BOATLOAD OF EROSION. “Their evidence implies a culprit behind all of the missing rock: global tectonic uplift associated with the breakup of the ancient supercontinent Rodinia. This means there was probably a boatload of erosion. The timing of the GU’s formation may also help explain what triggered the so-called “snowball Earth” glaciations, an episode beginning about 720 million years ago in which much of the planet likely became covered in ice sheets.’ https://lnkd.in/ddDSSXe View in LinkedIn

WHAT IS A NANOBE? “A nanobe is a tiny filamental structure first found in some rocks and sediments. Some scientists hypothesize that nanobes are the smallest form of life, 1/10 the size of the smallest known bacteria. No conclusive evidence exists that these structures are, or are not, living organisms, so their classification is controversial.” Found 3 miles below the seabed in rocks. https://lnkd.in/eckY5qA View in LinkedIn

MASSIVE UNDERSTATEMENT. “We conclude that the Phanerozoic sedimentary record is best explained by a Great Unconformity of inherently coupled erosive and constructive genesis, with Neoproterozoic glacial erosion governing the subsequent history of continental freeboard and sediment accumulation. As such, the environmental and geochemical changes that led to the diversification of multicellular animals may be considered a direct consequence of Neoproterozoic glaciation.” https://lnkd.in/d6fatHN View in LinkedIn

"NANOBE structures have been found within organisms as well as rocks. While their existence is relatively new knowledge, some speculate that nanobes may even outnumber bacteria by an order of magnitude." https://lnkd.in/dBbSDUB View in LinkedIn

TECTONICS. “Before the plate tectonic revolution, the missing sediments from Walcott’s “Lipalian interval” were generally expected to reside in the ocean basins; their absence, along with the young age of the ocean crust, was considered a significant point of evidence in favor of seafloor spreading and plate tectonics. In a plate tectonic model, much sediment accumulated on the oceanic crust is consumed by subduction—presently at a rate of about 1.65 km3/y. Due to its low density and fusibility, however, subducted sediment in the mantle wedge is often incorporated into new arc magmas; consequently, a chemical or isotopic signature of subducted sediment (if sufficiently voluminous) may be preserved within the igneous record.” https://lnkd.in/d6fatHN View in LinkedIn

HOW WILL NASA know when it sees a new life for different than that on earth? By asking the wrong question, you risk missing the hidden answer. Water? Carbon? DNA? Probably not relevant. View in LinkedIn

MASSIVE LOSS. “In either a constructive or a destructive endmember scenario, if global sediment supply from tectonic uplift is held constant near Phanerozoic levels, then the depressed Proterozoic sediment volume in Fig. 1A suggests that on the order of 109km3 of sediment are absent from the continental crust and deposited instead in the deep ocean basins—either gradually, throughout the Proterozoic due to a diminished sediment storage capacity of the continents in a constructive model, or rapidly during an interval of enhanced erosion near the Proterozoic–Phanerozoic boundary in a destructive model.” https://lnkd.in/d6fatHN View in LinkedIn

EXPECT THE UNEXPECTED. "In contrast with popular theories of evolution, in which evolution is defined with respect to given symbolic genes and rules such as for replication or recombination, a proper theory of evolving life must allow evolution to create new symbolic descriptions and rules to manipulate them." https://lnkd.in/dsMZPii View in LinkedIn

‪“These excursions, the Great Unconformity, preservational irregularities in the terrestrial bolide impact record, and the first-order pattern of Phanerozoic sedimentation can together be explained by spatially heterogeneous Neoproterozoic glacial erosion totaling a global average of 3–5 vertical kilometers, along with the subsequent thermal and isostatic consequences of this erosion for global continental freeboard.”‬" "‪https://lnkd.in/d5waTiU View in LinkedIn

SUPPORTING DATA. “Here we show that the Great Unconformity is associated with a set of large global oxygen and hafnium isotope excursions in magmatic zircon that suggest a late Neoproterozoic crustal erosion and sediment subduction event of unprecedented scale. These excursions, the Great Unconformity, preservational irregularities in the terrestrial bolide impact record, and the first-order pattern of Phanerozoic sedimentation can together be explained by spatially heterogeneous Neoproterozoic glacial erosion totaling a global average of 3–5 vertical kilometers, along with the subsequent thermal and isostatic consequences of this erosion for global continental freeboard.” https://lnkd.in/d6fatHN View in LinkedIn
