USA TODAY. A geologist in Canada may have discovered fossils of ancient sponges dating back 890 million years, 350 million years older than the oldest undisputed sponge fossils. The fossilized ...Sponge spicules are made of calcium carbonate or silica. Large spicules visible to the naked eye are referred to as megascleres or macroscleres, while smaller, microscopic ones are termed microscleres. The composition, size, and shape of spicules are major characters in sponge systematics and taxonomy .As this process continues, the bone becomes more and more rocklike. It's like filling a sponge with glue -- the sponge's physical structure stays the same, and the pores and pockets within it fill up. The glue makes the sponge sturdier and more resistant to damage. Large, thick bones, which have more room for mineral glue, make better fossils ...

A famous locality for fossil sponges is the Cretaceous Faringdon Sponge Gravels in Faringdon, Oxfordshire in England. 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). Hydnoceras specimens are typically around 8.375 inches long, and about 3.5 inches wide. 8 pronounced ridges run down along the length of the sponge and are crossed by horizontal ridges, producing conical swellings at intersections. Hydnoceras fossils' entire surfaces are typically covered by coarse and fine rectangular patterns of narrow ...Sponges belong to our earliest ancestors. However, fossils, molecules and genes disagree on the rise of these early animals. A large international team of researchers around Christian Hallmann and Benjamin Nettersheim from the Max Planck Institute for Biogeochemistry now found new molecular clues suggesting that sponges may have … ….
