Velociraptors as Tree Climbers?

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

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 […]

Dakota Dino Reveals Skin Cells

“Absolutely amazing” and “absolutely gobsmacking” are exclamations made by scientists analyzing the fossilized skin of a hadrosaur known as Dakota.  The researchers found cell structures and organic matter in the skin and layers that resemble the skin of birds and crocodiles.     The specimen was uncovered in 1999 on a North Dakota ranch and […]

We Know Less Than We Think

Strange reports come from science news outlets on occasion that call into question facts we thought we understood.  These raise a question: do we really know what we think we know? Cutting dinosaurs down to size:  Dinosaurs may have been half as heavy as thought, said Science Daily.  Some paleontologists are claiming that widely-used methods […]

Dino Fossils Generate Overblown Claims

04/10/2006), inventing feathers out of thin air.  This time, it was justified on the basis of a new paper in Nature that claims to remove an obstacle in the dinosaur-bird evolution story.1  Doubters had pointed to differences in the three forward-pointing toes.  With dinosaurs, it was toes 1, 2 and 3 that were retained; while […]

Birds Didn’t Evolve from Dinosaurs

June 9, 2009 — “The findings add to a growing body of evidence in the past two decades that challenge some of the most widely-held beliefs about animal evolution.”  That statement is not being made by creationists, but by science reporters describing work at Oregon State University that cast new doubt on the idea that […]

Dinosaur Blood Protein, Cells Recovered

It’s official: soft tissue, including blood vessel proteins and structures resembling cells, have been recovered from dinosaur bone.  Mary Schweitzer’s amazing claim in 2005 (03/24/2005) was subsequently disputed as possible contamination from biofilms (07/30/2008).  Now, Schweitzer and her team took exceptional precautions to avoid contamination by excavating hadrosaur bone from sandstone said to be 80 […]

Evolution: A Theory in Revision

Evolution is not so much a fact of nature that Darwin discovered, as it is a framework for interpreting evidence.  Within that framework are many subplots that can be overturned without falsifying the framework.  Here are some recent examples: Chicxulub loses impact:  We’ve seen the animations of a giant impact wiping out the dinosaurs.  The […]

Missing Links Found: Walking Seal, Teen Tyrannosaur

Science news media are abuzz with reports that two missing links have been found.  One is a fossil seal (pinniped) with four legs, the other a smaller presumed ancestor of the famous Tyrannosaurus rex. Seal:  National Geographic News calls it a seal with arms, and features artwork of an otter-like animal doing a kind of […]

How Valid Is Computerized Dinosaur Reconstruction?

Can you reconstruct a dinosaur on a computer?  Of course you can.  The question is how accurate it reflects something no one has ever seen.  Live Science told about Peter Falkingham at the University of Manchester who is using “genetic algorithms” and simulating evolution to figure out how dinosaurs walked.     A dinosaur’s gait […]

Tall Dinosaurs Couldn’t Lift Up Their Heads

In Jurassic Park, the huge sauropods were pictured grazing on the tops of tall trees.  This would have been physically implausible, said an Australian biologist in a letter to Science.1  A brachiosaur’s head would be 9 meters above its chest.  That would require 750 mm (Hg) of blood pressure.  The problem of circulation, not only […]

Amazing Fossils: Do They Help Darwin?

Some remarkable fossils have been found recently.  According to the reports, scientists are not sure what to make of them, even though evolutionary language is liberally applied to the interpretation. Octopus:  The earliest fossil octopus is 100% octopus.  A rare well-preserved octopus fossil, as unlikely as finding a fossilized sneeze according to Live Science, shows […]

The Early Bird Gets the Just-So Story

If a catastrophic world event wiped out the dinosaurs, why did birds survive?  They’re smaller and more delicate, it seems.  National Geographic published a new hypothesis: they out-thought the doomed dinosaurs.  “Birds survived the global catastrophe that wiped out their dinosaur relatives due to superior brainpower, a new study suggests.”     A couple of […]

Feather Evolution Proved?

Another claim of feather evolution was reported in PNAS.1  Creationists have long claimed that the evolution of feathers from reptilian scales is an intractable problem for Darwinists (example: 1994 article from Creation magazine).  Does the paper provide incontrovertible proof that feathers had evolved in dinosaurs before birds took flight in the air?     Beipiaosaurus, […]

Nature Struts Darwin Gems

Like a showcase of pearl-handled revolvers, an armory of evidences Nature calls “Darwin’s Gems” have been exhibited to warn creationists that Darwin Day will be defended next month with a show of force.  The authors, Henry Gee (former editor of Nature), Rory Howlett and Philip Campbell have made their 15 Evolutionary Gems freely available “and […]
