... to the complex, including forms that correspond to Rottnestia amphicavata , were all identical and conform to those of Gonyaulax elongata from the Orkney Islands. The molecular analyses thus support the conclusion that the morphological variability is not reflected genetically and occurs within one species...

Some extinct taxa are also discussed when their morphology is close to that of recent species (e.g. Spiniferites lenzii , S. twistringiensis and S. pseudofurcatus ), as well as some species possibly related to the motile Gonyaulax spinifera complex. The ISAs of S. mirabilis and S. hyperacanthus...
