Dinosaur extinction
The question is: after the meteorite impact, what happened to the billions of dinosaur bones?
A few days after the impact, the ground must have been covered with millions of rotting corpses, but of their enormous bones there is no trace; the latest finds are below the KT band, strictly logically, the KT band itself should be made up mainly of fossils. What happened to the bones: did iridium from the asteroid or acid rain corrode them? Did overheating of the atmosphere destroy them? Did the surviving animals eat them? Was the fossilization process interrupted? (The heat of the air caused lakes, swamps and streams to evaporate, preventing the first step of the fossilization process: the quick covering of the body with thin materials.) Have any excavations been carried out within the KT band?

Other considerations
One or more asteroids? Was the asteroid that hit the Earth just one or did it split into fragments, as usually happens to large objects? By calculating the trajectory starting from before entry into the atmosphere, is it possible to identify other impact craters? Could there be connections with other impact craters such as the Shiva Crater, in the ocean near India; the Nadir Crater in the Atlantic near Africa; or Boltysh Crater in Ukraine? With the supereruption in the Deccan, India, indicated as an alternative cause of the extinction to the asteroid? Or, could there be a connection to a closer place in Venezuela, the semicircular-shaped Catatumbo Bay, famous for its lightning storms attracted by the large amounts of magnetite in the sand?

Fossil debris
As we saw during the Fukushima disaster, the main effect of a tsunami is to carry everything with it for many kilometers and then abandon it to the ground when the water retreats. With a bit of luck, if we could find valleys or lakes that existed at the time of the impact or other places, such as caves, where water tends to spontaneously flow and concentrate sediments, we may be able to find the last fossils of the last dinosaurs. Perhaps, even in some mountain valleys in the southwest USA or Central America; the funnel shape of the valleys concentrates sediments coming from the valley into thick and resistant cumules. A similar place has recently been discovered in North Dakota. Even on the mountain peaks of Central America there could be some traces; they are very close to the point of impact and it can be assumed that the force of the tsunami was such as to push it to rise up the mountains for tens of meters. Fossils may also be found in the coastal hinterland of West Africa south of the equator, perhaps even of large marine animals that lived close to the coast.

Super mammals
Is it possible that the rock vaporized by the impact, acid rain, billions of dead and decompted plants and animals fertilized the soil with a huge amount of nutrients? As a result of the resumption of life and the restoration of the food chain, does the more nutritious and lush vegetation stimulate the physical growth of all the animal species that survived the impact? After all the effects of the impact had finished, the surviving land animals were insects, small mammals as big as mice, small proto-birds as big as pigeons, and small reptiles such as lizards; based on fossil findings, it has been discovered that in a short time everyone began to increase in size too quickly compared to normal evolution. Reptiles, perhaps due to their cold blood, evolved more slowly while birds and mammals reached large size; then in the evolutionary competition the large birds lost and most of the species became extinct (today there are very few species of bird that live on the ground) while mammals have become the dominant species, some evolutionary branches have transformed into “supermammals”.
