A new study shows that the body size of the iconic gigantic or megatooth shark, about 15 meters (50 feet) in length, is indeed anomalously large compared to body sizes of its ...

Ice Discharge in the North Pacific Set Off Series of Climate Events During Last Ice Age

Repeated catastrophic ice discharges from western North America into the North Pacific contributed to, and perhaps triggered, hemispheric-scale changes in the Earth's climate during the last ice ...

Ice Age Manatees May Have Called Texas Home

Manatees don't live year-round in Texas, but these gentle sea cows are known to occasionally visit, swimming in for a 'summer vacation' and returning to warmer waters for the winter. ...

Researchers have detected DNA from ambrosia beetles that were trapped in recent tree resin for less than seven ...

New Study Reveals How Reptiles Divided Up the Spoils in Ancient Seas

While dinosaurs ruled the land in the Mesozoic, the oceans were filled by predators such as crocodiles and giant lizards, but also entirely extinct groups such as ichthyosaurs and plesiosaurs. Now ...

A new study provides substantial evidence that the first fossil feather ever to be discovered does belong to the iconic bird-like dinosaur, Archaeopteryx. This debunks a recent theory that the fossil ...
