Thalassinoides

burrows are found in the Yeoman. The larger burrows are Thalassinoides-like structures that are thought to have been re-burrowed, as indicated by the smaller included burrows (i.e. Planolites, Chondrites) (Kendall 1976, 1977; Haidl et al., 1997; Canter, 1998; Pak et al., 2001). Several types of dolomitization are present in the Yeoman Formation.
