Cowen et al. (2025) study the geochemistry of dental tissue of Devonian fish fossils from Svalbard and Cretaceous lungfish and plesiosaur fossils from Australia, and interpret their findings as indicative of preservation of the primary chemical composition of the bioapatite in the studied fossils. [61] Albert et al. (2025) provide new ...
New specimen of Archaeopteryx, representing the third specimen belonging to this genus found in the Tithonian Mörnsheim Formation , is described by Foth et al. (2025). [ 60 ] Evidence from the study of moa coprolites , indicating that moa ate and likely spread truffle-like fungi that are endemic to New Zealand , is presented by Boast et al ...
"The sale of Sue was a turning point, I think, [for] the commercial sale of fossils," Spencer Lucas, a curator of paleontology at the New Mexico Museum of Natural History and Science in ...
A rare dinosaur bone bed containing 115-million-year-old fossils has been unearthed in Maryland, officials and experts say. During a dig at Prince George’s County’s Dinosaur Park in Laurel in ...
The private sale of fossils has attracted criticism from paleontologists, as it presents an obstacle to fossils being publicly accessible to research. [2] Most countries where relatively complete dinosaur specimens are commonly found have laws against the export of fossils. The United States allows the sale of specimens collected on private ...
The fossil examined in the study, collected during a 2011 expedition by the Antarctic Peninsula Paleontology Project, was found encased in rock that dated back 68.4 to 69.2 million years and ...
Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed.
Measuring about 10 metres long, it is one of the largest known land-based carnivores ever to have roamed the Earth – comparable in size to the slightly younger Tyrannosaurus rex from North America.
