Paleontologists have identified a new species of dinosaur, Khankhuuluu, which is being described as the closest-known ancestor to the giant Tyrannosaurs. The finding by an international team of researchers – led by Jared Voris and Dr. Darla Zelenitsky in the Faculty of Science at the University of Calgary – is published in the journal Nature. 

A team of researchers from Japan, China, and Brazil has announced the discovery of a new species of pterosaur from the Late Cretaceous of Japan, marking the first time a pterosaur has been named based on body fossils found in the country.

In a paper published in SCIENCE CHINA Earth Sciences, a team of researchers performed comparative analyses of the microbial ectoenzyme activities under atmospheric and in situ pressure conditions in the water column of the Mariana Trench, by conducting pressure-retaining sampling, isobaric transfer, and enzymatic assays in the Challenger Deep. It highlights the importance of pressure-retaining sampling and isobaric enzymatic assays and provides valuable insights into microbial ectoenzymatic activities in the deep ocean.
