At https://www.newsweek.com/ancient-shark-species-discovered-hidden-in-worlds-largest-cave-system-1834492.html … the cave system is in south central Kentucky – accessed in Mammoth Cave National Park. The caves extend for some 40 miles – which includes a lot of branching passages. Some of them are difficult to access and require squeezing through narrow sections. It is difficult to visualise how animals, let alone fish, were washed up into the cave system. However, as in UK caves, numerous animal remains, broken bones and teeth in the main, have been found in caves around the world. In this instance, it was sharks teeth that is at the centre of the tale. It also relies on the uniformitarian scenario of evolution from one form of shark to another form of shark, in order to get an idea of what this new species, with its unusual teeth, may have looked like. The teeth were found in cave sediment but the shark’s time on earth is dated by the geology of the rocks. It doesn’t tell us if the caves were formed after the rock came into existence – or provide much information on that part. I suppose they have to date the shark teeth to some period and the geochronology was the easy explanation.

Geochronology can work wonders when it comes to denying catastrophic events. The Younger Dryas catastrophists associate the wildfires with a bombardment of meteors – a sort of avalanche of tunguska events. Earth, according to Bill Napier, was passing through a dense stream of meteoric material recently outgassed from a giant comet. Interesting idea but open to debate. Landscape fires around the world, at this point in time, would have been induced by atmospheric explosions and impacts of meteors. In fact, the opening line in the title actually gives it away, like a bomb going off. Well, that is more or less a clear description of an atmospheric explosion at low altitude. The nearest analogy would be with a small nuclear detonation.

We also learn that within the La Brea tar pits of California, C14 dating has been applied to some of the bones. It seems these animals suddenly ceased to throw themselves into the seeping tar at a specific point in time that looks like it was the Younger Dryas boundary. In addition, like the caves, a catastrophic event provides the reason why there were so many remains laid down at that point in time -and 100 years is roughly the extent of the Younger Dryas anomaly.
