Mydlarz added that no other Atlantic species grows as large or forms such an extensive lattice. “These are the only ones that provide that real sort of 3D structure,” she said. There are some pockets of coral survivors, including remnants to the north, near Miami and Broward County. However, the researchers think there’s little hope they will spur a comeback. …

Water pulls life together. Shorelines turn into busy corridors where birds, hoofed mammals, and different species of human ancestors, or hominins, crossed paths. At Lake Turkana in northern Kenya about 1.5 million years ago, a short-lived window of wet silt captured that traffic with unusual clarity. Scientists have studied those impressions and found a tight, almost real-time record …

Rocks formed immediately before and after non-avian dinosaurs went extinct are strikingly different, and now, tens of millions of years later, scientists think they’ve identified the culprit—and it wasn’t the Chicxulub asteroid impact. In a study published Monday in the journal Communications Earth & Environment, researchers argue that dinosaurs physically influenced their surroundings so dramatically that their disappearance led to …

A version of the dodo bird (Raphus cucullatus) could make a return someday soon. Colossal Biosciences announced this week several milestones in its quest to bring the extinct species back to life. On Wednesday, the Dallas-based company reported that its researchers at the Avian Genetics Group have successfully grown pigeon primordial germ cells (PGCs) in the lab, a scientific first. …

Scientists in Australia are deep-freezing the shoot tips of a critically endangered tree to preserve its DNA in case the species goes extinct. Only 380 specimens of the angle-stemmed myrtle (Gossia gonoclada) remain in the wild, with about 300 of them concentrated in the City of Logan area in southeast Queensland. If scientists manage to cryopreserve a diverse collection of …

If you were lucky 74,000 years ago, you would have survived the Toba supereruption, one of the largest catastrophic events that Earth has seen in the past 2.5 million years. While the volcano is located in what’s now Indonesia, living organisms across the entire globe were potentially affected. As an archaeologist who specializes in studying volcanic eruptions of the past, …

Mount Tabor must have a better publicist, because Rocky Butte is really Portland’s more important and influential extinct volcano. The Rocky Butte Preservation Society is doing its best to promote its mountain’s reputation with a slew of informative newsletters, history walks and trash cleanups. The society will host what its organizers say is the the first concert inside Rocky Butte’s …

Facebook Tweet Email Link Tens of millions of years ago, an apex predator resembling a giant crocodile stalked the humid freshwater floodplains of southern Patagonia. Measuring up to 11.5 feet (3.5 meters) long and weighing about 550 pounds (250 kilograms), it ate whatever it could catch. Including some dinosaurs. Near the southern tip of South America, in Argentina, scientists recently …

At dawn in the deep waters off North Maluku, Indonesia, a team of technical divers raised their camera lights and found themselves face to face with a creature once known only from stone. The brown spotted coelacanth, an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia, famous for vanishing before the last dinosaur fell, a survivor of a …
