An article published in the journal “Botanical Journal of the Linnean Society” describes a research on a fossil of Tortotubus protuberans, a kind of primordial fungus identified as the most ancient organisms that lived on the mainland so far discovered. The fossil dates back about 440 million years ago and it’s an organism that was crucial to pave the way for other life forms on the mainland.
An article published in the journal “Proceedings of the National Academy of Sciences” describes a research conducted on five fossils of Chengjiangocaris kunmingensis, a crustacean-like arthropod that lived about 520 million years ago in today’s China. They preserved beautifully, so much that their individual nerves are visible making them the oldest fossils to show such details.
An article published in the journal “Proceedings of the National Academy of Sciences” describes a research that provides evidence that ancient sea sponges were the first animals existed on Earth. A study led by Dr. David Gold of MIT (Massachusetts Institute of Technology) reached this conclusion by analyzing an unusual molecule found in 640 million years old rocks.
An article published in the journal “Palaeogeography, Palaeoclimatology, Palaeoecology” describes a research of truly exceptional fossils because they kept in ancient ocean sediments the traces left in the Cambrian by trilobites and their prey, worm-like creatures. Their analysis reveals the trilobites’ predatory behavior, which was already sophisticated more than half a billion years ago.
An article published in the journal “Historical Biology: An International Journal of Paleobiology” describes various dinosaur fossils discovered in Idaho, USA. Those are several species belonging to the theropod (Theropoda) suborder showing a much greater diversity than was known. The fossils date back about 95 million years ago and according to the team of paleontologists who examined them also include tyrannosaur ancestors.
