Calcispongiae, Seeds and a plant of the Carboniferous
The limestones overlying the Nematophytes bearing dolomites contain Calcispongiae (FIGURE 9) that very much compare with Girtyocoella and/or Amblysiphonella of the Carboniferous.
Thanks to the discovery within its carbonate facies of certain Calcispongiae, seeds and a plant we could assigne the upper part of the San Luis Cover to the Carboniferous: thus, after more than 80 years Keller and Wellings (1922) were rightly vindicated.
