Fossils, Morphology and Molecules A Cushman Symposium in Memory of Alfred Loeblich and Hellen Tappan Chaired by Jere Lipps and Susan T. Goldstein This symposium brings together experts to discuss the latest in systematic and evolutionary research on various protists, especially foraminifera. Development plays an important part in shaping adult morphology and morphological disparity, yet its influence on evolutionary processes is seldom explored because of a lack of preservation of ontogenetic stages in the fossil record. The samples were then washed repeatedly in water and passed through a 63 µm screen. 5). Chamber arrangement and aperture style, with many subtle variations around a few basic themes. Environmental conditions such as temperature and trace elements may play an important role in stimulating such unusual test occurrences. However, due to the inadequate preservation of early unilocular (single-chambered) foraminiferal tests and difficulties in their identification, the evolution of early foraminifers is poorly understood. The unusual morphology of these foraminifera, “improbable” and rare, is mysterious clues to the natural survival of such organisms. RIGAUD ET AL.—THE FORAMINIFERA INVOLUTINA REVISITED 237 Structure and morphology of Involutina In Involutina, the test architecture is unvarying.

(2013) proposed a new classification of Foraminifera based on morphology and molecular analysis in tandem. There are reasons to suspect that selective predation may play a role in shaping foraminiferal morphology. Foraminifera are commonly defined as marine testate protists, and their diversity is mainly assessed on the basis of the morphology of their agglutinated or mineralized tests. endstream endobj 464 0 obj <>stream Introduction History Morphology Wall Structure and Composition Chamber Development, Architecture and Shape Palaeo-ecology and Its Significance Geological Distribution Uses of Foraminifera Conclusion Reference 2 Foraminifera: Fossil Record.
