Winners of Mass Extinction: With Predators Gone In modern ecology, the removal or addition of a predator to an ecosystem can produce dramatic changes in the population of prey species. For the first time, scientists have observed the same dynamics in the fossil record, thanks to a mass extinction that decimated ocean life 360 million [...]
Paleontologists Audition Modern Examples of Ancient Behavior Paleontologists agree that it’s difficult to observe behavior in fossil specimens that are dead — even extinct — and petrified. One method is to find a modern, living, species that has some similarities to the ancient animal. That’s the strategy adopted by David L. Meyer, University of Cincinnati [...]
Historic Church’s Subterranean Secrets Revealed Researchers from Kingston University in London have carried out a full scientific survey of an historic churchyard widely believed to be the site of the crowning of at least two Anglo-Saxon kings. The team used an earth resistance meter to survey a graveyard at the site where possibly as many [...]
Jurassic Spider from China Is Largest Fossil Specimen Discovered With a leg span of more than five inches, a recently named Jurassic period spider from China is the largest fossil specimen discovered, and one that has modern relatives in tropical climates today. A research team of KU and Capital Normal University (Beijing) researchers said the [...]
Melting Ice on Arctic Islands a Major Player in Sea Level Rise Melting glaciers and ice caps on Canadian Arctic islands play a much greater role in sea level rise than scientists previously thought, according to a new study led by a University of Michigan researcher. The 550,000-square-mile Canadian Arctic Archipelago contains some 30,000 islands. [...]
Infection in Jaw of Ancient Reptilian Fossil Revealed A reptile that lived 275-million years ago in what is now Oklahoma is giving paleontologists a glimpse of the oldest known toothache. Led by Professor Robert Reisz, the chair of the Department of Biology at the University of Toronto Mississauga, scientists found evidence of bone damage due [...]
Long-Sought Fossil Mammal With Transitional Middle Ear Paleontologists from the American Museum of Natural History and the Chinese Academy of Sciences announce the discovery of Liaoconodon hui, a complete fossil mammal from the Mesozoic found in China that includes the long-sought transitional middle ear. The specimen shows the bones associated with hearing in mammals — [...]
Loch Fossils Show Life Harnessed Sun and Sex Early on Remote lochs along the west coast of Scotland are turning up new evidence about the origins of life on land. A team of scientists from the University of Sheffield, the University of Oxford and Boston College, who are exploring rocks around Loch Torridon, have discovered [...]
Fossils: Clues for Predicting Climate Change By studying fossilized mollusks from some 3.5 million years ago, UCLA geoscientists and colleagues have been able to construct an ancient climate record that holds clues about the long-term effects of Earth’s current levels of atmospheric carbon dioxide, a key contributor to global climate change. Two novel geochemical techniques [...]
Fossil Teeth Show What African Animals Ate Fossil teeth of African animals show that during the past 10 million years, different plant-eating critters began grazing on grass at different times as many switched from a salad-bar diet of tree leaves and shrubs, says a University of Utah study. The first animals to hit the hay [...]
