Latest Fossil Stories
A recent study by researchers at the University of Bath and Londonâ€™s Natural History Museum has found that scientistsâ€™ knowledge of the evolution of dinosaurs is remarkably complete.
The evolutionary history of diatoms -- abundant oceanic plankton that remove billions of tons of carbon dioxide from the air each year -- needs to be rewritten, according to a new Cornell study. The findings suggest that after a sudden rise in species numbers, diatoms abruptly declined about 33 million years ago -- trends that coincided with severe global cooling.
Earth's creatures come in all sizes, yet they (and we) all sprang from the same single-celled organisms that first populated the planet.
While paleontologists may scour remote, exotic places in search of prehistoric specimens, Tufts researchers have found what they believe to be the world's oldest whole-body fossil impression of a flying insect in a wooded field behind a strip mall in North Attleboro, Mass.
An analysis of the gut contents from an exceptionally well-preserved juvenile dinosaur fossil suggests that the hadrosaur's last meal included plenty of well-chewed leaves digested into tiny bits.
By Perkins, Sid New study questions analyses of T. rex remains Three years ago, a team of scientists rocked the paleontology world by reporting the recovery of flexible tissue resembling blood vessels from a 68- million-year-old dinosaur fossil.
Massive fossil forests dating back millions of years have been found in Illinois coal mines, a British researcher says. Howard Falcon-Lang told the British Association Science Festival in Liverpool the fossil forests are the largest ever found, the BBC reported Tuesday.
To the editor: In a Wednesday editorial, you responded to my proposal for the creation of a State Paleontologist by asking: "How did this great state survive so long without one?" My answer: Very poorly.
By Molly Collins dupageneighbor@@dailyherald.com As this winter drags on, it is hard to picture the Chicago area without any snow, but 300 million years ago that was the case. Illinois actually used to be a wetland located near the equator.
Most of us think fossils are fascinating evidence of life in the past, eons before the first person appeared. People are usually captivated by the large fossils - dinosaurs, mammals and sharks - but only a few ever look at the microfossils.
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...
