T. rex Trouble

By Carl Zimmer | August 25, 2008 12:43 pm

A couple weeks ago I blogged on a debate over the discovery of soft tissue in a dinosaur. Over at Nature, Rex Dalton has a spicy article about a fresh assault on the findings. I wrote about how the alleged blood vessels and cells in a T. rex fossil might be bacterial biofilms. The scientists had also isolated what they proposed was collagen from the same fossils. Now critics are calling that study “computationally illiterate.” Zing–!

    I’d like to point out that this is isn’t the first reply (in opposition) to the recent dino DNA/protein work, nor is it the first dino DNA study to be criticized by the scientific community. Indeed, such antics have been captivating the field since the early 1990s, when “ancient DNA” was at its innocent beginnings…

    and some older stuff:
