The big five extinctions are regularly the subject of many investigations, and speculations regarding the causes, the main culprits being often put down to asteroid, or other extra terrestial impacts. Ongoing investigations by paleontologists, together with satellite surveillance, continues to reveal, more and massive impacts , some leaving evidence of 1000 mile diameter crater rims. And this precludes hidden underwater evidence from the Pacific Ocean.
Here`s a brand new take on the subject. Did Earths Gravity change, perhaps more than once, via asteroids , or some other body impacting, and concluding with the Earth, ingesting a massive ultra dense, Nickel Iron Planetary core or cores. Such an object may have been orbiting the Solar System for thousands or even millions of years.
Following a gravitational increase, which would in all probabilities, be accompanied by a reversal of Earths Magnetic Polarity, long and far reaching Gravitational effects would ensue. The pre- nickel iron core ingestion era, of reduced gravity, say of I8 - 22 ft sec/sec provides answers to many puzzling questions. eg. the massive sizes of prehistoric animals, particularly those with outrageously extended necks, that suggest a lower G factor. A , G factor, increase, explains the grounding of many birds that previously flew, albeit with smaller wings, and larger winged / high lift to body ratio hugh flying birds which suddenly could no longer accomplish long journeys, and were suddenly confined to modest sorties. together with the loss of flying reptiles. Also, there is ;
The sinking and entire loss of the Oceanic surface plankton types, resulting in species loss of plankton feeders. eg the Plankton Formentera, an species of fish that sank to a lower oceanic level, effecting the entire predatory chain, ie. a chain of life support obase upon, who eats who, and where ?
One effect of the G plus. effect is that the everything was virtually twice as heavy. Even the air. The entire Earths water table was lowered temporarily, water holes would swiftly disappear for years, until Super G caused Earths Glaciers to accelerate their ice flows, raising sea levels. Gravity is everywhere, you can`t see it, smell it or taste it, there is only one escape. For the amphibious that escape, is displacement in water. The shore dwellers survive, as do the Caymens, Alligators and Crocodiles.
How can we prove or disprove, a Gravitational Increase:
A NEW SCIENCE : DINAFAECEOLOGY / COPROLITE RESEARCH
Until now the subject of coprolite (dinosaur faeces) has been confined to ascertaining the diet of dinosaurs. But now we have three entirely new questions. ( For Paleontologists , Mathmeticians,
and Dynamicists. )
1) How long did specific faeces take to fall ?
2) What was thwere velocity on impact with the ground.
3) And at what rate did those faeces progressively deform, before they ceased motion.
Why ? This is why . This will tell us an unexpected and surprising thing. The afore mentioned questions, will when applied accurately to a sufficiently wide spectra of fossilised faeces. eg or what was the Youngs Modulus ?
Tell us the magnitude of Earths Gravitational Field immediatly prior the extinction of the Dinosaurs
That is to say, fossilied intact, impact deformed dinosaur faeces, and there pre impact deformation state, are possessed of unique and important information, concerning accelleration. .(ie. G )
