摘要:

Traces interpreted asSkolithossp. in aGlossifungitesichnofacies occur in the upper part of the Beans Gap Claystone paleosol, in association with a Late Ordovician marine erosional surface. Paleosol color and whole‐rock chemistry are distinctly different in the vicinity of burrows, which are enveloped by olive gray mottles, 1 to 10 cm in diameter, in which total iron (measured as Fe2O3) is 30% lower than in grayish red, “unaltered”; claystone.
