Wooster’s Fossil of the Week: A mystery fossil for my Invertebrate Paleontology students 

Wooster Geologists [2015-09-04 06:07:13]  recommend  recommend this post  (187 visits) info
At the beginning of my Invertebrate Paleontology course I give each student a fossil to identify by whatever means necessary. I challenge them to take it down to the species level, and tell me its age and likely place of collection. The fossil this year is shown above: the rugose coral Stereolasma rectum (Hall, 1843)

Hallucigenia’s head and the pharyngeal armature of early ecdysozoans. 2015. Nature Illo by Danielle Dufualt Abstract: The molecularly defined clade Ecdysozoa comprises the panarthropods (Euarthropoda, Onychophora and Tardigrada) and the cycloneuralian worms (Nematoda, Nematomorpha, Priapulida, Loricifera and Kinorhyncha). These disparate phyla are united by their means of moulting, but

Twitter logos for conference talks

Recently, there was a pretty massive discussion about the practice of live-tweeting at conference talk hosted on this blog. While the discussion is by no means over, or particularly conclusive, one idea to emerge was having an icon of some sort on slides during talks to indicate whether or not they could be live-tweeted. Sarah Werning has been kind enough to create and share some logos following this, and I strongly encourage academics to use these when presenting to avoid any future confusion [...]

My Greatest Adventure #68 From Today In Science History: In 1859, The Origin of Species by Means of Natural Selection was published in England to great acclaim. In this groundbreaking book by British naturalist Charles Darwin, he argued that species are the result of a gradual biological evolution in which nature encourages, through natural selection, the propagation of those species

On the first day of the Invertebrate Paleontology course at Wooster, I give all the students a fossil to identify as best they can. Everyone gets the same kind of specimen, and they can use any means to put as specific a name on it as possible. Most students struggle with the exercise, of course

Reading my tweets can be somehow interesting: It seems like ESRI invented and exclusively owns the phrase “story map”: #storymap Tweets What IS a story map? To me a story map is the same like a map: a way of information distribution. According to ESRI: “Story maps use geography as a means of organizing and presenting information. They tell the story of a place, event, issue, trend, or pattern in a geographic context. They combine interactive maps with other rich [...]

Photoshop as a means of reconstructing fault offset

I saw this fault in Texas, north of the laccolith known as Cristo Rey: Click to enlarge I had a hard time making sense of the offset in my head, though, since the layers were of inconsistent thickness. Several people tried to convince me that the offset was “normal” (that is, right side down), but it still didn’t “click” for me in the field. So I took a photo. Back

There is only one Geological Society, the one in London that was founded in 1807. Its highest award is the Wollaston Medal, which goes to "geologists who have had a significant influence by means of a substantial body of excellent research in either or both 'pure' and 'applied' aspects of the science." Willliam Hyde Wollaston (1766–1828) is also honored in the name of the pyroxene mineral wollastonite; he was also the discoverer of the precious metal palladium, the same metal that [...]

Geosciences column: Using tall trees to tot up tropical carbon

Forests in the tropics account for about half the above-ground carbon on Earth and as the trees grow older they are capable of storing more and more. In fact, their carbon-storing potential is so large that they are increasingly being viewed as a means of mitigating climate change. Take, for example, the United Nations effort to

As I was cleaning up some material that I'd found at the Penn Dixie site in Blasdell, NY, I noticed the below specimen. It appears to be a pair of Eridophyllum subcaespitosum corals that are showing the budding habit common to this species as a means of asexually reproducing (also called gemmation). The upper portions of the corals are missing but you can see the connection between the individual corallites.Interesting to note is that the left most corallite budded twice at the same level [...]
