✦ Synopsis


A group of alternating shale and limestone beds in the Dibunophyllwn Zone of the Carboniferous Limestone at a quarry near Carnforth, Lancashire, shows an interesting variety of well-preserved tracefossils. These include exceptionally large tracks of Helminthopsis type, burrows of a tubular character which give rise to the characteristic "Stick Bed" structures, "cauda-galli" markings and piles of worm castings. The new ichnogenus Chomatichnus is proposed for the last of these. PLATE 3 A "Weals", Helminthopsis-type tracks, base of Bed 2, Wegkr quarry. B Upper surface of Bed 6, Wegkr quarry. C Chomatichnw.
