permian

Question

What fossils were in the permian era (including ammonoids)?

Answer 1

• Ammonoids: Cephalopods with complex shells were common in the Panthalassa ocean, particularly specialized types like Araxoceratidae.
• Brachiopods: Extremely abundant, such as Neospirifer, which was dominant in seafloor environments.
• Fusulinids: Large, complex foraminifera that acted as significant rock-forming organisms.
• Crinoids: "Sea lilies" that formed dense, forest-like beds on the seafloor.
• Vertebrates: Synapsids (mammal-like reptiles) like Dimetrodon appeared in this era.
• Other: Bryozoans, horn corals, gastropods, and rare, declining trilobites.
