Published Earth's oldest stromatolites and the search for life on Mars
(via sciencedaily.com) The earliest morphological traces of life on Earth are often highly controversial, both because non-biological processes can produce relatively similar structures and because such fossils have often been subjected to advanced alteration and metamorphism. Stromatolites, layered organo-sedimentary structures reflecting complex interplays between microbial communities and their environment, have long been considered key macrofossils for life detection in ancient sedimentary rocks; however, the biological origin of ancient stromatolites has frequently been criticized.
Published A stone age child buried with bird feathers, plant fibers and fur
(via sciencedaily.com) Archaeological researchers have identified human remains as a child, who may have been laid on a bed of down in a Stone Age burial site discovered in Eastern Finland. There may also have been a canid at the child's feet. It reveals interesting details of how Stone Age humans buried their dead about 8000 years ago.
Published 500 million year-old fossils reveal answer to evolutionary riddle
(via sciencedaily.com) Original source An exceptionally well-preserved collection of fossils discovered in eastern Yunnan Province, China, has enabled scientists to solve a centuries-old riddle in the evolution of life on earth, revealing what the first animals to make skeletons looked like.
