AI Summary

A previously overlooked fossil from a museum has contributed to a revised understanding of animal evolution. This discovery is significant because it helps to address a long-standing gap in the fossil record, known as the "Furongian gap." This period, spanning from approximately 497 million to 485 million years ago, had previously been characterized by a scarcity of fossils. The new research, published in BMC Biology, sheds light on this previously understudied era, providing a more comprehensive picture of animal evolution during this time.
