The placoderms were a diverse group of ancient armoured fishes and it's widely believed that they are ancestral to virtually all vertebrates alive today, including humans. Placoderms dominated aquatic ...

Our study supports the hypothesis on the right, where placoderms are instead a distinct side branch. Benedict King and Brian Choo, Flinders University The iconic placoderm Dunkleosteus.

Ancient armoured fish had complex musculature — including abdominal muscles — the discovery of uniquely preserved tissue on Australian placoderm fossils has revealed.

Alienacanthus is a member of an extinct group of fish called placoderms, which are some of the first jawed vertebrates. They are armoured fish of various shapes and sizes and are essential to ...

You might take it for granted now, but your jaw is the result of an evolutionary journey lasting over 400 million years. Life reconstruction of Qilinyu, a 423-million-year-old fish from the Kuanti ...

Placoderms had thick bony plates enveloping the head and trunk regions. They ruled the seas, rivers and lakes of the world for 70 million years, becoming extinct around 360 million years ago.

Placoderms have often been reconstructed based on comparisons with sharks. But the two may have behaved more differently than previously thought. Mr. Engelman said: "Mouth size is probably the biggest ...

This was generally how fish were built in that time; placoderms were the dominant type of fish for 100 million years. Out of them, Dunkleosteus was probably the most fearsome.

We are all derived from placoderms Placoderms were really gnarly armoured fishes that ruled the oceans, rivers and lakes of the world from about 440-360 million years ago.

Covered with thick, bony plates covering the head and trunk, placoderms ruled the world's oceans, rivers and lakes for around 70 million years. They were then were wiped out around 360 million years ...

Unlike in other placoderms, the upper jaws of Alienacanthus were capable of a slight movement independently of the skull, helping to accommodate the lower jaw. Most extreme case The extended lower jaw ...
