| 説明 | Bryozoan - naturally intact colony attributed to Fistulipora neglecta Rominger, 1866, weathered out from Silurian rocks near Waldron, Indiana, USA (UC 15011, University of Chicago, Chicago, Illinois, USA).Bryozoans are colonial lophophorates, most of which make a calcareous skeleton. Many bryozoan skeletons have complex shapes that cannot be fully appreciated from the fossil record. Bryozoans are abundant fossils, especially in Paleozoic and Mesozoic limestones, but their skeletons usually get busted up during the storm events resulting in their final burial. |
