WHAT CAUSED THE DINOSAUR EXTINCTION?
..No not just a weather woman who was a knockout! No doubt the comet may have had a lot to do with it, but there were worldwide climate changes before the dinosaurs were weakened and knocked out by the one two punch of first weather, then the comet. This is the consensus among the museums and world miners of our time. But why did just the dinosaurs go out and not the mammals and birds? I believed initially the comet might have hit the earth and tilted it causing the seasons and knocking out the (presumably) cold blooded dinosaurs. The mammals and birds would have survived because they were warm blooded. Something must have caused the seasons but it wasn't the comet because info from the impact site shows that it was just a mile wide and the earth has a huge 37,000 mile diameter. And if the comet had hit the earth enough to start the seasons it would have shaken the life of the world so much of the world's life would have literally fallen off the planet. For this reason and that the dinosaurs were showing signs of infirmity for millions of years before the impact, the asteroid may have been the straw that finished the dinosaurs off and started the dromedairys. The tilt of the world that caused the seasons may have had another, more ancient origin, the land bridge between the South America and the Antarctic, this submerged about 87 million years ago about 22 million years before the dinosaur met their fate. In this explanation the Land Bridge Dinosaur Bird Mammal Causology (LBDBM, or LBD) the land bridge when above the waves stopped the tidal bulge of the moon as it would go around and attract the waters of the ocean of the S hemisphere. When the land bridge submerged (it doesn't matter the exact date tens of millions of years before the dinosaur extinction is good enough) a complete flow of the water in the south in it's daily flow of the tides would allow it to flow without as much friction as the more restricted northern oceans were. In LBD this set up the slow precession of the earth in the 25,000 year cycle it's in now. The precession is to the west, and the earth spins to the east, so the precession was caused by other forces before the land bridge submerged. The S tides would just have amplified the spin. In the ages before this the precession would have been at a higher angle and with a reduced period so the momentum was conserved explaining with much more even heat distribution why the dinosaurs fossils are found in both the arctic and antarctic and all other zones of the world.
.
..When the earth was at an angle, the tropical zones may have gotten about the same amount of light via what astronomers assume, so the dinosaurs had reduced room. So this is why I call it the Land Bridge Dinosaur Extinction, or LBD. With the regions above and below the tropics, in the room left by the dinosaurs, with this the mammals and birds suddenly may have found a vast new living realm. Laterite (from the word for brick wall or "lateral") a type of rock only found in monsoon rains, is absent in the time before the late Cretaceous, the time of the dinosaur's doom. This would be because rain takes more temperature change and by the tilting of the earth the weather was more windy (like the autumn and spring winds of our times when the tilt of the earth is most changed) so the birds would have first used the feathers for warmth, and then a way to sail when they jumped farther than others, in the usual way it's believed they took to the air. And the mammals were also warm blooded and well adapted. The flowering seed plants would have also gone north and or south to the large land area left by the dinosaurs, with fast transport of the seeds both by more wind and by the faster animals. Although the flowering seed plants may have gone to the tropics with the dinosaurs they may have had it more of ease to go with the much faster motion of the winds and animal transport so there would be a relatively sharp seperation of the flowering seed plants and the dish of the dinosaurs of the time after the land bridge submerged. Why buy a Box of Cash for 50 when the shelf beside it has hot dish at no cost?
.
..The dinosaurs life in narrower land of just the tropics would also explain why the dinosaurs went extinct and not the mammals and birds. With the dinosaurs already reduced in room by the bad weather and perhaps poor food too, when the comet hit, it would have had dust and fire in a narrow band around the tropics, this perhaps mostly caused by the angle of impact of the comet, but also by the faster spin of the earth of 65 million years ago (it's slower now because of gradual winding out of the tidal friction of the ocean's attraction with the moon.) Why the crocodiles and snakes didn't go extinct but the dinosaurs did may also be of the sort of coincidence of geology about where and how the comet hit. I say coincidence because if the comet had hit either north or south, it would have presumably weakened the birds and mammals but left the dinosaurs mostly unchanged. And the other coincidence that may have saved the other reptiles than the dinosaurs could have just been that the crocodiles and other reptiles were of the opposite side than most of the dinosaurs, so the dinosaurs were hit more than the other reptiles, this is at least one probable explanation that would fit this the LBD causology. No causology other has this following from the main idea, and no other way than this explains both the rise of the mammals and birds and the dinosaur demise. With the dinosaurs being in a narrower and narrower tropical band, there is an explanation about why the dinosaurs of the later Cretaceous when the comet hit had all the plates and bones, otherwise why the late cretacious life like stagasaurus, triceratops, or the hadrosaurs were so unusual might be unexplained. With reduced room, there would have been more interbreeding. And if the dinosaurs were cold blooded and some were living in the northern tropical zones the weather would have been the worst for a dinosaur, so I would explain this by the combination of bad weather and interbreeding. The bones of the triceratops were thought for millions of years to be for fighting but the fossils show that there were so many blood vessels in the nose of the animal, fighting would have caused a sore nose. So they now say the triceratops had the unusual nose because of being like moose of our age. They have horns for finding their own among others in a big neighborhood of lots of wildlife. I think it may just be due to the bad weather, and bad food, ect. Another reason I think the bad weather may have had influence over the weakening of the dinosaurs is because of the stegosaurus, this is the usual dinosaur with plates on it's shoulders. It's thought the plates were to make the body temperature more constant with changing weather, and this is also in keeping with the idea that the weather of the late cretacious was bad for dinosaurs.
