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 ...

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 ...

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 ...

Others in the paleontological community took the fossils as evidence of a more slow and steady animal evolution than the Cambrian explosion model would suggest.Now, Bengtson says, Matz has found an ...

“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 ...
