We had a weekend in the Big Apple.  It was our big Asmis family reunion, 31 people including lots of little kids. Our branch stayed in this great airb&b brownstone walk-up that was all redone and had two levels.  Very economical for 6 people.  It was right in the middle of the resurgent Harlem.  Very nice.  We ended up walking about 20 miles according to the fitbit.

Orthospirifer sp. brachiopod from the Silica Shale

Years ago I purchased some brachiopods that came from the middle Devonian aged Silica Shale in Ohio. These were fossils that had been collected in the 80's and 90's and came from older collections. Among the various species were these two articulated shells. The label that came with them called them Orthospirifer sp. but they look very similar to Mediospirifer audaculus which is a somewhat common brachiopod species from the middle Devonian. I've done a little research and it seems to me that [...]

I have said it to countless people over the last 36 years: Put as many walls between you and the outside as possible if a tornado is approaching, and if there is a bathroom in the middle of the house, that’s the place to go. The photo above was taken by one of the storm survey teams from the NWS in Norman,OK today and the young man in the picture

I could have made up a detailed geological description of the geology of this alluvial plain at the south end of the Death Valley graben. This is a geology blog, after all. But we were there in the middle of February during the most extraordinary flower show, a "superbloom", in a decade. A series of fall storms were spaced just well enough to wake up the myriads of seeds that hide in the

We’ve arrived at site 4, and are making great progress, recovering about 40 metres of sediment an hour! Though this site seems relatively easy to core, it presents two interesting challenges. First, the sediment so far has a VERY strong smell of rotten eggs. Secondly, we’re drilling right in the middle of the Carnarvon Basin, the most productive petroleum field in Australia. This makes things tricky. read

The National Weather Service is warning that heavy rains are expected to cause flooding on Havasu Creek and flood campsites and foot bridges. This time of year there can be hundreds of campers in the campgrounds in the scenic canyon on the Havasu Reservation just south of the Grand Canyon.  In 2006, flash floods forced ~400 campers to flee to high ground in the middle of the

This specimen, that I collected from the Kalkberg formation of New York, has given me some trouble trying to identify it but I think I've narrowed it down to Machaeraria formosa. I'm basing this due to the description by Hall in "Paleontology of New York", Vol III part 1, page 236:SHELL subtriangular or transversely oval; lateral margins forming an angle at the beak of about 90° to 110°. Ventral valve somewhat more depressed than the opposite: beak prominent, arched, not strongly incurved. [...]

New species from Ethiopia further expands Middle Pliocene hominin diversity. 2015. Nature. Australopithecus deyiremeda is a new 3.3 to 3.5 million-year-old human ancestor. Its upper and lower jaw fossils were recovered from the Woranso-Mille area of the Afar region of Ethiopia. This hominin lived alongside the famous “Lucy’s” species, Australopithecus afarensis.

Two important new palaeobiological hypotheses regarding diplodocids 

Sauropod Vertebra Picture of the Week [2015-05-14 12:12:47]  recommend  recommend this post  (120 visits) info
The first hypothesis is that, contra Elk (1972), all Brontosauruses were rather fat at one end, then much fatter in the middle, then thin at the other end. The second theory is that Diplodocus was dumb. Evidence is here presented in the form of an important new life restoration by Matthew Taylor. References Elk, Anne.

On this expedition, we’re studying sediments that have been eroded from the Himalayas, the highest mountain range in the world. The Ganges and Brahmaputra rivers carry this sediment to the delta in Bangladesh, but what happens next? How does this material get all the way out to the middle of the Bay of Bengal where we’re drilling, almost 2,000 kilometers (1,243 miles)

We’re in the Indian Ocean currently drilling the deepest of a six hole transect across the middle of the Bengal submarine fan. The fan covers the bottom of the Bay of Bengal with sediments eroded from the Himalayas. We’ll be devoting almost three weeks of our eight-week International Ocean Discovery Program expedition to drilling at this site. Our target: to reach 1,500 meters (about a mile) depth. Drilling this deep is a major challenge when you are drilling into the seafloor, which just [...]
