At https://www.livescience.com/animals/sharks/325-million-year-old-shark-graveyard-discovered-deep-within-mammoth-cave-harbors-new-fossilized-species … at Mammoth Cave National Park in Kentucky two new shark species that lived 325 million years ago on the geological column have been found – in what is described as a fossil graveyard. The deposit included other shark species that were already known from elsewhere – and other marine creatures [which are not described at the link]. Obviously, the shark fossils are much older than the mammoths that gave their name to the cave system. They were presumably found in deposits nearer the surface – or on top of old deposits. The shark graveyard is extensive as the cave system is itself an extensive series of passages that are said to extend to 420 miles, or 676 km, in total length . That is a lot of cave – and it is filled with fossils, many of which are yet to be excavated. There must have been a lot of sharks in the sea 325 million years ago. How did they end up in a cave complex? Well, as mainsteam interprets everything on their consensus view of the past they do come up with a theory, of sorts, one that homes into the idea of Plate Theory and uniformitarian geology. We are told that 325 million years ago the Mammoth Cave National Park, which incidentally spreads into part of northern Alabama, was an ancient seaway. This seaway existed prior to Pangaea – when all the continents were part of a single land mass. As in the Cretaceous Seaway that ran across North America, with a direct line down to Chicxulub, this particular seaway may be fancy – a quickly formulated guess that should require some attention. This is a cave system. A shark graveyard in a cave system suggests they were washed into those caves. It doesn’t necessarily mean a seaway existed, pre Pangaea or otherwise. Although a seaway could have existed if the geoid had differed. It sounds as if the sharks and marine life were washed into the cave system – by a tidal wave. Is the evidence of the seaway’s existence the actual passage of that tidal wave? One to think about.
In a non catastrophist view of the past this is not possible and therefore uniformitarians expand the tidal wave in time and motion from a giant splash of ocean water over the continent into a lengthy period under water – utilising uniformitarian dating of sedimentary geology. Hence, the mainstream idea of a seaway is not necessarily what really happened. The theory also relies on the consensus view that Pangaea was a formation that existed on several occasions, coming and going as geochronology has a lot of time in which plate tectonics is thought to have been going on. Hence, in that scenario, there was time and space for a seaway to come into existence – and go out of existence. This diminishes the fact the shark graveyard is found in the depths of a massive cave system in the heart of North America. Is that cave system the squashed up remains of the shrinking seaway? Or did the cave system already exist prior to the burial of all that marine life? One can see that the researchers, and mainstream in general, would like to distance themselves from proponents of Noah’s Flood, who might jump on the bandwagon and claim it as proof of the Bible story. Surely the world has moved on from this – science in particular. How many people in the West believe in Noah’s Flood as literal. How on earth would anyone living in the Near or Middle East know what was going on in other parts of the world, at the time. The story is open to all sorts of interpretation and taking it literally science only continues to give the story breath instead of rigor mortis. I find it all very strange.
Another research discovery involving sharks is at https://www.livescience.com/animals/extinct-species/megalodon-tooth-found-on-unexplored-seamount-10000-feet-below-the-oceans-surface … a submersible remotely operated from a research vessel at the surface, extracted rock fragments from an underwater seamount. Analysis of the rock fragments came upon a megalodon shark tooth. Apparently, these are quite commonly found on the ocean bottom as megalodon’s lived up to 3 million years ago. In other words, they have not been buried too deep in the sediments. Finding one where it had fallen, on a seamount, was novel – hence the story. Sharks renew their teeth on a regular basis and are a common geological find when sifting debris and sediments from continental locations – presumably thrown up by ancient tsunami waves. They are even more common when geologists drag nets across the sea floor in order to bring up sediments.
