Scientists have unearthed an almost perfectly preserved spider fossil in China dating back to the middle Jurassic era, 165 million years ago. The fossilized spiders, Eoplectreurys gertschi, are older than the only two other specimens known by around 120 million years.
The level of detail preserved in the fossils is amazing, said paleontologist Paul Selden of the University of Kansas and lead author of the study appearing Feb. 6 in Naturwissenschaften. â€śYou go in with a microscope, and bingo! Itâ€™s fantastic.â€ť
The fossils were found at a site called Daohugou in Northern China that is filled with fossilized salamanders, small primitive mammals, insects and water crustaceans. During the Jurassic era, the fossil bed was part of a lake in a volcanic region, Selden said....
Did you see that an attempt was made to explain that soft tissue as some sort of 'biofilm' and thus dispatch with it? Mary Schweitzer (the original discoverer of the tissue) upheld her original conclusions.
The story you mention was also featured in the May 2006 Smithsonian Magazine. It has one of my favorite quotes, "Even after 68 million years, these dinosaur remains look surprisingly fresh under Schweitzerâ€™s microscope." Classic!
What an odd thing to say. Mainstream science has been pretty darn sure the earth is at least billions of years old since radiometric dating got enough data points, well before WWII.
The measure of a person's reasonableness is not how stubbornly one clings to an ideology. It's one's genuine willingness to discard a dearly held belief, and to change one's mind to fit newly learned facts and data. That is what really makes one person more reasonable than another person.
There may always be pocket bastions of ideological beliefs. But hopefully the world as a whole will eventually see them as irrelevant.
The Earth sure has aged fast. In 1961 it was only 50 million yrs. old, now it's over 165 million yrs. old. How did they find out how old the spider was? Simple; the rock they found it in was 165 millionm yrs. old. How did they find out how old the rock was? Simple; the spider they found in it was 165 million yrs. old. Ther'e playing the old Billy Preston song; "We'll go round in circles".
Excellent. I always wanted to know what a 165 million year old spider looked like. Let's see..... Eight legs, an abnormal amount of eyes, big hairy body... Yup, it's a spider. Always has been a spider, always will be.
The paleontological community has now been confronted with soft tissues in fossils, something creationists have been ridiculed for claiming before: T Rex bones yield soft tissues
Organic molecules should not last over 100K years, so either this theory is manifestly false, the organic molecules really are lithified despite all appearances, or else fossil dating methods are ridiculously flawed.
All scientific claims (whether about the past or present), stumble over basic formal logic; esp. induction & affirming the consequent. But one has to accept the primacy of logic, something many Christians seem uncomfortable with.
