WebJan 1, 2007 · Some infillings contain fragments of Myopholas or Girardotia, bivalves that rotate during penetration of soft to firm substrates. These burrows were probably initiated above the unconformity surface and extended down into an already perforated and softened mudstone surface. A few burrows may be due to a burrowing coelenterate. WebThe Jurassic anomalodesmatan Myopholas may be ancestral to the rock-boring pholads. The shell morphology of the more significant genera of the Anomalodesmata is reviewed from rare well preserved specimens of various ages from collections in North American, European, and Australian institutions.
