first_imgMore details about the soft tissue found in a T. rex thigh bone (see 03/24/2005 story) were published in Science this week.1  Mary Schweitzer’s team claims to have found evidence of medullary bone [MB], a type of mineralized and vascularized bony tissue found only in certain birds during ovulation as a buffer against calcium loss.  The abstract and summary posted in a press release from North Carolina State says it’s a girl, and she’s pregnant:Unambiguous indicators of gender in dinosaurs are usually lost during fossilization along with other aspects of soft tissue anatomy.  We report the presence of endosteally derived bone tissues lining the interior marrow cavities of portions of Tyrannosaurus rex (MOR 1125) hindlimb elements, and hypothesize that these tissues are homologous to specialized avian tissues known as medullary bone.  Because medullary bone is unique to female birds, its discovery in extinct dinosaurs solidifies the link between dinosaurs and birds, suggests similar reproductive strategies, and provides an objective means of gender differentiation in dinosaurs.   (Emphasis added in all quotes.)Understated in the report is how these soft tissues could have survived for so long.  The paper in Science says only:The existence of avian-type MB in dinosaurs has been hypothesized but not identified.  In part, this could be because of taphonomic bias [i.e., fossil-hunters not expecting to find it], because the death and fossilization of an ovulating dinosaur would be comparatively rare.  Additionally, MB in extant birds is fragile, the spicules separating easily from the originating layer (fig. S1).  Dinosaur MB may separate and be lost from overlying CB in a similar manner during diagenesis [i.e., the hardening of sediment into rock].National Geographic admitted briefly that “all obvious gender indicators vanish when soft tissues decay during fossilization” but emphasized the gender-identification and phylogenetic angles of the story.  The BBC News article showed a picture of the bones, but said nothing about their assumed ages.  The NC press release did not explain the 70-million year figure, but merely asserted it.  Betsy M. Bennett, Directory of the NC Museum of Natural Sciences, stated emphatically, “We’re pleased to be able to provide a way for the public to see for themselves evidence that after millions of years, soft tissue can actually be preserved in dinosaur bone.”    Another paper published in Science Express announced the sequencing of the genome from a cave bear, thought to have been extinct for 40,000 years.  In the BBC News write-up, a scientist predicted, “I don’t think we can extract DNA from dinosaurs, I think they are too old.”  It will be interesting to see if Mary Schweitzer’s team finds any in the T. rex bone, where blood vessels, and possibly blood cells, were seen.1Schweitzer et al., “Gender-Specific Reproductive Tissue in Ratites and Tyrannosaurus rex, Science, Vol 308, Issue 5727, 1456-1460, 3 June 2005, [DOI: 10.1126/science.1112158].This is incredible.  How can these scientists ignore the obvious?  There’s no way this bone could be so old, but all they can think about are connecting homology dots between dinosaurs and birds by circumstantial evidence.  Did they see the dinosaur laying eggs?  No.  Did they prove this is medullary bone?  Perhaps.  Does it prove an ancestral relationship if the dinosaur did have medullary bone?  No.  Does that matter?  Not much.  What really matters about this story is the age of the specimen.  If this specimen is only a few thousand years old, none of this dino-bird homology matters: this blows apart the entire tale of dinosaur evolution.  Belief in millions of years and the rest of the evolutionary timeline takes a staggering blow.    Look at them strain at a gnat about medullary bone, but swallow a camel about the age.  Instead of expressing shock and anguish, instead of repenting in dust and ashes for spreading lies about dinosaur ages for the past century and a half, they grin and say, “We’ll ah’ll be.  Ain’t it amazin’ how these soft tissues survived for sempty millon yeers.”  It makes one think their brainwashing is so complete they would say the same thing if face to face with a living dinosaur.  Absurd?  Not at all: they already do it with living fossils much “older” in their time scheme.    Folks, consider the facts in this story.  Soft tissues from a bone of T. rex, everyone’s favorite monster, were found in Montana.  The specimen preserves fine microscopic detail and even pigment.  The material is still flexible and not fossilized.  We know that medullary bone in living birds is “fragile, the spicules separating easily from the originating layer.”  The initial reaction by the scientists was disbelief, because no known process could preserve soft tissues like this for so long.  (And what a thought to consider that this monster might have been alive just a few thousand years ago!)Though this is a spectacular example, we should not think that it is an isolated case.  Many insects from around the world have been found preserved in amber (fossil tree resin), with even hairs and veins in the wings preserved in exquisite detail.  Some still contain bacteria in the guts and DNA fragments have been extracted.  Often the specimens are indistinguishable from living species, yet claimed to be millions of years old.  Yet we know that tree resin weathers rapidly and is usually not produced in quantities that can extend for meters and entomb frogs and large insects, which would normally float and decay before being preserved.  On what grounds can evolutionists claim such fossils are ancient?  (For more information on fossil amber, get the presentation “Amber – New Insights” by Dr. Harald Binder, available at Access Research Network.)The only way anyone can claim these dinosaur bones are tens of millions of years old is by prior commitment to a belief system that demands forcing all evidence into a long, drawn-out process of evolution.  The young-earth creationists have a great opportunity here.  They and anyone still unbrainwashed about geologic time, and all who respect hard evidence, should hammer away relentlessly at the credulity of the Darwinists, demanding that they explain how a specimen like this could survive even one hundredth of that much time.*  If you see this bone on exhibit at the North Carolina Museum of Natural History, be nice, but come prepared with good questions and reputable background information.  Don’t take bluffing and evasion for an answer.  Undoubtedly, after enough exasperation, they will probably provide the docents a manual on how to deal with those pesky visitors who won’t buy the script, but keep demanding, “Just the facts, ma’am.”**(Visited 17 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

