Paleontology & Fossils

A study led by scientists at the American Museum of Natural History has resolved a long-standing controversy about an extinct "horned" crocodile that likely lived among humans in Madagascar. Based on ancient DNA, the research shows that the horned...
Paleontologists have discovered two new species of mammal-like, burrowing animals that lived about 120 million years ago in what is now northeastern China. The new species, described today in the journal Nature, are distantly related but independently evolved traits to...
A well-preserved female land snail fossilized in Cretaceous amber shortly after the birth of her offspring was discovered in Myanmar. The discovery offers unprecedented insights into the ecology and behavior of snails that lived 99 million years ago. Land snails...
Woolly mammoths may have walked the landscape at the same time as the earliest humans in what is now New England, according to a Dartmouth study published in Boreas. Through the radiocarbon dating of a rib fragment from the Mount...
The fearsome tyrannosaur dinosaurs that ruled the northern hemisphere during the Late Cretaceous period (66-100 million years ago) may not have been solitary predators as popularly envisioned, but social carnivores similar to wolves, according to a new study. The finding,...
The new dinosaur species, Tlatolophus galorum is herbivorous dinosaur from 73 million years ago that emitted strong sounds. Excavations in Mexico reveal an intact fossil of a so-called peaceful but talkative dinosaur. The animal crest's shape looks like "a...
Research on a newly discovered bird fossil led by The University of Texas at Austin found that a unique brain shape may be why the ancestors of living birds survived the mass extinction that claimed all other known dinosaurs. Today,...
An 18.5 million-year-old fossil found in Panama provides evidence of a new species and is the oldest reliable example of a climbing woody vine known as a liana from the soapberry family. The discovery sheds light on the evolution...
A newly described horned dinosaur that lived in New Mexico 82 million years ago is one of the earliest known ceratopsid species, a group known as horned or frilled dinosaurs. Researchers reported their find in a publication in the...
An international team of paleontologists has identified a new genus and species of hadrosaur or duck-billed dinosaur, Yamatosaurus izanagii, on one of Japan's southern islands. The fossilized discovery yields new information about hadrosaur migration, suggesting that the herbivors migrated from...
The first photosynthetic oxygen-producing organisms on Earth were cyanobacteria. Their evolution dramatically changed the Earth allowing oxygen to accumulate into the atmosphere for the first time and further allowing the evolution of oxygen-utilizing organisms including eukaryotes. Eukaryotes include animals,...
