Argentinosaurus is a genus of titanosaur sauropod dinosaur first discovered by Guillermo Heredia in Argentina. The generic name refers to the country in which it was discovered. The dinosaur lived on the then-island continent of South America somewhere between 97 and 94 million years ago, during the Late Cretaceous Epoch. Reconstructed skeleton of Argentinosaurus huinculensis at […]

Dinosaurian Soft Tissues Interpreted as Bacterial Biofilms: Research by Thomas G. Kaye , Gary Gaugler, Zbigniew Sawlowicz
March 2nd, 2013 
Riffin A scanning electron microscope survey was initiated to determine if the previously reported findings of “dinosaurian soft tissues” could be identified in situ within the bones. The results obtained allowed a reinterpretation of the formation and preservation of several types of these “tissues” and their content. Mineralized and non-mineralized coatings were found extensively in the […]
Feeding Limbs and Nervous System of One of Earth’s Earliest Animals Discovered
March 1st, 2013 Riffin An extraordinary find allowing scientists to see through the head of the ‘fuxianhuiid’ arthropod has revealed one of the earliest evolutionary examples of limbs used for feeding, along with the oldest nervous system to stretch beyond the head in fossil record. Until now, all fossils found of this extremely early soft-bodied animal featured heads covered […]
A New Non-Pterodactyloid Pterosaur from the Late Jurassic of Southern Germany
February 25th, 2013 Riffin The ‘Solnhofen Limestone’ beds of the Southern Franconian Alb, Bavaria, southern Germany, have for centuries yielded important pterosaur specimens, most notably of the genera Pterodactylus and Rhamphorhynchus. Here we describe a new genus of non-pterodactyloid pterosaur based on an extremely well preserved fossil of a young juvenile: Bellubrunnus rothgaengeri (gen. et sp. nov.). Methodology/Principal Findings […]
Stratigraphy and the Principles of Relative Dating
February 23rd, 2013 Riffin Relative dating falls under the sub-discipline of geology known as stratigraphy. Stratigraphy is the science of rock strata, or layers. Layering occurs in sedimentary rocks as they accumulate through time, so rock layers hold the key to deciphering the succession of historical events in Earth’s past. The fundamental principles of stratigraphy are deceptively simple and […]

No Comments »Living” molecules found in fossil
February 22nd, 2013 Riffin “Living” molecules, meaning intact cellular structures that haven’t fossilized, were recently retrieved from 350-million-year-old remains of aquatic sea creatures uncovered in Ohio, Indiana, and Iowa, according to a study that will appear in the March issue of the journal Geology. The animals- crinoids– were spindly and had feathered arms. Their relatives today are called by […]
First Known Feeding Trace of the Eocene Bottom-Dwelling Fish Notogoneus osculus and Its Paleontological Significance
February 21st, 2013 Riffin Background The Green River Formation (early Eocene, about 42–53 Ma) at and near Fossil Butte National Monument in Wyoming, USA, is world famous for its exquisitely preserved freshwater teleost fish in the former Fossil Lake. Nonetheless, trace fossils attributed to fish interacting with the lake bottom are apparently rare, and have not been associated directly […]
Fossil from China Cast Evolution in New Light
February 21st, 2013 Riffin Strange fossils, including some that could be predecessors to modern animals, found in China shed new light on the evolution of large, complex organisms, and indicate that they may have diversified earlier than thought. Researchers believe that the rocks containing these fossils, found in southern Anhui Provence, date between 635 million and 580 million years […]
