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–!
