Fossil sponge.

The Sponge Character in the Fossil Record. Sponges are one of the first animal groups to diverge from the metazoan lineage; however, their time of origin is not resolved, partly because of the lack of undisputed fossils at the time that molecular clocks estimate their origin (Wörheide et al. Reference Wörheide, Dohrmann, Erpenbeck, …Feb 8, 2022 · When they surveyed the Arctic sponge grounds, the researchers also discovered tiny shrimp, small worms and pudgy sea stars.

The fossils include sponges, priapulid worms and arthropods, and shed new light on how living things colonised the deep oceans.There are many types of corals or animals that look like corals – like bryozoans (moss-animals) and stromatoporoids (sponges). These animals often live in colonies but sometimes are solitary animals. Michgan has many fossils of sea sponges, horn corals, branching corals, and of course Petosky Stones which are fossil coral. Sea LiliesIn the fossil record, these groups are often represented by the spicules alone, which may be preserved in great abundance, or by masses of fossilized sponges associated with reefs. Phylum Porifera (Cambrian-Recent) (see video, approximately 10 minutes, on biology of sponges) Demospongiae represents the dominant class of living sponges, representing more than 90% of all those alive today. Few demosponges have hard skeletons, leaving behind a sparse fossil record compared to other classes. The clade is, however, very diverse, with over 7000 living species. Many demosponges support other organisms (including sea ...A taxonomic genus within the order Lithistida – Cretaceous fossil sponges; Synonym of † Schrammeniella. Usage notes .
