The Cretaceous basins of Brazil have long been recognised as treasure troves of ostracod microfossils, whose diversity and preservation offer an unrivalled window into past environments and basin ...

Two of the ostracod species occur also in the Trinity of Texas and Arkansas, and the entire ostracod fauna bears a close resemblance to Upper Purbeck-Wealden of England. The absence of known Lower ...

We report changes of deep-sea ostracod fauna during the last 370,000 yr from the Ocean Drilling Program (ODP) Hole 704A in the South Atlantic sector of the Southern Ocean. The results show that faunal ...

But after 100 million years, “for ostracods, there must be an advantage, otherwise it wouldn't exist anymore.” The scientists identified a new species of ostracod, Myanmarcypris hui, in the amber.

Comparing minute crustaceans called ostracods offers a great way to study sexual dimorphism, or the physical differences between the sexes. So far, studies have been limited by a focus on living ...

Microfossils may capture a jump in the complexity of life that coincided with the rise of oxygen in Earth's atmosphere and oceans, according to an international team of scientists.

Discovery of new types of microfossils may answer an age-old scientific question Date: September 6, 2022 Source: Tohoku University Summary: The Gunflint Formation, which straddles Lake Superior's ...

Using 3D X-ray reconstructive technology, scientists analyzed several ostracod specimens, studying their limbs and reproductive organs. Experts discovered ripe sperm inside the sperm receptacles ...

Assorted microfossils from the Ediacaran Khesen Formation, Mongolia. Each fossil is on the order of 200 microns maximum dimension. (Yale University) A Yale-led research team has discovered a cache of ...

These microfossils have been degraded, exposed to high temperatures, and are now a mass of mature organic matter, says Maldanis. Still, they outline the shape of the original cell, pointing to a ...
