Pre-Cambrian sponges, world’s oldest animals discovered

https://youtu.be/28uYZED4TDk This July 2013 video says about itself: A number of sponge-like fossils occur in the fossil record, many of which were originally described as sponges. A few of these are presented here. Charles D. Walcott was one of the first paleontologists to get involved with many of these, some of which are found in very ancient strata of the Precambrian. Walcott’s Atikokania was one of these, it’s now considered to be a pseudofossil (false fossil) much like the previously described Eozoon canadense (the so called “Dawn Animal of Canada”). Sponges are an ancient group of animals; however, their presence before the Cambrian Period is questionable. That was then. However, now … From the University of California – Riverside in the USA: Sponges on ancient ocean floors 100 million years before Cambrian period Molecular fossil evidence October 15, 2018 Researchers at the University of California, Riverside, have found the oldest clue yet of animal life, dating back at least 100 million years before the famous Cambrian explosion of animal fossils. The study, led by Gordon Love, a professor in UCR’s Department of Earth Sciences, was published today in Nature Ecology & Evolution. The first author is Alex Zumberge, a doctoral student working in Love’s research group. Rather than searching for conventional body fossils, the researchers have been tracking molecular signs of animal life, called biomarkers, as far back as 660-635 million years ago…

Jupiter and Titan findings underpin troubling news about Earth methane emissions

New modelling suggests estimates for methane’s role in global warming are on the low side. Richard A Lovett reports. Donald Trump during a rally earlier this year, spruiking his intention to repeal Obama-era laws aimed at reducing methane emissions from fossil fuel extraction. MANDEL NGAN / AFP / GETTY IMAGES https://cosmosmagazine.com/climate/jupiter-and-titan-findings-underpin-troubling-news-about-earth-methane-emissions Scientists seeking to refine our understanding of global climate change have found that methane is a significantly stronger greenhouse gas than previously suspected. They have also discovered that it has particularly strong climate-warming effects on certain parts of the globe, including Australia’s deserts. The finding evolved, in part, from data collected by astronomers studying Jupiter and Saturn’s moon Titan. And it comes, ironically, just days after US President Donald Trump’s latest move to reduce regulations on methane emissions from U.S. oil and gas fields. Like carbon dioxide, methane has long been known to warm the atmosphere by absorbing infrared emissions from sun-warmed surfaces — emissions that would otherwise carry heat back into space. And while there is much more carbon dioxide in the atmosphere than methane, the latter is a much more potent heat trapper. It is so potent, in fact, that increases in methane may have accounted for more than one-fifth of the Earth’s climate change over the past century. And that estimate might actually be too low, because it is based solely on methane’s ability to trap thermal, or “longwave”, infrared radiation. Thanks…
