Refuting Creationism - How Storms Created A Dinosaur Fossil Site - 80 Million Years Before 'Creation Week'

Tethyshadros insularis and crocodilians struggle against a violent monsoon storm.

Storms that built a graveyard: ancient monsoons created a spectacular dinosaur fossil site

Young-Earth creationists are fond of pointing out that a single flood or storm can deposit a layer of sediment very quickly, as though this somehow proves that the entire geological record could have been produced during the mythical year-long flood described in Genesis. But the speed with which an individual layer forms tells us nothing about the intervals between successive layers. When those layers contain regular, measurable cycles produced by processes operating daily, fortnightly and seasonally, they become a record of elapsed time—and that time cannot simply be waved away.

An article in The Conversation by palaeontologist Alfio Alessandro Chiarenza of University College London describes just such a record. It concerns the Villaggio del Pescatore fossil site near Trieste, north-eastern Italy, where dinosaurs, crocodilians, fish, shrimps, plants and other organisms were preserved with exceptional detail about 80 million years ago.

Chiarenza and his colleagues, led jointly with Federico Fanti of the University of Bologna, have published their findings in the journal Global and Planetary Change. Their evidence shows that the site was not, as previously proposed, a quiet lake or sinkhole. It was a tropical tidal flat on the edge of an ancient sea, repeatedly affected by powerful monsoon floods and tropical cyclones.

The fossil-bearing limestone consists of metre-thick packages containing thousands of discrete, paper-thin light and dark layers. These had previously been interpreted as annual deposits, or varves. However, high-resolution synchrotron X-ray scanning, microscopic and geochemical analyses, and statistical analysis of the repeating patterns revealed something still more remarkable: the layers are tidal microcouplets, laid down under a semidiurnal tidal regime—two tidal cycles each day.

Moreover, variations in the thickness of the layers follow the familiar fortnightly alternation between spring and neap tides. The rocks therefore contain not merely a succession of vaguely similar bands, but an ordered astronomical rhythm produced by the interaction of Earth’s rotation with the orbit of the Moon. By counting and analysing those layers, the researchers calculated that the fossil-bearing succession accumulated over approximately 40 years. In other words, the rock preserves an almost day-by-day record extending across four decades.

That presents creationists with a problem that cannot be dismissed by claiming that “floods can deposit sediment rapidly”. Of course they can; that is precisely what some of the layers record. But a single flood cannot manufacture 40 years’ worth of successive twice-daily tidal deposits, arranged in the correct fortnightly spring–neap pattern. Still less can the supposed year-long biblical flood accommodate a geological sequence that records some 40 years of tides within one small part of a vastly larger, 80-million-year-old succession.

Refuting Creationism - A Rhino From The Canadian Arctic - 23 Million Years Before 'Creation Week'

Another day, another incidental refutation of the childish biblical creation myth.

This one comes, as so many do, from scientists doing what scientists do best: uncovering the facts and following the evidence wherever it leads.

In this case, the evidence shows that a species of rhinoceros was living in the Canadian High Arctic about 23 million years ago. Even more significantly, the find suggests that rhinoceroses, once widespread across Eurasia and North America, crossed into North America far later than previously thought, by way of northern land connections that remained viable well into the Cenozoic.

Scientists from the Canadian Museum of Nature have just announced the discovery of the species they named Epiaceratherium itjilik in the journal Nature Ecology & Evolution.

The discovery creates problems for creationism on several fronts. Most obviously, its age places it far outside the tiny timescale permitted by creationist mythology. It also demolishes the notion that modern animal distributions can be explained by descent from a single surviving pair a mere 4,000 years ago, because no such recent land bridge existed to carry rhinoceroses into North America. Instead, the fossil fits neatly into the well-established evolutionary history of rhinos, which stretches back roughly 40 million years, and into the geological evidence for changing sea levels and intermittent northern land connections between Eurasia and North America. These independent lines of evidence converge for the simple reason that they describe what really happened.

The fossilised remains, representing about three-quarters of a skeleton, were recovered from the rich fossil deposits of Haughton Crater on Devon Island, Nunavut. The animal is now the northernmost rhinoceros species yet known, and its excellent preservation has given palaeontologists an unusually complete picture of this unexpected Arctic browser.

Refuting Creationism - How Camellias Evolved As The Japanese Islands Formed

It's a basic principle of evolution that environmental changes drive evolution by isolating populations which are then free to evolve on their own trajectory, and by creating new ecological niches into which species can diversify.

An almost perfect example of this in progress can be seen in the Camellia group of plants, of which one, tea, Camellia cinensis is perhaps the most important economically, But several others are also important cultivated garden plants with bright red, pink or white flowers.

Another phenomenon of evolution that this group of plants displays is that evolution is not a sudden event but a slow process over time, during which hybridization and gene flow between related species occurs until barriers to hybridization have evolved.

This tendency to form hybrids and the general similar morphologies has made accurate classification of the different species, and subspecies difficult and a matter of debate among taxonomists and botanists.

Now work by a team led by Dr. Harue Abe of Niigata University, Sado, Niiagata, Japan have shown how the evolution and distribution of this genus was strongly influenced by the formation of the Japanese archipelago.

Refuting Creationism - How Dynamic Geology Influenced Early Civilisation

Researchers at Woods Hole Oceanographic Institution have shown, in a paper just published in PLOS ONE, that the rise of Sumerian civilization in Mesopotamia was strongly influenced by the dynamic interplay of tides, rivers, and sedimentation at the head of the Arabian Gulf. In doing so, they remind us just how parochial and derivative the culture that produced the origin myths in Genesis really was.

According to Genesis — which places the Middle East, and the Hebrews in particular, at the centre of everything — humans were created fully formed, without ancestry, in a ready-made Bronze Age civilisation.

Within just five generations of a supposed genocidal global flood that allegedly reset life on Earth, eight survivors are said to have produced a population large and skilled enough to embark on a massive civil engineering project: building a tower up to Heaven. In this worldview, Heaven lay just above the clouds over the Middle East, on a flat Earth watched over by a creator god who could apparently be taken by surprise.

Meanwhile, several other ancient civilisations were continuing uninterrupted, apparently unknown to the author of Genesis — despite the fact that some of the stories in Genesis are clearly derived from older Mesopotamian and Egyptian myths. Both the genocidal flood myth and the Tower of Babel narrative draw directly on Mesopotamian sources: the flood from the Epic of Gilgamesh, and the tower itself from the Great Ziggurat at Ur.

What the Genesis myths fail to acknowledge is the fundamental role of geological and environmental change in shaping human civilisation. The authors of these myths believed they lived in an unchanging world, created especially for them by a perfect god. There is no hint of plate tectonics shifting continents, no awareness that volcanic gases can alter climates, or that major rivers can change course or silt up. Yet such processes could and did disrupt the regular flooding on which early agriculture depended. Silting and delta formation could leave once-coastal communities stranded inland, while blocking the twice-daily tidal ebb and flow that once reached deep upriver.
