Your guess is as good as mine when it comes to identifying the predator that left its undeniable marks on this prehistoric morsel.  This discovery came in September 2014 in the panhandle of Florida.   At first glance, it appeared to be just an ordinary fossil rock but upon closer inspection, it was obvious, this was

While exploring an old coal strip mine in Gilberton, PA I noticed that there was an exposed wall of rock that used to be covered in overburden. The wall was relatively smooth but had some grooves in it. Upon closer inspection, the grooves turned out to be the impressions of tree roots called Stigmaria. Since these are roots, and they appear to have been preserved in situ, makes me think that the exposed rock is a Paleosol or fossil soil horizon.I encourage you to click on the photos to [...]

PRISM and TEMPORA: Greg’s cable map shows worldwide undersea communication infrastructure

In these days PRISM and TEMPORA are the keywords in global media. United States and Great Britain are two of the (western) global-players which are monitoring global communication infrastructure. But how they can get access to all this data flows? They are physically connected to different undersea communication cables. On closer inspection you can see

A final airing for Jane Burton's glorious photographs, with a little 1980s nuttiness along the way! In case you've missed them, check out part 1 and part 2, too.While this book is really all about the photography (of course), there are a small number of illustrations in the opening chapter which, to be honest, aren't really much to write home about. However, at least one is amusing in that it appears to be a lesson in the science of reconstructing extinct animals, as intended for pre-Dino [...]

One of the hidden geologic gems located just east of the Colorado Plateau and the Rio Grande Rift is the Great Sand Dunes National Park and Preserve. In July, I approached this interesting area with colleague Jack Share while traveling from Durango, to the Continental Divide at Wolf Creek Pass, and across the Alamosa Valley located in the floor of the rift. It is a beautiful and interesting place.The Sangre de Cristo Mountains loom behind the dunes. This view is to the northeast and behind us [...]

On my trips up to Canada I make a point to get up to the Brechin area and visit the Ordovician aged rock quarries. On one such trip I found the piece below which is rife with a Monoplacophoran called Archinacella patelliformis. Monoplacophorans (latin for "bearing one plate") are gastropod like mollusks which have a cap shaped shell rather than a spiral shape. They are considered very primitive and there is thought that they are representative of the original ancestor of all mollusks.Upon a [...]
