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 ...

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 ...

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 ...

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 ...

In order to analyze these microfossils, a pioneering method of analysis has been developed by a research team led by Akizumi Ishida from Tohoku University, in collaboration with experts from the ...

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.
