With tidal saltmarsh and mudflats, brackish lagoons, grazing marsh and freshwater grassland, as well as arable bird cover, Wallasea is a wildlife haven more than double the size of the City of London. Created using 3 million tonnes of material from London’s Crossrail Project. Helping people connect with nature and coastal heritage, and providing natural coastal adaptation to climate change.

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…
