Archaeopteryx Fossil Retains Original Soft-Tissue Material

May 10, 2010

We are usually told that fossils involve the complete replacement of original living material by rock, except in rare cases (such as amber), because organic material is quickly destroyed. One of the most famous rock fossils is Archaeopteryx, the bird that has often been claimed to be a missing link from dinosaurs. An international team […]

Dino-Feather Story Gets Fluffier

May 1, 2010

Xing Xu is at it again, claiming that dinosaur feathers are found everywhere – in China, at least, where the bulk of “feathered dinosaur” claims keep turning up in farmyards. The latest claim is that “Feather structures in maturing dinosaurs changed as they grew.” This story is accompanied by artwork showing the critters looking as […]

Dinosaurs Lived in Vast Ecological Zones

April 24, 2010

Don’t think of dinosaur species living in small ecological zones. Their habitats covered vast areas, according to a new study: “Researchers at McGill University are unlocking the mysteries of the little-known habits of dinosaurs in discovering that the entire western interior of North America was likely once populated by a single community of dinosaurs,” reported […]

How Much Can One Bone Say?

March 26, 2010

Two fossil discoveries are generating a lot of news from a single bone. The first is a dinosaur hip. The second is a human finger. How much weight can a single bone carry? Australian tyrannosaur: The tyrannosaurid dinosaurs had a distinctive hip bone. Live Science cast any doubt on the claims: “it’s still a hypothesis […]

Dinosaur Evolution Is Relative

March 5, 2010

The science news media are all reporting that the “oldest known dinosaur relative” has been found. The artist reconstructions of Asilisaurus kongwe, found in middle Triassic layers in Tanzania, make the creature look quite dinosaurian; at least it was dog-sized and walked on thick legs under its body like its famous brethren did. Its early […]

Evolutionary Inferences: Are They Incontrovertible?

February 23, 2010

No matter what is found in plants or animals, it finds its way into an evolutionary explanation eventually. Are these explanations driven by the data, or forced into a belief system? Are other explanations possible? Some recent reports might inform these questions. Your inner plant: Get in touch with your inner plant with a report […]

Dinosaurs Evolved from Birds

February 9, 2010

Birds evolved from dinosaurs, we are often told. That’s backwards, reply some scientists at Oregon State University. According to PhysOrg, the recently-published bi-plane model study of Microraptor gui (01/29/2010) demonstrates that theropod dinosaurs did not sprout wings and fly; instead, they became flightless after their bird ancestors came down from the trees. Their […]

Incredible Creatures that Support Evolution?

January 29, 2010

Paleontologists and biologists continue to uncover animals past and present that exhibit amazing diversity. Some of them are so weird and unexpected, they are almost unbelievable. Usually, the news media are quick to tally up points for Darwin by explaining to lay people how they shed light on evolution. But in the “discovery” stage of […]

Evidence for Evolution, or for Uncontroversial Variation?

December 24, 2009

Science papers and articles often announce promising new evidence for evolution. To distinguish Darwinian evolution from creation, though, requires evidence of a certain magnitude. The staunchest Biblical creationist allows for a great deal of variation within kinds. When evidences for evolution are announced, do they rise to the level of change Darwin theorized – like […]

Darwin vs. the Fossils

December 11, 2009

What could be more iconic to evolution than dinosaurs and the horse series? Museums often display skeletons of these animals as proof of evolution. The real story told in scientific papers is often very different. Two recent studies present major, serious challenges to Darwin’s theory. Horse series: The old straight-line chart of horse evolution from […]

Dino Clawprints in the Sandstones of Time

October 6, 2009

Some of the largest dinosaur tracks ever found have been uncovered in France. The BBC News has a picture of tracks nearly 5 feet across made by sauropods that weighed 30 tonnes. Tracks of ornithischian dinosaurs in South Africa are being analyzed for clues to dinosaur behavior, reported Science Daily. The team believes that tracks […]

Anchiornis: Foot Feathers Confuse Bird Evolution Story

October 1, 2009

The paper on Anchiornis huxleyii was published in Nature,1 along with a News article about it in the same issue by Lawrence Witmer.2 In addition, popular reports were printed by the BBC News, Live Science and Science Daily. The popular reports are focusing on Xing Xu’s claim that this fossil removes the last […]

Ho-Hum, Another Feathered Dinosaur

September 25, 2009

Another Chinese fossil its discoverers are calling a “feathered dinosaur” has been announced by Nature News. It is ostensibly a more complete specimen of Anchiornis huxleyii that was announced last January (see 01/21/2009). The full paper on this specimen is to be published in Nature next week. The fossil is said to have […]

Velociraptors as Tree Climbers?

September 11, 2009

Remember those sickle-shaped claws on the feet of Velociraptor that terrified visitors in the Jurassic Park movies? New Scientist reported a radically different theory about them. They weren’t for eviscerating their prey; they were for climbing trees. Phil Manning (U of Manchester) previously showed they were insufficient for tearing dinosaur skin. Now he is suggesting […]

Dino Protein Confirmed

August 2, 2009

An independent study of bone marrow contents from a T. rex that was reported in 2007 to contain fragments of protein has confirmed the claim, reported Science Daily. Seven peptides from collagen, and apparently traces from hemoglobin, were detected. The findings are scheduled to be published in the Sept. 4 issue of Journal of Proteome […]
