Jan 5, 2023 · Fossil of the month: Constellaria. In the Ordovician rocks of central Kentucky, the most common fossils are branches of a type of organism called a bryozoan. Many bryozoans have similar outward appearance, which can make them difficult to identify to genus or species. This month’s fossil, however, is the easy-to-identify bryozoan, Constellaria. Jul 14, 2015 · Bryozoans are an important part of the benthic marine fauna in a wide variety of modern environments and are found in rock forming abundance in a number of settings throughout much of the Phanerozoic.

Marine bryozoans show up in the fossil record in the early part of the Ordovician Period, about 485 million years ...Since the publication of Ontogeny and Phylogeny (Gould, 1977), many workers studying fossil organisms have used heterochrony as a working hypothesis to account for phylogenetic changes in evolving lineages. Previous studies have dealt largely with solitary, aclonal organisms, but heterochrony has also been identified in clonal colonial … ….
