Exploding dinosaur hypothesis implodes

re actual explosions are impossible: "Large vertebrates that decompose cannot act as natural explosive charges." And he is convinced: "Our results can be extended to lung-breathing vertebrates in general."

What actually happened 182 million years ago

According to the researchers, the fate of ichthyosaur carcasses can be reconstructed as follows: Normally, the bodies sank to the seabed immediately post mortem. In very deep, hospitable waters, they were broken down completely through putrefaction,scavengers, bone-destroying organisms and dissolving processes. In shallower water (up to 50 meters) and a temperature of over four degrees Celsius, however, the corpses often rose back to the surface on account of the putrefaction gases accumulating inside the body. At the surface, exposed to the waves and scavengers, they decomposed within anything from a few days to weeks and the bones were scattered over a wide area on the seabed as they sank.

Ichthyosaur skeletons only remained preserved more or less in their anatomical position under very special circumstances: A lack of oxygen, medium water depths and insignificant bottom water currents. Because only then were the putrefaction gases compressed strongly enough through the high water pressure and dissolved in the bodily fluids, and the carcasses not completely broken down due to a lack of scavengers. The carcass of the ichthyosaur female from Holzmaden thus sank to the bottom of the sea, which was up to 150 meters deep, where it decomposed. In doing so, the decomposed embryo skeletons were transported out of the body of the mother by minor currents at the seabed.
