Latest Fossil Stories
Paleontologists can't always get what they want, to paraphrase the Rolling Stones, but sometimes they can get what they need, according to a study that will appear in the May issue of the American Naturalist.
Evidence that the first widespread occurrence of terrestrial vertebrates 300 million years ago was in response to a brief episode of a globally warmer, drier climate.
Decaying corpses are usually the domain of forensic scientists, but paleontologists have discovered that studying rotting fish sheds new light on our earliest ancestry.
How revising an ancient species can change what we know of a lineageâ€™s historical distribution and the climate in which it lived.
Scientists have confirmed that spider webs discovered in Britain are the oldest on record, dating back 140 million years to the Cretaceous period.
The fossil remains of some of the first animals with shells, ocean-dwelling creatures that measure a few centimeters in length and date to about 520 million years ago, provide a window on evolution at this time.
Known for their wide variety of vibrant plumage, birds have evolved various chemical and physical mechanisms to produce these beautiful colors over millions of years.
Paleontologists say Angola is fast becoming a "museum in the ground" for rare dinosaur fossils, where some are actually sticking out of the ground.
Early relatives of spiders that lived around 300 million years ago are revealed in new three-dimensional models, in research published today in the journal Biology Letters.
A new technique might help locate looters who stole from Utah's collection of dinosaur bones.
Leptofoenus pittfieldae is an extinct species of wasp that lived during the Miocene Burdigalian stage. It was found encased in amber from the island of Hispaniola. This species was described by studying one individual that was found in a piece of amber, mined by the La Toca mine group in the Dominican Republic. Although amber is abundantly mined in that area, no other individuals of this species have been found. The specimen is now located in the University of Kansas Natural History Museum in...
Atrypa (lampshell) is an extinct genus of brachiopod from the Late Ordovician stage (444 million years ago) to the Carboniferous stage (318 mya). It occurs abundantly as fossils in marine rocks. Fossils have been found on all continents except Antarctica. This animal has distinctive concentric growth lines and is unusual in that in some Devonian beds there are numerous remains of the pedicle (foot) valve, but very few of the brachial (upper) valve -- scientists speculate that strong ocean...
Seitaad, derived from a Navajo legend of a san monster with the same name -- "Seit'aad," is a genus of prosauropod dinosaur from the Early Jurassic Period. The type species, S. ruessi, was described in 2010 based on fossils recovered from the Navajo Sandstone Formation in southern Utah. It is known from a nearly complete fossil that appears to have been entombed by the collapse of a sand dune about 185 million years ago. Based on the fossil, the dinosaur would have been 10 to 15 feet long...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
