the variety of forms known to have lived on hard substrates along the rocky coast at Ivö Klack (
