Coral fossil.

When our fossil coral was living, it must have been similar to modern corals, its colonies growing on the surface of the sea floor. The tubes in the fossil skeleton would have been filled with living polyps, feeding themselves with soft tentacles. So how did the fossil coral in our specimen become embedded in solid rock?Os professores Rodrigo e Taissa participaram de um artigo recém publicado, que descreveu fósseis de corais Scleractinia de rochas do Cretáceo da ilha James ...The Devonian coral reef diorama, based on a coral reef found north of Coralville and on other fossil remains and rock formations from Coralville and Iowa City, depicts the state when it was beneath water 380 million years ago.

Halysites is also known as the chain coral from the manner of growth observed in fossilized specimens; the genus is.Corals. Corals are cnidarians that live as polyps attached to the sea floor. Polyps of modern stony (scleractinian) corals produce a hard skeleton that is easily fossilized. Extinct rugose and tabulate corals also had hard skeletons and are commonly found as fossils. The scleractinian corals are probably descendants of the rugose corals.

However, skeletal microstructure (documented by Stolarski, 2003 in fossils) has yet to be investigated in living corals in anything like the detail needed to underpin a taxonomic hierarchy, and indeed microstructure was not fundamental to the (primarily fossil) compendiums of Vaughan and Wells (1943), Wells (1956) or Chevalier and Beauvais ...

All are fossils except, technically, the T. rex tooth, which is actually a cast of a real tooth. The rugose corals (also known as solitary or horn corals) are very often mistaken for dinosaur teeth but are older than the oldest dinosaurs, having gone extinct around 250 million years ago (the oldest known dinosaurs are around 230 million years old).
