Scientists have found the oldest known ancestor of octopuses – an approximately 330 million-year-old fossil unearthed in Montana.
In an ancient shallow bay of what is now Montana, the body of an octopus-like creature the size of a fist was buried on the seafloor. Some 325–328 million years later, a new paper published in Nature Communications provides ...
New research led by scientists at the American Museum of Natural History and Yale shows that the oldest ancestors of the group of animals that includes octopuses and vampire squids had not 8 but 10 arms. The study, which ...
It wasn't the result the scientists wanted.
A pair of researchers, one with the University of Western Australia, the other NOAA National Systematics Laboratory, has recorded on video a young bigfin squid swimming just above the seafloor at an approximate depth of 6,200 ...
The fossilized remains of a gigantic ichthyosaur, colloquially known as a "sea dragon," were recently uncovered at the Rutland Water Nature Reserve in the UK. Measuring at least ten meters in length and with a skull weighing ...
The last common ancestor of cephalopods and vertebrates existed more than 500 million years ago. In fact, a squid is more closely related to a clam than it is a to a person. Even so, the two lineages independently evolved ...
Australia has one of the longest coastlines in the world. And it's packed with life of all shapes and sizes—from lively dolphins leaping offshore, to tiny crabs scurrying into their holes.
The two-meter skull of a newly discovered species of giant ichthyosaur, the earliest known, is shedding new light on the marine reptiles' rapid growth into behemoths of the Dinosaurian oceans, and helping us better understand ...
For generations, scientists have relied on a handful of organisms to study the fundamentals of biology. The usual suspects—fruit flies, zebrafish, and mice, among others—all have short lifespans, small body size, can be bred ...
