image: The Paris Biota illustrates the oldest occurrence of derived characters in several clades and it shows that at least some Early Triassic marine communities include ancient lineages in the lowest trophic levels together with newly-evolved groups occupying higher trophic levels. This material relates to a paper that appeared in the Feb. 15 2017, issue of Science Advances, published by AAAS. The paper, by A. Brayard at Université Bourgogne Franche-Comté in Dijon, France, and colleagues was titled, "Unexpected Early Triassic marine ecosystem and the rise of the Modern evolutionary fauna." view more
