Palaeoscolecid sclerites from the Upper Cambrian Mila Formation of the Shahmirzad section, Alborz Mountains, northern Iran
Phosphatic, discoidal sclerites with prominent nodes on the external surface have been found in Upper Cambrian inter-reef calcareous grainstone of the Mila Formation in the Shahmirzad section, Alborz Mountains, northern Iran. This is the first record of a palaeoscolecid worms from Iran. Isolated scl...
