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 ...

In 2024, researchers announced several new findings collected from certain Cambrian trilobite fossils from Morocco. These fossils stood apart from others of their kind because of their condition ...

Three of its weapons are visible in the fossil shown here: claws, propulsive swimming flaps, and at the base of the claws, eyes on eyestalks. The emergence of vision in the Cambrian helped both ...

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 ...

It has long been suspected that the sparseness of the pre-Cambrian fossil record reflects these two problems. First, organisms may not have sequestered and secreted much in the way of fossilizable ...

The growth and lifespan of Parvancorina minchami, small anchor-shaped animals that lived on the seafloor about 550 million ...

Animals living about 500 million years ago spent time on mudflats that were periodically exposed to the air. The finding suggests that some of the earliest animals were able to survive outside of ...

Now, with access to uniquely well-preserved Cambrian fossils, Dr Greg Edgecombe and Dr Xiaoya Ma are seeing the evolution of vision through the world's oldest eyes. To understand the eyes of ancient ...

The fossils found date back to a geological and evolutionary period known as the Ediacaran–Cambrian transition. This was when the Ediacaran Period, which spanned 94 million years from the end of the ...

A major fossil site bearing witness to the Cambrian explosion and providing evolutionary evidence for early life-forms, it ...

“If their interpretation that yunnanozoans are vertebrates are correct, that pushes the origins of vertebrates into the early Cambrian,” he says, as yunnanozoan fossils predate the time vertebrates ...
