Scientists Stunned to Unearth 500-Million-Yr-Old 3D Cambrian Trilobites Fossils in Best Preserved Condition in Volcanic Ash ...

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 ...

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 ...

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 ...

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 ...

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 ...

first appeared in the early Cambrian. They represent a crucial lineage for investigating the evolutionary trajectory of the ventral nerve cord in ecdysozoans. By studying fossils from the ...

“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 ...
