The article mention mudstone, so it was mud once but is now a lot less muddy and has dried out.

Courtesy wikipeadia; Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Grain size is up to 0.063 millimetres (0.0025 in) with individual grains too small to be distinguished without a microscope.
