Fossil rudist bivalves (Vaccinites) from the Al-Hajar Mountains, United Arab Emirates. Beer stein-shaped distant relative of modern clams captured snapshots of hot days in the late Cretaceous. Earth turned faster at the end of the time of the dinosaurs than it does today, rotating 372 times a year, compared to […]

Coral reefs are constantly under threat from environmental stress. Credit: David Suggett The existence of coral reefs, in all their abundant biodiversity and beauty, relies largely on a complex symbiosis between reef-building corals and microalgae. This finely tuned, fragile, partnership is constantly under threat from environmental stress—most notably the twin […]

A previously unknown significant source of carbon just discovered in the Arctic has scientists marveling at a once overlooked contributor to local coastal ecosystems — and concerned about what it may mean in an era of climate change. In a Nature Communications paper released today, aquatic chemists and hydrologists from The University […]

This new fossil specimen of the worm Utahscolex ratcliffei helped University of Kansas graduate student Anna Whitaker solve a 50-year-old marine-worm mystery. This specimen preserves the everted mouthparts (upper left). The body of the worm is covered of rows of tiny round plates, which were used to redescribe the species. […]

Underwater coral drilling start. Credit: Jason Turl New international research has found a worrying change in the Indian Ocean’s surface temperatures that puts southeast Australia on course for increasingly hot and dry conditions. The work led by The Australian National University (ANU) and the ARC Centre of Excellence for Climate Extremes has […]

Coral reefs face many threats, including pollution, climate change, overfishing, storm damage, and outbreaks of crown-of-thorns starfish. In order to see how these threats impacted reefs, scientists on the Global Reef Expedition conducted over 400 coral and reef fish surveys and created over 406 square kilometers of detailed seafloor habitat […]

Schools of scissortail sergeants and blue-green chromis swim above a stand of staghorn coral off the island of Moorea. Credit: Jeff Liang Coral reefs are not doomed. Although human activities threaten the iconic ecosystems in many different ways, scientists maintain that reefs can continue to thrive with the right assistance. […]
