Bicellum brasieri is a fossil holozoan.[1] It is one billion years old and could be the oldest example of complex multicellularity in the evolutionary lineage leading to the animals,[2][3] and has been described as bridging "the gap between the very first living creatures — single-celled organisms — and more complex multicellular life."[4] It was discovered in 2021, and is posthumously named after the late Martin Brasier, a paleontologist who was a co-author of the paper that first described it.[5]
