Scientists assess how large dinosaurs could really get

Science Daily - Paleontology - Wed, 07/24/2024 - 11:30
A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests.

Jurassic fossils show modern mammals grow faster than ancient ones

New Scientist - Wed, 07/24/2024 - 11:00
The 166-million-year-old fossils of an adult and a juvenile of the same extinct mammal species reveal that they had longer "childhoods" and lifespans than similar species today

Taco-shaped arthropod fossils gives new insights into the history of the first mandibulates

Science Daily - Paleontology - Tue, 07/23/2024 - 19:47
Palaeontologists are helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.

Nanoscopic imaging aids in understanding protein, tissue preservation in ancient bones

Science Daily - Paleontology - Tue, 07/23/2024 - 11:35
A pilot study shows that nanoscopic 3-D imaging of ancient bone not only provides further insight into the changes soft tissues undergo during fossilization, it also has potential as a fast, practical way to determine which specimens are likely candidates for ancient DNA and protein sequence preservation.

Ore-some: New date for Earth's largest iron deposits offers clues for future exploration

Science Daily - Paleontology - Mon, 07/22/2024 - 16:58
Research reveals that Earth's largest iron ore deposits -- in the Hamersley Province of Western Australia -- are about one billion years younger than previously believed, a discovery which could greatly boost the search for more of the resource.

New snake discovery rewrites history, points to North America's role in snake evolution

Science Daily - Paleontology - Fri, 07/19/2024 - 17:02
A new species of fossil snake unearthed in Wyoming is rewriting our understanding of snake evolution. The discovery, based on four remarkably well-preserved specimens found curled together in a burrow, reveals a new species named Hibernophis breithaupti. This snake lived in North America 34 million years ago and sheds light on the origin and diversification of boas and pythons.
