The Harlech Dome in North Wales consists of a thick sequence of largely deep-water sediments in which fossils are hard to find, and similar rocks are also found in the tectonically deformed Caernarvonshire Slate Belt.
Volume1 LATE MIDDLE CAMBRIAN TRILOBITES FROM TRIAL RIDGE, SOUTHWESTERN TASMANIA by J.B. Jago &A.V. Brown. Wainwright's hand-drawn walking guides are perhaps the most distinctive and unusual such guides ever devised.
This guide, first published incontains Wainwright's original instructions and route maps for 34 walks in 'a land of suprises' – the interesting limestone country in the Whernside, Ingleborough and Penyghent areas of Yorkshire. Holocene prograded coastal sequences at Becher/Rockingham, southern Western Australia, contain a detailed record of sea level over the last yr.
Radiocarbon dating and use of a distinct stratigraphic indicator as a sea-level marker permit reconstruction of sea-level history and suggest that the sea was at least m above present datum about yr B.P. before falling Cited by: Return to the Paleontologoy Archives.

LOWER CAMBRIAN TRILOBITES OF THE LATHAM SHALE The Latham Shale in San Bernardino County, California, offers the amateur collector a wide range of Lower Cambrian trilobites. According to a few marine paleontologists, this area, which includes the Marble and. The rocks at Ben Suardal consist of the Durness Group (previously Durness Limestone) and are late Cambrian/ early Ordovician in age, being about million years old.
The Dunrness Group forms a narrow, discontinuous belt, extending along the North-western side of Scotland from the Durness-Eriboll area, through Assynt and Kishorn, to Skye.
Infrequent Cambrian fossils can be observed on the surfaces of dolomitic limestone boulders at the base of Ben Suardal. They are not particularly easy to find and are hard to collect, but their great age should be an incentive to at least try to find.
