“Ecdysozoans were prevalent in the Cambrian fossil record and we know they didn’t just appear out of nowhere. But, until now, we had no concrete fossil evidence to confirm it.” This ...

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 ...

These fossils, dated to approximately 535 million years ago, were found in the early Cambrian Kuanchuanpu biota in southern Shaanxi Province, China. The research, led by Professor Zhang Huaqiao ...

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 ...

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 ...

it's when most of the major animal groups appear in the fossil record. The Ediacaran species largely disappear when the Cambrian explosion happens. As such, they straddle an ancient age when the ...

We study the anatomy and genetic structure of fossils to understand the evolution of organisms. Members of Jakob Vinther’s research group study a broad range of subjects. One focus of our research is ...

Lead researcher Ian Hughes, a Ph.D. candidate from Harvard's Department of Organismic and Evolutionary Biology, expressed the excitement surrounding the find, noting, "Ecdysozoans were prevalent in ...
