Fossil bone microanalyses reveal the ontogenetic histories of extinct tetrapods, but incomplete fossil records often result in small sample sets lacking statistical strength. In contrast, a histological sample of 50 tibiae of the hadrosaurid dinosaur Maiasaura peeblesorum allows predictions of annual growth and ecological interpretations based on more histologic data than any previous large sample […]

No Comments »Mass extinction led to many new species of bony fish
October 24th, 2015 Riffin With over 30,000 species worldwide, the ray fins are currently the largest group of fish. These bony fish were not always as numerous, however. Losses of other fish species, such as cartilaginous fish, helped them to spread successfully. As paleontologists from the University of Zurich together with international researchers reveal, a series of serious extinction […]

October 22nd, 2015 Riffin In the 250-million-year evolutionary history of turtles, scientists have seen nothing like the pig nose of a new species of extinct turtle discovered in Grand Staircase-Escalante National Monument by a team from the Natural History Museum of Utah. “It’s one of the weirdest turtles that ever lived,” said Joshua Lively, who described the new species […]
Spinolestes may be earliest mammal
October 19th, 2015 Riffin A recently discovered fossil of a hedgehog-like creature may push back the date at which scientists believe mammals began to appear on Earth by more than 60 million years.The 125-million-year-old fossil, which was found in Spain, has what researchers say is the “earliest record of preserved mammalian hair structures and inner organs.” The creature, which […]

October 18th, 2015 Riffin Peanut wood is a variety of petrified wood that is usually dark brown to black in color. It is recognized by its white-to-cream-color markings that are ovoid in shape and about the size of a peanut. It received its name from these peanut-size markings. It is a fossil gem with a very unusual history. How […]

October 16th, 2015 Riffin Scientists describe a perinatal group of Saurolophus angustirostris, a giant hadrosaur dinosaur, all likely from the same nest, found at “Dragon’s Tomb” in Mongolia, according to a study published October 14, 2015 in the open-access journal PLOS ONE by Leonard Dewaele from Ghent University and the Royal Belgian Institute of Natural Sciences, Belgium and colleagues.

October 14th, 2015 Riffin Scientists have used the fossilized eggshells of dinosaurs to estimate their body temperatures — and have revealed some surprises. Researchers have long debated whether dinosaurs were warm blooded like their living relatives, modern birds. In recent decades, the idea that dinosaurs — especially later, smaller, more bird-like dinosaurs – were warm blooded and active like birds, rather than more sluggish […]
Tropical ants in Europe
October 13th, 2015 Riffin Tropical ants in Europe “Imagine I could send an ecologist to Europe back tens of millions of years ago. Then, ask them to look at the ants and to tell me where they think they have landed… They would say South East Asia,” explains Prof. Evan Economo of the Okinawa Institute of Science and Technology […]

October 11th, 2015 Riffin Birds have an enormously long evolutionary history: The earliest of them, the famed Archaeopteryx, lived 150 million years ago in what is today southern Germany. However, whether these early birds were capable of flying — and if so, how well — has remained shrouded in scientific controversy. A new discovery published in the journal Scientific […]
