Another great video, but I did think it was weird that in the part where they were talking about other scientists finding fault with Dr. Mary Schweitzer's work that that is their job. She has said she would be disappointed if people didn't try and falsify her hypothesis.

One pretty funny thing about the Prasad et al. paper (in terms of creationists using it as a gotcha) on the early evolution of grasses is that it confirmed predictions made by molecular phylogenies (such as Janssen & Bremer, 2004) that estimated the diversification of modern grass clades began approximately 83 million years ago. Any "win" on the creation side from this discovery is dwarfed by the fact that this is another example of where the molecular dates seemed to conflict with the fossil dates until the fossils were found to be exactly where they were predicted to be (in time at least, and more roughly in location).
