文摘

Exceptionally-preserved fossils are extremely rare in the late Cambrian. New intervals with soft-tissue preservation identified in the McKay Group. New aglaspidid with 12 trunk segments supports vicissicaudatan affinities. Exquisite details of trilobite gut and first Furongian ctenophore are described. First report of Burgess Shale-type preservation in the late Cambrian of Laurentia.
