The dry, barren prairie around Alberta’s Drumheller area was once a lush and subtropical forest on the shores of a large inland sea, with loads of wetlands inhabited by dinosaurs, turtles, crocodiles and small mammals. But that changed about 71-million-years ago, according to a new study by researchers Annie Quinney and Darla Zelenitsky in paleontology […]

March 15th, 2013 Riffin A new fossil leaf impression of Alphonsea Hk. f. & T. of the family Annonaceae is described from the Late Oligocene sediments of Makum Coalfield, Assam, India. This is the first authentic record of the fossil of Alphonsea from the Tertiary rocks of South Asia. The Late Oligocene was the time of the last significant […]

March 14th, 2013 Riffin University of Georgia researchers discovered important genetic clues about the history of microorganisms called archaea and the origins of life itself in the first ever study of its kind. Results of their study shed light on one of Earth’s oldest life forms. “Archaea are an ancient form of microorganisms, so everything we can learn about […]
Cryptic Clams: Biologists Find Species Hiding in Plain View
March 14th, 2013 Riffin Cryptic comments seem to have an ambiguous, obscure or hidden meaning. In biology, cryptic species are outwardly indistinguishable groups whose differences are hidden inside their genes. Two University of Michigan marine biologists have identified three cryptic species of tiny clams, long believed to be members of the same species, which have been hiding in plain […]

March 13th, 2013 Riffin A study headed by the Miquel Crusafont Catalan Palaeontology Institute has for the first time documented detailed records of dinosaur egg fossils in the Coll de Nargó archaeological site in Lleida, Spain. Up until now, only one type of dinosaur egg had been documented in the region. The archaeological site in Coll de Nargó containing […]
Secondary Cartilage Revealed in a Non-Avian Dinosaur Embryo
March 12th, 2013 Riffin The skull and jaws of extant birds possess secondary cartilage, a tissue that arises after bone formation during embryonic development at articulations, ligamentous and muscular insertions. Using histological analysis, we discovered secondary cartilage in a non-avian dinosaur embryo, Hypacrosaurus stebingeri (Ornithischia, Lambeosaurinae). This finding extends our previous report of secondary cartilage in post-hatching specimens of […]
Species Concepts in Paleontology
March 11th, 2013 Riffin I. Various Species Concepts A. Determining whether two plants are members of the same species has intriqued and perplexed biologists for a very long time. Indeed, some question the reality of species from a philosophical standpoint, such as nominalism and realism (see Wikipedia for discussion of this as well as definitions of species). Darwin said […]

March 9th, 2013 Riffin Dr. Robert T. Bakker is one of palaeontology greatest and most well known characters. Bakker was the first man who hypothesized that dinosaurs may have been warm-blooded, and was the scientist who believed that diseases caused the demise of the terrible lizards. He is also the author of the famous book The Dinosaur Heresies. Bakker […]

March 9th, 2013 Riffin The carnivorous Tyrannosauridae are among the most iconic dinosaurs: typified by large body size, tiny forelimbs, and massive robust skulls with laterally thickened teeth. The recently described small-bodied tyrannosaurid Raptorex kreigsteini is exceptional as its discovery proposes that many of the distinctive anatomical traits of derived tyrannosaurids were acquired in the Early Cretaceous, before the […]
