Growth and environmental hazards of the upper jurassic colonial coralactinastrea matheyi (koby) from Portugal

Development and growth of Upper Jurassic colonial corals(Actinastrea matheyi) from Portugal was ruled by abiotic factors (water energy, sedimentation rate) and biotic factors (predation and parasitism). Phases of growth were interrupted by high energy events which caused tilting of the corals. In addition, intensified parasitism and predation occurred
