Ichnostratigraphy of the Ediacaran-Cambrian boundary: new insights on lower Cambrian biozonations from the Soltanieh Formation of northern Iran

, 2017
Strata in the Central Alborz Mountains, northern Iran, are interpreted to show continuous sedimentation from Ediacaran through Cambrian times. The Soltanieh Formation consists of five members: Lower Dolomite, Lower Shale, Middle Dolomite, Upper Shale and

Resolving the position of problematic lower to middle Cambrian Lophotrochozoa: a critical appraisal of tommotiid and stem-brachiopod character homologies

, 2012
The origin and early evolution of Brachiopoda can be traced back to the plethora of scleritomes and brachiopod-like taxa in the lower Cambrian. Most conspicuous are members of Lagerstätten such as the Burgess Shale and Chengjiang faunas.
