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...

April Flowers for redOrbit.com - Your Universe Online A new study from North Carolina State University (NCSU) and the Palo Alto Research Center (PARC) reveals new evidence for the preservation of ancient dinosaur proteins. This new evidence includes reactivity to antibodies that target specific proteins that are normally found in bone cells of vertebrates. Further, the study findings rule out sample contamination, and solidify the case for the preservation of cells and possibly DNA in...

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...

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...

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...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
