This page is about what I encounter within the realm of the geosciences, as well as the occasional rant about nonsense. I tend to focus primarily on stratigraphy and sedimentology, but occasionally branch out into related fields.
Yesterday was a good day. I turned in the final draft of my thesis before my defense, I went to the local bar with some friends, and I generally had a pleasant evening reading popular fiction. Then I checked my email around 10:30 pm. My advisor sent me an article pertaining to my general research area. He is underwhelmed and said the article was "hot" off the presses. My mood was deflated and, reading the author list, I thought this group admitting uncertainty about the bolide impact extinction ........ Read more »

Sergio Mora published a paper in the Journal of the Geological Society (here subscription is required for full text*). This was published back in December 2009, but it took on new (and rather unfortunate) significance in Haiti recently. It is really an excellent paper, he presented something similar as the keynote speaker at the 1st North American Landslide Conference in Vail, CO 2007. My summary doesn't do the paper justice, so I strongly suggest anyone reading this post find a copy of this art........ Read more »

Have you ever had one of those moments, where you read a paper, and you realize the paper is saying...pretty much everything you have been working on for the past few seasons. Fortunately, in this case, the paper's location is on the opposite side of the world and approximately 190 Ma earlier. So I think I am safe. *Phew*The paper in question is Gastaldo et al, 2009 (availble here). This was published in the March issue of Geology, which means you will have to meander over to your local library/........ Read more »
