Eldoradia and Acrocephalops (Trilobita: Bolaspididae) from the middle Cambrian (Miaolingian) of northern Greenland (Laurentia)

The ptychoparioid trilobites Eldoradia and Acrocephalops (Family Bolaspididae) are described from the middle Cambrian (Miaolingian Series) of northern Greenland (Laurentia). Eldoradia, originally described from the Secret Canyon Shale of Nevada, is recorded from south-western Wulff Land, North Green...

Description
Summary:The ptychoparioid trilobites Eldoradia and Acrocephalops (Family Bolaspididae) are described from the middle Cambrian (Miaolingian Series) of northern Greenland (Laurentia). Eldoradia, originally described from the Secret Canyon Shale of Nevada, is recorded from south-western Wulff Land, North Greenland, where it occurs together with Modocia and Olenoides. Eldoradia caerulioris n. sp. is established. The occurrence of Eldoradia in the lower part of the Blue Cliffs Formation indicates a minimum late middle Cambrian age (Miaolingian Series, Guzhangian Stage) for the base of the formation. Type material of Acrocephalops, a relative of Eldoradia originally proposed on the basis of material from the Miaolingian Series (Wuliuan Stage) of Inglefield Land, North-West Greenland, is redescribed.
