She said the similarities to teeth, the ancient odontodes of armored fish, and the sensilla of arthropods was striking. "We think that the earliest vertebrates, these big, armored fish, had very ...

In 2015, two members of the Blue Beach Fossil Museum in Nova Scotia found a long, curved fossil jaw, bristling with teeth.

Chance discovery of 365-million-year-old fossil reveals new species - The large fish, spanning nearly a metre on the lake bed ...

Sensory features on the armored exoskeletons of ancient fish may be the reason why humans have teeth that are sensitive to cold and other extremes.

Although dentin-lined tubules in Eriptychius resembled invertebrate sensilla, they contained dentine and had features indicating sensory capability, including open pulp cavities and large dentine ...

However, the sensitive parts inside the hard enamel first evolved for something quite different. New research from the University of Chicago shows that dentine, the inner layer of teeth that transmits ...

As for megalodon’s feeding habits, determining what it ate based on fossil evidence poses challenges, according to McCormack. “We know that they fed on large marine mammals from tooth bite ...

A new study, published on May 21 in the journal Nature, has revealed surprising information about the origins of human teeth. Our teeth evolved from the piercing “body armor” of extinct fish ...

UC Davis study of 161 fish species using high-speed video reveals evolutionary trade-off: large teeth prevent mobile jaw development.

Sensory features on the armored exoskeletons of ancient fish may be the reason why humans have teeth that are sensitive to cold and other extremes.

As for megalodon’s feeding habits, determining what it ate based on fossil evidence poses challenges, according to McCormack. “We know that they fed on large marine mammals from tooth bite ...
