The paper goes on to describe vessels, bone matrix and elastic tissues, all found somewhere they shouldn't be. Close up, the blood vessels from that T. But now that original dinosaur tissue has been repeatedly confirmed, the existence of biological material and even in allegedly million-year-old specimens should be acknowledged and reassessed. A second line of so-called bird-hipped, or ornithischian dinosaurs, led to a widely differing group of animals that included the stegosaurs and duckbilled dinosaurs. Your article makes another excellent point that deserves highlighting although you did it before. Skeptics claimed it was not dinosaur tissue but actually bacterial biofilm contamination.
At least, that's the conventional wisdom. Then, in 2007, Schweitzer and her colleagues analyzed the chemistry of the T. For the creationist remnant, there's a lot of work to do. And the new findings might help settle a long-running debate about whether dinosaurs were warmblooded, coldblooded—or both. Think of the implications for Christianity.
Red blood cell size is known to correlate with metabolic rate in many vertebrate clades, including reptiles and birds. Opinions of unregenerate scientists are of more consequence than those of qualified creationist scientists. Some skeptics in the past have tried to dismiss claims of soft tissue as mere biofilms left behind by bacteria. Present were several other young-earth creationists as well as numerous seminary theologians and scientists holding the old-earth view. This discovery was made by paleontologist Dr. Heme is a part of hemoglobin, the protein that carries oxygen in the blood and gives red blood cells their color. Measured decay rates of some proteins are compatible with an age of about 4,500 years since the Flood , but not with many millions of years.
© Science Dinosaur Shocker Probing a 68-million-year-old T. The find was also controversial, because scientists had thought proteins that make up soft tissue should degrade in less than 1 million years in the best of conditions. The lectures reignited her passion for dinosaurs. Thus, the age of the gases is on the order of thousands, not millions of years. On the hollow inside surface of the femur, Schweitzer had found scraps of bone that gave a surprising amount of information about the dinosaur that made them. The New Scientist report, , put it: It boasts more than just.
And they need to be tested quickly, as soft tissue could degrade once exposed to modern air and humidity. In the course of testing a B. Then, maybe scientists could use it to create a dinosaur. It was big news indeed last year when Schweitzer announced she had discovered blood vessels and structures that looked like whole cells inside that T. But, I wonder what results would show if a we conducted and experiment closer to the actual conditions for a period of, say, just 10 years? Laura Geggel at Live Science says, Ancient organs rarely fossilize, so paleontologists were stunned to find the incredibly well-preserved remains of a lung that belonged to bird from the dinosaur age. Discovery of soft tissue in Triceratops horn provides additional insight into the nature of fossilization, and extends our understand-ing on the prevalence of preserved original dinosaur tissue. And while old-earthers had hoped they could attribute it to contamination, Dr.
Let her test all she wants. They soaked one group of blood vessels in iron-rich liquid made of red blood cells and another group in water. Evolutionists know that they need to confront this dinosaur soft tissue matter head on, and their responses to date have been far from convincing. But such is the power of the evolutionary paradigm that many choose to believe the seemingly impossible rather than accept the obvious implication, that the samples are not as old as they say. How can Mary Schweitzer's heme concentrated from broken red blood cells explain preserving soft tissue in all the places that such a preparation could never reach? Because of the remoteness and rugged terrain, the bones had to be helicoptered out but were too heavy, so the team reluctantly broke one of the leg bones into two pieces.
Carbon-14 is found in , oil, limestone, , graphite, , , , and even in supposedly billion-year-old! Consider another recent incident involving Christian leaders. They also do the work inside of cells. These changes usually result in a new type of organism better suited for its environment than the earlier type. Using a similar metaphor, I would say that these discoveries of dinosaur tissues etc. If deposition of mineral upon microbial biofilm allowed retention of flexibility in one case, it is feasible to propose that the same process contributed to the preservation of the original vessel walls. The controversial discovery of 68-million-year-old soft tissue from the bones of a Tyrannosaurus rex finally has a physical explanation. Now she has ostensibly tested this idea.
And they need to be tested quickly, as soft tissue could degrade once exposed to modern air and humidity. 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. Indeed, it is hard to imagine how soft tissue could have lasted even 5,000 years or so since the Flood of Noah's day when creationists propose the dinosaur was buried. Red blood cells of humans, like other mammals, are unusual among vertebrates because they lack a cell nucleus. The presence of soft tissue in dinosaur remains and the quandary it presents for evolutionists has fully exposed evolution for what it is; a religious tenet. Maidment, who studies dinosaur motion, was intrigued, too.
