evolutionites grasping at straws as usual....

Doing science, as usual. Science doesn't mind correcting errors. With each error corrected, science becomes more accurate.

But those poor creationists, who focused on this as proof positive of a young earth are sobbing in their beers.

For one thing, says Schweitzer, she and her team dismissed bacterial biofilms as a possible cause of the tissues she and her team observed. Such coatings probably would be thicker along the lower surfaces of the vascular spaces, but the flexible structures that her team recovered had walls with an even thickness. Also, she notes, there’s no reported evidence that biofilms can produce branching, hollow tubes like those noted in her study.

The material purported to be T. rex collagen in the Schweitzer study had the appropriate microscopic structure. Tests also revealed the material’s similarities, such as its ratio of glycine and alanine, to chicken collagen. These results bolster the notion that dinosaurs are related to modern birds, Schweitzer and her colleagues reported.

Furthermore, says John M. Asara, an analytical chemist at Harvard Medical School in Boston and a colleague of Schweitzer, the type of collagen found was bone-specific and isn’t a common protein contaminant.

Schweitzer sounds more convincing to me.
