| Abstract: | Stromatoporoids are an important group of fossil sponges that form some of the largest reef complexes in the fossil record and are valuable in palaeoecological and facies analysis. They are frequently large and easily studies in the field and in hand specimen. Using their growth forms it is possible to determine some features of sediment deposition rates and changes in their growth direction during life show episodes of turbulence that affected the sea bed. This article intriduces them, and gives practical help to interpret thier growth forms in quaries and cliffs where you may see them on fieldwork. You will realized just how absorbing these fossil sponges can be. |
