Wooster’s Fossils of the Week: A bored Ordovician hardground from Ohio, and an introduction to a new paper on trace fossils and evolution

 Ordovician; US
Above is an image of a carbonate hardground (cemented seafloor) from the Upper Ordovician of Adams County, Ohio. It comes from the Bull Fork Formation and was recovered along State Route 136 north of Manchester, Ohio (Locality C/W-20). It is distinctive for two reasons: (1) the many external molds (impressions, more or less) of mollusk

The problem of air pollution in China continues to reach new heights. To combat the problem in any real way stringent regulation is needed. A new paper from Columbia University’s Earth Institute finds that this can be done without hurting job

I spent the weekend reading the new paper in Nature last week that made a lot of news. (Justin Gillis at The NY Times has an excellent summary of the paper here). If you missed it, the short version is that for the first time, researchers used a series of coupled models to produce a more realistic look at what will happen to Antarctica in the coming decades and centuries. There

A new paper in PNAS this week (that looked at sea level over the last 2700 years) has gotten quite a bit of attention by the main-stream media this week. A good summary of this paper and the implications is here from WBOC TV Reporter Tyler Butler. I work with Tyler and he is an exc. reporter, and he’s proof that you can do a  great story about climate change

Biology Letters 2016 12 20150947; DOI: 10.1098/rsbl.2015.0947. The idea that dinosaurs had unusual life histories is not new. The short, short version is that it is usually pretty straightforward to

A Holocene surface rupture in Germany

I am quite happy that our new paper has finally been published in GJI. We worked on a fault between Aachen and Cologne in Germany and found that there has been a surface rupturing earthquake less than 9000 years ago, and possibly not much older than 2500 years BP. The area is of interest also because in 1755/56 a series of damaging earthquakes hit Düren and its surroundings – these are the strongest historical events in Germany that we

The Less Wrong Metric (LWM): towards a not wholly inadequate way of quantifying the value of research

I said last time that my new paper on Better ways to evaluate research and researchers proposes a family of Less Wrong Metrics, or LWMs for short, which I think would at least be an improvement on the present ubiquitous use of impact factors and H-indexes. What is an LWM? Let me quote the paper:

My new paper in PeerJ features a new phylogenetic analysis of the Aetosauria (Archosauria: Pseudosuchia). I've added many new characters and feature all known valid aetosaur taxa. In the Supplemental Materials, each character is described and figured to clarify them for future use.   This paper also introduces a new aetosaur, Scutarx deltatylus, from the Chinle Formation of Arizona.

New Paper: Paleoseismology & active tectonics in Greece, and how seismic hazard zonation fails

We published a new study dealing with paleoseismological work on the Milesi Fault near Athens, Greece. A slip rate was estimated based on GIS work, mapping, and trenching. Four surface-rupturing earthquakes in the last 4-6 ka were found, and we estimate magnitudes of around M6.2. With these input parameters, we developed a seismic hazard scenario that also takes into account site effects. Our results show that the official seismic hazard zonation in Greece, which is based on instrumental and [...]

The Canyonlands National Park, Utah, is famous for its beautiful landscape and spectacular landforms. For many geoscientists it is also well-known as a sandstone reservoir analogue and as a tourist you’ll often run into groups of geologists on field trips. It’s a matter of debate how and how fast the beautiful grabens in the Needles Fault zone formed – these are large arcuate canyons several tens of kilometres in length, paralleling the Colorado River.

Imagine I look at a numerical weather model forecast that predicts the temp. at 5 PM the next day, will be 30C where I live. The next day, I go out at 5 PM and measure 29C instead. Was the model wrong? Probably, since models are just numerical representations of the atmosphere with some processes explicitly predicted, while other processes (like clouds) approximated from other model variables.