..The change in the seasons was caused in my causology by the tides and the tides flex the land in land tides when the moon goes above us. The land tides are the explanation of the power source of most vulcanism and earthquakes. Two thirds of the earthquakes and volcanoes occur within 10 days of the first of the month when the tides are higher, this has been known to geologists since about 1900. If the change in the tides and the tilt of the earth by the land bridge being submerged in the S ocean was associated with tectonics, this may be another cause of the dinosaurs unusual noses in the final dinosaur hours before the comet. With tectonics would be volcanic eruptions of large sort if the whole earth was tilting in a major sort of way, and this would pollute the air, causing the dinosaurs to evolve in unusual ways. So a prediction would be that in the late cretaceous and before perhaps starting somewhat after the time of the land bridge, many of the dinosaurs would have been developing breathing problems and many would have been trying to evolve ways like filters to breathe better.
..The idea of the whole earth tilting would explain why there were so many volcanic eruptions by the above in the age of the dinosaurs (and there would be less in other ages because the dinosaur extinction instability that weakened them wasn't present in other ages). Of course it's not as simple as this. For example the moon was much nearer and causing more tides in earlier ages, and radioactivity from the earth is unpredictable. In general however I think it may be more characteristic of the dinosaur's age than other ages.
..They haven't decided yet from the evidence not yet conclusive if the dinosaurs were cold blooded. In this causology they would be found in later and later ages to be more and more confined to the narrowing of the tropic zone. Since this confinement may also be used to explain the rise of the birds, mammals, and the flowering plants, and why the dinosaurs went extinct by my theory, it also predicts that the dinosaurs were not warm blooded. This would be what would have separated the dinosaurs from the birds, mammals and flowers (there may have been many flowers who evolved with the dinosaurs). So this explains why the dinosaurs went extinct and the birds and flowers and other life flourished.
..A way to prove that the dinosaurs were functionally cold blooded would be comparison with cold and warm blooded life of our era and changes with changes in general weather such as in the pleistocene. Warm blooded life will be able to stay further north. Cold blooded life would stay near the equator so when the N and S icecaps would be caused by the change in precession caused by the land bridge, the dinosaurs would have lived nearer and nearer the tropics, and have the territory like other warm or cold blooded life with the same weather of times like these.
..As you see on this Wikipedia link there is no sharp definition of warm and cold blooded. However there is general definition of worth to this argument. Warm blooded life slows and does somewhat worse in the heat, and cold blooded life can't do well without the heat. This definition is not precise (by the definition we are cold blooded ourselves) but if the dinosaur extinction was indeed related to change in the weather though general it would be a definition of use.
..If the earth was more level with the ecliptic in the Triassic and the Jurassic without the seasons, most of the world would have had year round weather like the tropics and the N and S would have been like california. By the general definition of warm and cold blooded the dinosaurs would have had a much more vast region of good weather in which to roam in what would now be the N and S temperate zones. It's possible like humans they would have had a level of heat above which they would have slowed metabolism. This would explain why there are no huge animals in the tropics at this time, and fewer, slower, giant dinosaurs in the tropics might be possible if they were indeed warm blooded and it was hot. Most of the dinosaurs may have gone N and S and been huge even if they were what's called cold blooded.
