Such an assemblage is interpreted as representing the restrictive conditions of
an intertidal flat environment. Analysis of the sedimentary facies shows that the
fossils come from a sequence of interbedded shales, siltstones and sandstones ...

The different interpretations of the faunal assemblages from the two areas accord
well with the different interpretations of the containing sedimentary facies. The
shales at the top of the Weltevrede Formation at Howison's Poort are thought to ...