first_imgTwo pilgrims died of cardiac arrest near the holy cave shrine of Amarnath while another was killed in a road accident in Pulwama district, taking the death toll in this year’s pilgrimage to 20. A private vehicle, carrying Amarnath pilgrims, collided with a school bus at Padgampora in the Awantipora area, resulting in death of one woman pilgrim, a police official said. He said she was identified as Savita, a resident of Jaipur. A pilgrim, identified as Mahinder Pal, fell unconscious last night at Kali Mata track and later died, the official said. G. Koteshwara, a 70-year-old pilgrim from Andhra Pradesh, died due to cardiac arrest at the holy cave yesterday, he said. With these, the death toll in this year’s pilgrimage — which began on June 28 — has gone up to 20.last_img read more

first_imgThe political slugfest over the bandh called by Bharatiya Janata Party in West Bengal continued for the second consecutive day on Thursday, with the Trinamool Congress leadership alleging that a shop owner at Keshiary, Paschim Medinipur was killed during the bandh.TMC leaders including Subrata Bakshi and Manash Ranjan Bhunia visited the area and met the family members of the deceased. “Shame on you BJP. Innocent people are getting killed. Surely the state government will stand by the family in this hour of grief,” a TMC statement said.The BJP, however, denied involvement in the violence. Its senior leader Kailash Vijayvargiya said the TMC was trying to defame his party by levelling such allegations.last_img read more

first_imgFirst indications of an alliance being stitched by the smaller political parties for the upcoming Lok Sabha election have emerged in Rajasthan with the Rashtriya Loktantrik Party, formed ahead of the 2018 State Assembly polls, announcing its plan to contest all the 25 seats in association with other parties opposed to the Congress and BJP.The RLP, headed by Khinvsar MLA and BJP rebel Hanuman Beniwal, had won three seats in the State Assembly election. The party had fielded its candidates in 57 constituencies and contested the polls without any alliance.Mr. Beniwal said here on Tuesday that the RLP had not only won three seats, but also obtained a considerable vote share and made an impact on the results in about two dozen Assembly constituencies. The party won Khinvsar and Merta seats in Nagaur district and Bhopalgarh seat in Jodhpur district.The RLP president said the party was trying to enter into an alliance with other parties and discussing the framework of accord with Bahujan Samaj Party, Bharatiya Tribal Party, Communist Party of India and some other smaller political outfits. He said a decision on his own candidature in the Lok Sabha election would be taken after consultations with the party workers and Assembly poll candidates.‘No relief yet’Mr. Beniwal said the Congress, which was elected to power in Rajasthan following its promises made to farmers and youth, had yet to extend relief to vulnerable sections of society. “The loan waiver has not benefited all the eligible farmers, while moong (lentil) procurement is yet to start and the contractual workers in government offices are still waiting for regularisation,” he said.The RLP chief said several promises made in the Congress’ manifesto could have been fulfilled before the election’s model code of conduct came into force. “Evicting the BJP from power has not served the purpose. The ruling Congress is yet to take meaningful action for people’s welfare.”Though the Congress had declared earlier this month that it would have no truck with allies in the Lok Sabha polls, its stance has been perceived as a strategy to put pressure on the smaller parties to accept an alliance on its terms and agree to a limited number of seats.last_img read more
