I believe it is called a nautilaus Ammonites are extinct. Nautilus are still alive. Both are cephalopods with coiled, partitioned shells.
Marine fossils include a variety of organisms that lived in ocean environments, such as ammonites, which are extinct marine cephalopods with coiled shells; trilobites, a group of extinct arthropods; and brachiopods, which are bivalve-like organisms with hard shells. Other examples are corals, which can form extensive reef structures, and echinoderms like sea urchins and starfish. Additionally, fossilized remains of marine mammals, such as whales and dolphins, can also be found in the geological record.
Some examples of extinct marine mammals include the Stellar's sea cow, the Caribbean monk seal, and the Japanese sea lion. These species were primarily impacted by overhunting, habitat loss, and changes in the marine environment due to human activities.
Limestone is formed on the floor of ancient seas from the skeletal remains of marine organisms such as coral, forams and molluscs, etc.
No, marine otters are not extinct. While they have faced threats from hunting and habitat loss, populations of marine otters still exist in various regions, particularly along the coastlines of the Pacific Ocean. Efforts are being made to protect and conserve these otters to prevent extinction.
A cuttlefish is not a fish at all but a marine invertebrate. Cuttlefish are molluscs in the class cephalopoda along with octopi and squid. Molluscs also include bivalves (clams, oysters and mussels) and gastropods (snails and slugs).
Trilobites, and eurypterids (giant marine scorpions). Ammonites are not arthropods but molluscs.

Chiton's are marine molluscs in the Polyplacophora class. They used to be known as Amphineura.
An ark shell is a member of the family Arcidae of saltwater clams or marine bivalve molluscs.
Nudibranchs are members of the group of molluscs known as gastropods, specifically within the subclass Opisthobranchia. These marine snails are characterized by their lack of a shell and their vibrant colors and patterns.
An extinct marine invertebrate animal.
Some examples of extinct marine mammals include the Stellar's sea cow, the Caribbean monk seal, and the Japanese sea lion. These species were primarily impacted by overhunting, habitat loss, and changes in the marine environment due to human activities.
Marine life dies and goes extinct. That's what happens when where they live gets destroyed.