..The dinosaurs were the largest animals by far that have lived on earth. No other animals have reached near this size. Why is this so? "They were more by far than all other land animals before or since". If they had a larger gene pool from 228 million years ago because of one, more unified land (before contenental drift) the advantage of size would have been more of worth if there was more energy in the plants caused by the good weather when they were evolving in the Triassic to support the massive weight of the dinosaurs. This predicts that on islands where there were not many dinosaurs (the same with other animals) over geologic time there would have been smaller size. And if the land was then more seperated by contenental drift, this may have made the gene pool of the dinosaurs smaller and caused the peculiar skulls and other features like the plates of the stagasaurus not seen elsewhere in evolution (this may be caused by some unusual cause like changes in weather not common to evolution). At any one time, it's estimated there were just 5 or 10 T Rex's roaming around N. America. This may have caused fragility to the dinosaur ecology because predators are needed to keep an ecosystem from instability and then weakness (It's an old proverb that when the Boss is away, the mice will play, they are mice who save much!). With more ill health caused by this and other changes like the bad weather of the Cretacious, the impact by the asteroid would have been the knockout punch to cause the dinosaurs demise. (Land Bridge Dinosaur Extinction LBDE would also explain why the contenents began to drift at any rate, why not before? With the land bridge constantly causing torque and techtonics a prediction in favor of this cause of the Dinosaur extinction LBDE is there would be fewer global siesmic events before the land bridge. The continents have continued to drift since then because the seasons are constantly causing heating and volcanoes and earthquakes, why no more heat or less? A mild cause like the tides would be most optimal, with constant flow from then to now over geologic time. If it were caused by radioactivity, it would have overburned or underburned instead of the more constant flow seen with contenental drift, as if caused by a more continuous flow of heat, like the tides. This idea would seem to need an equivalent force to the heat output of the contenental drift, by energy conservation.)

.. The dinosaurs wouldn't have been evolved to adapt. The dinosaurs would have been more like an evolutionary dead end, like an overevolved battleship facing newer machines and the mammals and other life would have survived because they weren't so overprogrammed they would make a better start. They didn't have so much or so much to lose, rather like the Contentental Army in America's war in 1776 with the British. If the good weather was mostly before and when the dinosaurs roamed, it might be like our own evolution they now find there was no real definite divine right of humans to win over the rest of the world's life. Like business and the heartbreak of housatosis, no sure path may be for life in evolution. There was the great extinction that was just before the age of the dinosaurs at 228 million years ago. And at least 30 known ice ages of the Paleozoic are known, the age of fish and coal before the dinosaurs, this would limit the evolution. Some life had to be first, and the dinosaurs would have won first when weather was good. Later evolution would have always been limited by the winters in size of life forms like the mammals.
..While it's thought that the dinosaurs were mostly warm blooded because the most warm blooded animals, the birds, are descended from them, we're all descended ultimately from a common cell or ancestor and this is no proof the cell or ancestor was warm blooded. The dinosaurs would be more "cold blooded" and this would explain the extinction by way of the comet. The warm bloodedness of birds and mammals and feathers and air travel of birds in evolution would be an idea whose moment had arrived.
..While the amount of size a dino would put on a year was like a warm blooded animal, and this is the main evidence that convinces many of the dinosaurs being cold blooded, thanks to the good weather and range, I think they may have put on weight at a warm blooded rate without actually being warm blooded.
..Tracks may be of worth to find out if the dinosaurs were warm blooded. Mammals have typically a lower metabolic activity in the tropics and in the far N and S with a peak when the weather is moderate in the temperate zones (for example a human's metabolism is 25% lower in the tropics). Metabolism of cold blooded animals has a peak in the tropics and falls off more rapidly in the N and S zones. If you go out on a hot day you won't see many people running fast, if it's a high speed marathon, both the road and the runners walk, or in real hot weather the road is perhaps a lava flow where I live! Unlike reptiles, warm blooded mammals and other ectotherms have a fire burning inside so they have to slow up to not overload in the heat. Foot impressions (size triple 1000) may be a way to see how warm or cold blooded the dinosaurs were. A dinosaur in the tropics if warm blooded would have to slow down in the heat so would take fewer steps and the same dinosaur if in the zones of more heat but not cool would take more giant steps. A cold blooded dinosaur (in the more general sense of the definition) would take more steps in the tropics and it would follow the motif of metabolism in general. At night with more of their own heat to go on the dinosaurs if warm blooded would be more nocturnal in general all else the same. By comparing physiology of life adapted to nightlife and wild celebrations of the present, this could be used to prove or disprove this such as dinosaurs with eyes adapted just to see at night and would be evidence for or against this about the dinosaur's demise because of poor adaptation to the weather and thus the rise of the birds and mammals.
