A study of life and extinctions among woolly mammoths and other ice-age animals suggests that interconnected habitats can help Arctic mammal species survive environmental changes. The study went online Nov. 2 in the Proceedings of the National Academy of Sciences “Early Edition.” Short periods of warm climate in the midst
Archaeologists with The Australian National University (ANU) have discovered fossils of seven giant rat species on East Timor, with the largest up to 10 times the size of modern rats. Dr Julien Louys of the ANU School of Culture, History and Language, who is helping lead the project said these
At the 2015 Society of Vertebrate Paleontology meetings, researcher Michael Cherney of the University of Michigan, presented findings about weaning age (i.e. when a calf stops nursing) in fossil mammoths.
It is currently believed that great apes, including humans, diverged from small-bodied apes roughly 17 million years ago, but analysis of a younger fossil that has features of both groups may reshape our understanding of this evolutionary path.
An emergent field of research in dinosaur paleobiology investigates the relative importance of linear, non-branching evolution (anagenesis) compared with branching evolution (cladogenesis).
Previously, giant sharks had only been recovered from rock dating back 130 million years, during the age of the dinosaurs.
Fossils of the elasmosaur Aristonectes were first reported from the Late Cretaceous of Patagonia in 1941.
One associated effect of being ‘warm-blooded’ is a relatively fast growth-rate. Mammals (and birds, who are also ‘warm-blooded’) tend to grow much faster than ‘cold-blooded’ vertebrates, like fish and reptiles.
A nasty little 66-million-year-old family secret has been leaked by a recently unearthed tyrannosaur bone. The bone has peculiar teeth marks that strongly suggest it was gnawed by another tyrannosaur.
Nearly 100 fossil species pulled from a flooded cave in the Bahamas reveal a true story of persistence against all odds — at least until the time humans stepped foot on the islands.
Researchers know dinosaurs once ruled the earth, but they know very little about how these animals performed the basic task of balancing their energy intake and output–how their metabolisms worked.
Chemical clues about weaning age embedded in the tusks of juvenile Siberian woolly mammoths suggest that hunting, rather than climate change, was the primary cause of the elephant-like animal’s extinction.
Found with associated shell fragments, Saurolophus dino likely from nest, in earliest stages of development.
An international team of researchers, together with participation from the University of Bonn, has investigated a stunning fossil finding from the Cretaceous period.
Were dinosaurs really fast, aggressive hunters like the ones depicted in the movie “Jurassic World”? Or did they have lower metabolic rates that made them move more like today’s alligators and crocodiles?
A 48 million year-old horse-like equoid fetus has been discovered at the Messel pit near Frankfurt, Germany according to a study published October 7, 2015 in the open-access journal PLOS ONE.
The identification of a new species belonging to the marine mammal group Desmostylia has intensified the rare animal’s brief mysterious journey through prehistoric time, finds a new study.
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.
A team of University of Michigan paleontologists were able to recover about 20 percent of the animal’s bones, including the skull and two tusks, numerous vertebrae and ribs, the pelvis and both shoulder blades.
A new analysis of the fossil record by paleontologists at the University of Connecticut and the Smithsonian Institute demonstrates that the number of animal species in the world’s oceans has skyrocketed during the past 200 million years, despite mass extinctions like the one at the end of the Cretaceous Period (66 million years ago).
The coelacanth fish, found today in the Indian Ocean, is often called a ‘living fossil’ because its last ancestors existed about 70 million years ago and it has survived into the present – but without leaving any fossil remains younger than that time.
Decades of research on Montana’s state fossil — the “good mother lizard” Maiasaurapeeblesorum – has resulted in the most detailed life history of any dinosaur known and created a model to which all other dinosaurs can be compared, according to new research published recently in the journal Paleobiology.
