An Update On The Triceratops Fossil That Contained Soft Tissue – Proslogion
At a horizon of 40, years the amount of carbon 14 in a bone or a piece of What they got was a date for the shellac, not the dinosaur fossils. Probing a million-year-old T. rex, Mary Schweitzer stumbled upon astonishing signs of What she found instead was evidence of heme in the bones— additional support for the idea that they were red blood cells. A paper published in Science last June presents microscope pictures of medullary . Keep up-to-date on. Mr. Miller told Ancient Origins that it is always desirable to carbon date several fractions Until recently, Carbon dating was never used to test dinosaur bones, as the analysis is only reliable up to 55, years. . aprilholloway's picture.
A few years ago scientists worldwide agreed that no organic material could ever survive beyond thousands of years. There are two possibilities here to explain what is happening. One explanation is that somehow organic matter truly survives millions of years and we did not know it.
The other more reasonable explanation is that these bones are not million years old and that the method used to determine that million year age is flawed. Our research at the paleo group shows that the age determing method is in error. We have carbon dated dinosaur bones from all over the world and they all have easily measurable amounts of Carbon 14 in them.
This proves that the bones are only thousands and not millions of years old. If one does exhaustive research on dating methods one finds that carbon dating is more reliable more studied more widely used than any other dating method. It can also be cross checked by using historical data such as tree ring counting.
Dating methods that give ages in millions of years are more in doubt if one carefully studys the methods and assumptions. Our research has been largely ignored and mainstream science has even refused to test our results by trying their own carbon dating of dinosaur bones. This is not the scientific way, ignoring new information because it does not fit your present ideas!! They have even refused to publish our findings in America. Our team published a paper in Scientific article on dating dinosaur bones in Germany and in the National Research Council of Italy in Scientists have discovered a very large asteroid impact site in Antarctica.
As little as years ago mainstream English speaking scientist did not believe that stones fell from the sky contrary to all the anecdotal evidence over the past centuries. Asteroids are usually referred to as being a solid rock from outer space whereas comets are usually a mixture of ice and rock and typically burn up before hitting the earth.
In a large something from outer space destroyed thousands of acres of forest in Tunguska. Scientist for the last hundred years have been searching for a crator or remnants of space rock. Finally in scientist think they have found an impact site at the bottom of a nearby lake Cheko.
Whats at the bottom might be shattered rocks or impact melt or maybe a piece of meteorite. National Geographic reports that scientist Dallas Abbott from Columbia University has been gathering data and announcing for the past ten years that a giant tsunami deposited ocean floor sediment on Madigascar. The sediments cover an area 2 times the size of Manhattan and are over feet tall. Somewhere in the Indian ocean is thought to be where the giant asteroid struck that produced this giant wave.
More shocking is the fact that the microfossils in this sediment were dated to less than 7, years ago. The really disturbing conclusion is that civilization destroying bolides such as these have happened not millions of years ago but thousands of years ago.
We agree with Dallas Abbott that dangerous meteors have struck the earth in recent times and that the governments of the world should be aware of this fact.
In northern Arizona is a large Meteor Crater, the Barringer Crater, Its well preserved shape suggests a very recent origin. During the last years numerous attempts have been made to determine when this event happened. The age of this event has varied from years ago toyears ago.
It all depends on what age determination method is used and what assumptions are made using the method. The Hopi Indians who live in that area have legends about the meteor's impact. Since they would have been living in the area at the time to have observed and passed on a tradition of the event for posterity, that would limit the impact to less than 10, years ago. It is thought by some to have been the cause of the death of the dinosaurs.
Carbon dating dinosaur bones
Since that is the case if in fact these dinosaurs died as a result of the asteroid hit at Chicxulub then the asteroid hit also only thousands of years ago! Numerous unpetrified dinosuar bones found in Mesozoic strata have been dated and average 31, radio carbon years old.
The Mesozoic strata was laid down at the same time as the dinosaur bones and are the same age. This strata contains hundreds of asteroids which have been identified thus far. Now that we know the strata they struck is tens of thousands of years old and not millions of years old, we can see that asteroids arrive at a rate around times higher than previously projected.
Its arrival was caught on video. The impact was calculated as the equivalent of a blast oftons of TNT. It shattered windows and damaged over 3, buildings and injured people. It could have been a lot worse of course. It points out the imminent danger of another large meteorite or asteroid from outer space wiping out possibly whole civilizations.
An Asteroid labled tc-4 will supposedly miss the earth by miles on October 12,13 of That is terribly close. If that asteroid hit earth the damage would depend on several factors: Consider an asteroid YU55 which came near the earth in If it had struck in the ocean a sunami 60 feet high might have been generated. It is estimated that first degree burns from the fireball would have afflicted people within 60 miles. Could these asteroids have caused the earth to crack and continents to move?
What caused the continents to separate and created many of the mountain ranges of the world. Slowly drifting continents have been the usual explanation for the past 50 years and is generally referred to as Plate Tectonics Theory. In the summer ofshe asked several ostrich breeders for female bones. A farmer called, months later. Schweitzer and two colleagues collected a leg from the fragrant carcass and drove it back to Raleigh. As far as anyone can tell, Schweitzer was right: Bob the dinosaur really did have a store of medullary bone when she died.
A paper published in Science last June presents microscope pictures of medullary bone from ostrich and emu side by side with dinosaur bone, showing near-identical features. In the course of testing a B. One Friday night in JanuaryWittmeyer was in the lab as usual. She took out a fossil chip that had been in the acid for three days and put it under the microscope to take a picture.
She used forceps to flatten it. I was like, stop it! Suddenly Schweitzer and Wittmeyer were dealing with something no one else had ever seen. For a couple of weeks, Wittmeyer said, it was like Christmas every day. In the lab, Wittmeyer now takes out a dish with six compartments, each holding a little brown dab of tissue in clear liquid, and puts it under the microscope lens.
Inside each specimen is a fine network of almost-clear branching vessels—the tissue of a female Tyrannosaurus rex that strode through the forests 68 million years ago, preparing to lay eggs.

Close up, the blood vessels from that T. Of course, what everyone wants to know is whether DNA might be lurking in that tissue.
But DNA, which carries the genetic script for an animal, is a very fragile molecule.
Instead, Schweitzer has been testing her dinosaur tissue samples for proteins, which are a bit hardier and more readily distinguished from contaminants. Collagen makes up much of the bone scaffolding, elastin is wrapped around blood vessels and hemoglobin carries oxygen inside red blood cells. Because the chemical makeup of proteins changes through evolution, scientists can study protein sequences to learn more about how dinosaurs evolved.
And because proteins do all the work in the body, studying them could someday help scientists understand dinosaur physiology—how their muscles and blood vessels worked, for example. Proteins are much too tiny to pick out with a microscope. To look for them, Schweitzer uses antibodies, immune system molecules that recognize and bind to specific sections of proteins. Schweitzer and Wittmeyer have been using antibodies to chicken collagen, cow elastin and ostrich hemoglobin to search for similar molecules in the dinosaur tissue.
At an October paleontology conference, Schweitzer presented preliminary evidence that she has detected real dinosaur proteins in her specimens.
Further discoveries in the past year have shown that the discovery of soft tissue in B. Schweitzer and Wittmeyer have now found probable blood vessels, bone-building cells and connective tissue in another T.

Astrobiology is one of the wackier branches of biology, dealing in life that might or might not exist and might or might not take any recognizable form.
Her NASA research involves using antibodies to probe for signs of life in unexpected places. I really want to know about my dinosaurs. To a fourth-generation Montanan, even the relatively laid-back Raleigh area is a big city.
