In addition, at least one species could not be ascribed to a genus. All species in the material are described in open nomenclature, partially due to the imperfect preservation,partially due to the outdated systematics to the scarcity of recent revisions. The dominant group in the material are nepiomorph bivalves, which constitute around 60% of the specimens in the studied material. A high proportion of nepiomorphs in the fauna from Amerboh Group is...
