Dinosaur Sex and Other Tales
July 24, 2007
How much do we really know about dinosaurs? How much can be inferred from their bones? Two recent stories illustrate conflicting themes: much of what we thought we knew was wrong, but that doesn’t stop evolutionary paleontologists from speaking with confidence. Walking with dino ancestors: Paleontologists used to think that the alleged precursors of dinosaurs […]
Chinese Eat Dragon Bone for Health
July 4, 2007
Chinese villagers dig up dinosaur bones for health food. Yahoo News reported, “Villagers in central China dug up a ton of dinosaur bones and boiled them in soup or ground them into powder for traditional medicine, believing they were from flying dragons and had healing powers.” The article says the bones are calcium rich and […]
Imaginary Dinosaur Feathers Found Again!
June 13, 2007
Last year, we reported that imaginary feathers had been found on a dinosaur fossil (see 02/08/2006). Now, more imaginary feathers have turned up. This turkey was big, too: the dinosaur plumed in the imaginary feathers stood almost 12 feet tall. Everyone’s talking about it: Fox News, MSNBC News and Science News among others. National Geographic […]
Dino Feathers or Horsefeathers?
May 23, 2007
The much-touted feathers on certain dinosaurs may be nothing more than collagen fibers. An article on ABC France says “Dinosaur ‘feathers’ are no such thing.” Instead, it’s just decayed dermal collagen, like that found on sharks and reptiles. A South African team came to this conclusion after analyzing the alleged feathers on Sinosauropteryx. […]
Jurassic Park Gets Overhaul
April 17, 2007
How much do we understand the dinosaurs? ABC News reported on some big-time updates and revisions being made to the Carnegie Museum of Natural History dinosaur exhibits. The title of the article is, “Getting Their Dinosaur Facts Right, at Least for Now.” The problem is that even though the newest of the dinosaurs are 65 […]
Proteins Found Preserved in T. rex Bone
April 12, 2007
Preserved fragments of collagen have been found in a dinosaur bone alleged to be 68 million years old. Read all about it in Science Daily. Analysis of soft tissue found by Mary Schweitzer and team turned up the recognizable protein fragments. Protein was also detected in soft tissue from a mastodon said to be half […]
New Dinos Found; What Do They Mean?
March 27, 2007
There is often a wide gap between the bones that are found and the stories that are told about them. As new dinosaur bones come to light, some reporters cannot resist imagining all kinds of things about their lifestyles. Here are two recent examples. As a bonus, we’ll add a non-dinosaur reptile story or two. […]
Evolutionary Predictions Fail Observational Tests
March 8, 2007
Lately, some expectations by evolutionists have not been fulfilled. Here are several recent examples of evolutionary upsets: Dinobird genes cook up scrambled eggs: Scientists expected that the dinosaurs presumed ancestral to birds would show a decreasing genome size. The thinking was that the cost of maintaining a large genome takes its toll on flight. In […]
Dino Horns: Is Smaller More Evolved?
March 5, 2007
One can never tell which way the evolutionary path will take to determine fitness. Could be bigger, could be smaller. Could be faster, could be slower. Could be better camouflaged, could be flashy. Michael Ryan (Cleveland Museum) decided that shorter horns on his dinosaur constituted better fitness. CNN says his discovery, a 20-foot dinosaur in […]
First Euro-Stegosaur Found
February 4, 2007
A Stegosaurus fossil has been found in Portugal, reported Live Science. Previously this species with its spiked tail and prominent rows of plates on its back was only known from North America. A tooth, some leg bones and part of the backbone have been unearthed. So far, the fossil looks indistinguishable from its North American […]
Dinosaur Fight or Common Fate?
January 17, 2007
A fossil discovery by amateurs in Montana, reported by the Great Falls Tribune, shows “a meat-eater and a plant-eater – with their tails crossed like swords.” The fossils show “remarkable detail, right down to tendons and teeth.” The three amateur discoverers had been scouting on private property in Garfield County. Finding bone fragments on a […]
Big Dino Found, But How Did it Eat?
December 21, 2006
A few interesting dinosaur stories came to light this month. I was a Spanish monster: A new giant sauropod has been found in Spain, reported EurekAlert based on a paper in Science.1 Named Turiasaurus riodevensis by the discoverers, it ranks among the largest of dinosaurs and is the first giant sauropod found in Europe, weighing […]
Dinosaur Skin Found, Possible Soft Tissue
November 23, 2006
A mostly-complete duck-billed Edmontosaurus dinosaur has been found in Montana, reported the Discovery Channel. A patch of skin from the hip was recovered. The team from North Carolina State University and Museum of Natural Sciences was very careful. They wanted to preserve any possible soft tissue, using techniques developed by Mary Schweitzer that last year […]
Dinosaur Bone Soft Tissue Questioned, Defended
November 11, 2006
The subject of soft tissue in dinosaur bones came up at the Society of Vertebrate Paleontology Meeting earlier this month, reported Science.1 Mary Schweitzer was there, defending her spectacular claim that she had discovered both medullary bone (06/03/2006) and soft, pliable blood vessels and cartilage in a T. rex leg bone (03/24/2005). Doubters, however, brought […]
Dinos Not Killed Off by Meteor, but by Worms
October 24, 2006
Confident speculations that a big meteor hitting southern Mexico caused the mass extinction of the dinosaurs appear to be unraveling. Gerta Keller [Princeton, 09/25/2003], a doubter of the story that has been a leading contender for years with its smoking-gun crater called Chicxulub in the Yucatan, has been getting a receptive hearing among geologists with […]
