Tubiphytes-calcimicrobe rudstone, dominated by Tubiphytes spp. and associated with large echinoderm ossicles. Poorly preserved calcimicrobes, reworked mud grains, micritized clasts and coated or aggregate grains are abundant. Other bioclasts are
Soleporacean, red algae, microproblematica and the sponge Uvanella sp. Serpulids and bryozoan debris are rare. Microbial crusts were observed on a recrystallized framebuilder.
