Bicellum brasieri
Bicellum brasieri is a fossil holozoan. It is about 1 billion years old and could be the oldest example of complex multicellularity in the evolutionary lineage leading to the animals. It was discovered in 2021, and is named posthumously after the late palaeontologist Martin Brasier, who was a co-author of the paper that first described it.
