Morphology and stratigraphic range of the phyllocarid crustacean Caryocaris from Alaska and the Great Basin
£1.00
Exceptionally well-preserved specimens of Caryocaris from Alaska and the Great Basin show a peculiar shell enrolment; several other important skeletal details are described for the first time. In the light of this new material, Ruedemann's types that are the basis for his reconstructions of Caryocaris are re-examined. Finally, a review of the stratigraphic range of Caryocaris leads to the conclusion that none of its reported Silurian species are definitely Caryocaris. The range of the genus should therefore be restricted for the present to the Ordovician and probably to the lower half of the system.
