A previously undiscovered species of an extinct primordial giant worm with terrifying snapping jaws has been identified by an international team of scientists.
Last year, headlines in The New York Times, The Atlantic, Scientific American and other outlets declared that a decades-old paleontological mystery had been solved. The 'Tully monster,' an ancient animal that had long defied classification, was in fact a vertebrate, two groups of scientists claimed. Specifically, it seemed to be a type of fish called a lamprey. The problem with this resolution? According to a group of paleobiologists led by the University of Pennsylvania's Lauren Sallan, it's plain wrong.
California sardine stocks famously crashed in John Steinbeck's 'Cannery Row.' New research, building on the pioneering work of Soutar and Isaacs in the late 1960s and others, shows in greater detail that such forage fish stocks have undergone boom-bust cycles for centuries, with at least three species off the US West Coast repeatedly experiencing steep population increases followed by declines long before commercial fishing began.
A small crocodyliform dinosaur discovered in Germany's Langenberg Quarry may be a new species, according to a study published Feb. 15, 2017 in the open-access journal PLOS ONE by Daniela Schwarz from Leibniz Institute for Evolutionary and Biodiversity Research, Germany, and colleagues.
A remarkable 250-million-year-old 'terrible-headed lizard' fossil found in China shows an embryo inside the mother -- clear evidence for live birth. Head of The University of Queensland's School of Earth and Environmental Sciences and co-author Professor Jonathan Aitchison said the fossil unexpectedly provided the first evidence for live birth in an animal group previously thought to exclusively lay eggs.
The first ever evidence of live birth in an animal group previously thought to lay eggs exclusively has been discovered by an international team of scientists, including a palaeontologist from the University of Bristol.
The fossil of the Euchambersia therapsid (a pre-mammalian reptile), that lived in South Africa about 260 million years ago, is the first evidence of the oldest mammal to produce venom.
Scientists at Tokyo Institute of Technology uncover a sulfide-responsive protein that helps control photosynthesis in the purple bacterium Rhodobacter capsulatus.
Changing environments and ecosystems were driving the evolution of horses over the past 20 million years. This is the main conclusion of a new study published in Science by a team of paleontologists from Spain and Argentina. The team analyzed 140 species of horses, most of them extinct, synthesizing decades of research on the fossil history of this popular group of mammals.
The world is changing too fast for nature to keep up. Conservation scholars, including those at Stanford, agree that strategies need to evolve to consider not only how ecosystems operated in past decades and centuries, but also thousands and millions of years ago.
