Early Cambrian fossils reveal how a small, shelled animal evolved to deal with attacks from a predator. The finds confirm a popular hypothesis, until now lacking in clear evidence, about what ...

For over half a billion years, evolution has sculpted the nervous systems of bilaterian animals, equipping them with remarkable capabilities to process information, coordinate movements, and respond ...

The findings suggest that significant changes in geochemistry occurred before the first appearance of many Cambrian fossils, indicating a complex interplay between biological evolution and ...

Photograph by James L. Amos The iconic arthropods of the Cambrian were the trilobites, which left a huge number of fossils. Trilobites had flattened, segmented, plated bodies that helped to ...

María Herranz (Rey Juan Carlos University), analyzed exceptionally well-preserved fossils from key Cambrian deposits. These fossils include representatives of the early-evolving Scalidophora ...

A study led by researchers at the American Museum of Natural History presents the oldest known example in the fossil record of ... evolutionary arms race in the Cambrian. "Predator-prey ...

However, a close look at Cambrian-age (541 million years to 485 million years ago) fossils of Scalidophora, a subgroup of Ecdysozoa found in marine environments, has revealed the source of these ...

Among the many fossilized stars is a 26-meter-long Mamenchisaurus jingyanensis, a gigantic herbivore that lived around 150 million years ago and had one of the longest necks of its species. It is ...
