Reporters from the Chinese Academy of Sciences Nanjing Institute of Geology and Paleontology was informed that by the Chinese and German paleontologists composed of research team, recently found in Anhui, China, a batch of 440 million years ago flower bone sponge fossils: Chinese ancient flower bone sponge. This is the oldest flower bone sponge ever found, pushing the history of similar sponge fossils forward by more than 300 million years.
Floral bone sponge is a more common type of six-shot sponge in the present sponge. They have a variety of appearances and a wide range of water depths, up to a maximum of 6,700 meters or more.
This time, the team found the 440 million-year-old fossils of flower-bone sponges in sponge swarms in Luxian County, Anhui Province. These flower sponges are spherical or spheroidal, with thick walls and water holes on the surface. Given that its characteristics are different from other known flower bone sponges, the team named it the Chinese ancient flower bone sponge.
“The discovery of ancient flower bone sponges in China is of great significance to the exploration of the origin and evolution of sponge animals. It tells us that as early as 400 million years ago, these common six-shot sponges appeared on Earth. Dr. Li Lixia of the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, who participated in the study, said.
The results have been published in the German journal Paleontology, published in a recent journal.
