Bryce Canyon National Park is home to the world's largest concentration of hoodoos, making hiking here feel like you're on another planet. I recommend hiking around the rim to take in the vastness of the spires.
Four protrusions appear to be arranged in pairs, each consisting of two connected branches surrounding a central depression. We really don't understand what any of these features represent anatomically.
For the Win brings together an extraordinary collection of objects that commemorate the defining moment of victory in sports, meticulously crafted from spectacular gems and minerals, and explores how athletics can resonate far beyond the field of play, Museum President Sean M. Decatur said.
The exhibition is the embodiment of the scenes of the famous franchise, with the use of realistic animatronics and detailed settings and with the interactive presence. The large dinosaurs and dramatic sets usually draw the attention of the visitors and one can easily miss numerous small details in the course of the exhibition.
The Spinosaurus is a sail-backed, crocodile-snouted dinosaur that Hollywood depicted as a giant terrestrial predator capable of taking down a T. rex in Jurassic Park 3. Then they changed their mind and made it a fully aquatic diver in Jurassic World Rebirth—a rendering that was more in line with the latest paleontological knowledge. But now, deep in the Sahara Desert, a team of researchers led by Paul C. Sereno discovered new Spinosaurus fossils suggesting both scientists and filmmakers might have got it all wrong again.

Sauropodshumongous reptiles with a long neck and tail and thick, elephantlike legsplayed a starring role in the dinosaur ecosystem, according to a new study. These massive dinosaurs are the largest creatures to ever walk on land. But they also played a crucial part in the food chain, the study authors write, acting as ecosystem engineers. The research was published on Friday in the New Mexico Museum of Natural History and Science Bulletin.
The AMNH has one of the biggest dinosaur halls and exhibits-and they're iconic for a reason! The nearly complete Stegosaurus skeleton nicknamed Apex (one of the most complete ever discovered) has been on display and continues to draw crowds with its massive plates and spikes.
At first glance, it looked like Wooller and his colleagues might have found evidence that mammoths lived in central Alaska just 2,000 years ago. But ancient DNA revealed that two "mammoth" bones actually belonged to a North Pacific right whale and a minke whale-which raised a whole new set of questions. The team's hunt for Alaska's last mammoth had turned into an epic case of mistaken identity, starring two whale species and a mid-century fossil hunter.
For example, reader David Erickson had this on his mind: If there were aliens 66 million light-years from Earth, how big a telescope would they need to see dinosaurs? Ha! I love this question. I've thought of it myself but never worked out the mathexcept to think, Probably pretty big, which turns out to dramatically underestimate the actual answer.
Dinosaur fever gripped the Western world during the early 1900s, fueled by the discovery of new, ever larger and more spectacular dinosaurs in Europe and especially in North America. Interest in these fossils was not merely driven by academic curiosity. Dinosaur skeletons and research had become a status symbol for museums and their financiers, whether government or private, and colonial powers turned to their areas of influence to find new remains.
Although there are many amber stones containing a single creature, there are fewer that include two or more, as is the case with a pair of mosquitoes trapped in amber 130 million years ago which tell us that, back then, males also sucked blood. Even more extraordinary is when several organisms can be seen interacting, either eating the other, acting as a parasite, or cooperating.
In a sudden turn of events last Wednesday the U.S. Food and Drug Administration agreed to review Moderna's new mRNA flu vaccine, according to the company. The announcement came roughly a week after Moderna revealed that the FDA had rejected its application. The company said the agency originally called the plan for the vaccine's phase 3 trials acceptable, But its position changed after top FDA official Vinay Prasad overruled the agency's reviewers, according to STAT.
Now, in a recent study published in Geology, retired University of New Mexico geologist Karl Karlstrom and his colleagues conclude that the asteroid's impact shook Marble Canyon hard enough to dislodge great chunks of stone and send a landslide tumbling into the river. The debris formed a natural dam that backed up the Colorado for over 50 miles to near present-day Lees Ferry.
Wooden objects carrying the marks of carving and use could be the oldest wooden tools ever found. Researchers dated the artefacts, found in what is now Greece, to 430,000 years ago - and suggest they might have been made by early Neanderthals or their ancestors, Homo heidelbergensis. A separate study describes 480,000-old flint-knapping tools made from antler and elephant bone, from what is now the United Kingdom.
We have little physical evidence of these interactions turning violent, however, because burials were rare and carnivores were more likely to finish off their prey. That's why the embellished burial site of a 15-year-old from 27,000 years ago is an important window into the past: the teenager's bones indicate he was mauled by a bear. The finding represents some of the first evidence of its kind.
The oldest known pieces of sewn clothing have been discovered in a cave in Oregon, potentially rewriting all of human history. Researchers from the US uncovered pieces of animal hide stitched together from the end of the last Ice Age, approximately 12,000 years ago. That would mean that humans in North America had advanced skills, specifically for working with plants, animals, and wood, thousands of years before the Great Pyramid of Egypt was constructed.
Specifically, I take people around downtown Seattle to explore the stone that makes up our buildings. On the corner of Second Avenue and Cherry Street is an elegant six-story structure built with two-foot-tall blocks of rough-hewn sandstone, about 44 million years old, quarried in Tenino, Washington. The building rose soon after much of downtown Seattle burned to the ground in 1889, and the jagged stone gives it a feeling of rugged permanence, certainly what the city needed after the great fire.
