An older sponge is the Cambrian Vauxia. Fossil sponges differ in size from one centimeter (0.4 inches) to more than one meter (3.3 feet).Invertebrates are animals without backbones. Thus fossils in this category are those from organisms lacking backbones, such as clams, sponges, and corals. Within either area some fossils may be so small that their study is commonly termed micropaleontology, and the fossils ‘microfossils’. Paleobotany focuses on plant fossils.
