A new temporary section across the Ludlovian‐Downtonian boundary (Upper Silurian) at Siefton (Nr Craven Arms), Salop, England, is described. The sediments present in the section were deposited in both intertidal and subtidal marine environments. The shelly faunas across the section are recorded and considered to be transported assemblages. Both burrowing and boring trace fossils occur in the presumed subtidal environments. Evidence for a late Whitcliffian marine transgression, following a marine regression is presented.
