New research from North Carolina State University shows that iron may play a role in preserving ancient tissues within dinosaur fossils, but also may hide them from detection. The finding could open the door to the recovery of more ancient tissues from within fossils. Mary Schweitzer, an NC State paleontologist with a joint appointment at the N. C. Museum of Natural Sciences, first announced the surprising preservation of soft tissues in a T. rex fossil in 2005. Her subsequent work...

Blood-Filled Mosquito Fossil Discovered By Researchers

redOrbit Staff & Wire Reports - Your Universe Online Researchers report that they have found a fossilized mosquito specimen that was still blood-engorged from its last meal – a discovery that is detailed in the latest edition of the journal Proceedings of the National Academy of Sciences. The mosquito had been preserved in shale rock for approximately 46 million years after it plummeted into a lake in what is now northwestern Montana, according to Joseph Stromberg of...

A paleontologist at North Carolina State University says she has discovered new evidence to support the idea that soft tissue and proteins can be preserved over long periods of geological time after a protein sequence was recovered from an 80 million-year-old duck-billed hadrosaur. Dr. Mary Schweitzer, along with colleagues Dr. John Asara of Beth Israel Deaconess Medical Center and Harvard Medical School, Dr. Chris Organ of Harvard Medical School, and a group of researchers from Montana State...

A team of researchers led by a North Carolina State University scientist has found soft tissue on a dinosaur skeleton. The team was led by Professor Mary Schweitzer, who in 2005 found soft tissue in the fossilized bone of a 68-million-year old Tyrannosaurus rex, The (Raleigh, N.C.) News & Observer reported Thursday. The findings will be published this week in the journal Science. As was the case with the T. rex bone, there was no DNA found to give scientists a glimpse into the giant...

By Zoe Elizabeth Buck, The News & Observer, Raleigh, N.C. Jul. 31--A fossil researcher at a Washington state museum has triggered doubts about the discovery of Tyrannosaurus rex tissue by N.C. State paleontologist Mary Schweitzer. Three years ago, Schweitzer's team gained international headlines with the news they had uncovered the thigh bone of a 70 million-year-old dinosaur in Montana with what appeared to be blood vessels and maybe even whole cells embedded inside. The discovery...

By Dan Vergano New research is challenging claims made three years ago that scientists had discovered soft tissue remnants in the thighbone of a Tyrannosaurus fossil. A group led by paleontologist Mary Schweitzer of North Carolina State University in Raleigh garnered headlines in 2005 for reporting in the journal Science that they had found the remains of blood vessels inside the fossils unearthed in the Hell Creek Formation in Montana. Finding tissue preserved at least 65...

Scientists who dig dinosaurs in Eastern Montana will now be able to chemically analyze fossils the same day they're excavated and before degrading begins.Paleontologists from Montana State University, North Carolina State University and the North Carolina Museum of Natural Sciences recently bought and renovated a mobile laboratory that Dan Redding of Rudyard drove to Eastern Montana for the summer.The lab is the first of its kind and a dream come true, said Mary Higby Schweitzer, a North...

Dinosaurs may have been more closely related to chickens than reptiles, according to a report released on Thursday.Researchers John Asara and colleagues at Beth Israel Deaconess Medical Center and Harvard Medical School in Boston sought to fill in the gaps of the dinosaurs' family tree.Molecular analysis, or genetic sequencing, of a 68-million-year-old Tyrannosaurus rex protein from the dinosaur's femur confirms that T. rex shares a common ancestry with chickens, ostriches, and to a lesser...

It's a girl - and she's pregnant! Paleontologists at North Carolina State University have determined that a 68 million year-old Tyrannosaurus Rex fossil from Montana is that of a young female, and that she was producing eggs when she died. The proof, they say, is in the bones. In a case of a literal "lucky break," the scientists discovered unusual bone tissue lining the hollow cavity of the T. rex's broken leg bone. In a paper published in the June 3 issue of the journal Science, Dr. Mary...

John R. “Jack” Horner (born June 15, 1946) is an American paleontologist known for his research on dinosaur growth, and for discovering evidence that some dinosaurs nested and cared for their young.  He is perhaps the most famous paleontologist due to his role as technical advisor for all three Jurassic Park films, and his providing inspiration for Dr. Alan Grant, the film's lead character. He also advised on the FOX television show Terra Nova. Horner was born and raised in the small...
