The Museum of Nature & Science in Dallas is currently running an exhibit called "Chinasaurs" that features dinosaur fossils discovered in China. Some of these fossils supposedly represent transitional species from dinosaurs to birds. But these "feathered dinosaurs" appear to be missing a key feature…namely, the feathers.

Archaeopteryx has long been hailed as a "missing link" between birds and dinosaurs. After a recent analysis of a different fossilized creature, however, Chinese researchers concluded that Archaeopteryx was not the first bird to have evolved, but was instead more like a dinosaur. This new categorization aptly illustrates the unreliability of evolutionary tree analyses.

The famous Confuciusornis sanctus fossil from China's northeast Liaoning Province contains patches that appear to be residue from the bird's original tissues. Long evolutionary ages should have made this impossible, since any such biological material would have completely decayed into the tiniest of its constituent chemicals millions of years ago.

A Cambrian rock layer is considered to be "Cambrian" because of the particular fossils it contains. But what does it mean when a rock layer designated as "Ordovician" contains distinctly Cambrian fossils? Paleontologists are facing that question after a recent find in North Africa.

According to evolution, dinosaurs lived during an age when birds and non-reptile land creatures were either present in just a few "primitive" forms or not at all. But a recent National Geographic online interview offered a summary of fossil discoveries made in a dinosaur-bearing deposit in Madagascar.
