When did armored fishes become extinct?

Ostracoderms (shell-skinned) are any of several groups of extinct, primitive, jawless fishes that were covered in an armour of bony plates. They appeared in the Cambrian, about 510 million years ago, and became extinct towards the end of the Devonian, about 377 million years ago.

When did placoderm fish go extinct?

Placoderms dominated aquatic environments for 70 million years until they suddenly went extinct some 360 million years ago, paving the way for modern bony fish (osteichthyans) and sharks and rays (chondrichthyans).

What is the name of the armored fish which lived 360 to 380 million years ago?

Titanichthys
Summary: Scientists have shown that the Titanichthys — a giant armored fish that lived in the seas and oceans of the late Devonian period 380-million-years ago — fed in a similar manner to modern day basking sharks.

What happened armored fish?

During the Devonian, placoderms went on to inhabit and dominate almost all known aquatic ecosystems, both freshwater and saltwater. But this diversity ultimately suffered many casualties during the extinction event at the Frasnian–Famennian boundary, the Late Devonian extinctions.

Are there any living Placoderms?

placoderm, any member of an extinct group (Placodermi) of primitive jawed fishes known only from fossil remains. Placoderms existed throughout the Devonian Period (about 416 million to 359 million years ago), but only two species persisted into the succeeding Carboniferous Period.

Why did armored fish go extinct?

It was thought for a time that placoderms became extinct due to competition from the first bony fish and early sharks, given a combination of the supposed inherent superiority of bony fish and the presumed sluggishness of placoderms.

How strong is a Dunkleosteus bite?

A well-known denizen of museum displays, Dunkleosteus terrelli could have exerted up to 1,200 pounds of force with its bite, the investigators estimate. When applied along its jagged snapping-turtle-like jaws, such a force would translate to about 8,000 pounds of pressure per square inch, the researchers find.

Is there a market for armored catfish?

People have been harvesting armored catfish in Florida and Texas for years, but to date, there is no market for the fish. Although harvest can have benefits, the most important control is to prevent aquarists and fishers from releasing aquarium or wild-caught fish.
