Scientists who analyzed rare Tyrannosaurus rex footprints in North Dakota say the fearsome predator strolled at roughly 3.5 miles per hour, a pace a healthy human could match without breaking a sweat.

Scientists who analyzed rare Tyrannosaurus rex footprints in North Dakota say the fearsome predator strolled at roughly 3.5 miles per hour, a pace a healthy human could match without breaking a sweat. A team from Liverpool John Moores University and the Denver Museum of Nature & Science studied a 23-foot trackway preserved in the Hell Creek Formation of southwestern North Dakota. The trail holds four three-toed footprints, each about three feet long, spaced at a stride length of roughly 13 feet. Using 3D surface scanning and physical reproductions of the prints, the researchers calculated that the animal moved at between 3.5 and 4.5 miles per hour, barely faster than a brisk walk for a fit adult. Professor Peter Falkingham, who led the…Open
Scientists have used fossilized insect wings and advanced modeling to recreate the strange calls that once filled Jurassic forests, offering a glimpse into a long-lost world that challenges our assumptions about the past. A team led by Dr. Fernando Montealegre-Zapata from the University of Lincoln analyzed 20 fossils from nine insect species, all found in […] The post Researchers reconstruct sounds of Jurassic insects from fossilized wings appeared first on American Almanac .
Scientists have used fossilized insect wings and advanced modeling to recreate the strange calls that once filled Jurassic forests, offering a glimpse into a long-lost world that challenges our assumptions about the past. A team led by Dr. Fernando Montealegre-Zapata from the University of Lincoln analyzed 20 fossils from nine insect species, all found in China’s Inner Mongolia region and dating back roughly 165 million years. These ancient bugs, ancestors of today’s grasshoppers and katydids, left behind wing structures with microscopic ridges and a scraper known as a plectrum, clues that helped the team reconstruct their calls. Using microscope scans, laser measurements, computer modeling, and machine learning, the researchers…Open
Scientists digging in Egypt's southwestern desert have uncovered fossilized remains of five extinct shark species dating to the Late Cretaceous period, a find that includes the first fossil record of its kind for Egypt and the African continent.

Scientists digging in Egypt's southwestern desert have uncovered fossilized remains of five extinct shark species dating to the Late Cretaceous period, a find that includes the first fossil record of its kind for Egypt and the African continent. Archaeologists excavating phosphate beds in the Duwi Formation, a geological deposit laid down when sea levels ran between 320 and 850 feet higher than they stand today, pulled 14 fossilized shark teeth from what was once a warm, tropical marine environment. The discovery, published in the journal Cretaceous Research , represents a new assemblage of extinct lamniform sharks, an order that includes some of the most formidable predators ever to patrol the world's oceans. The find matters because it…Open
Tonight on “Jesse Weber Live”: Thousands of people have descended on Roswell, New Mexico, for the annual UFO Festival. Ben Hansen reports from the event as enthusiasts gather to celebrate all things extraterrestrial. Plus, Harvard professor Avi Loeb joins the show after being named to a new White House UFO Advisory Council. The longtime friend of the program discusses the group’s goals and what he hopes to learn. Also, Taylor Swift fever has taken over New York City as anticipation builds for what some are calling the wedding of the century between Swift and Travis Kelce. And a dinosaur mystery decades in the making has been solved. Researchers say a fossil tucked away for years belonged to a species that lived about 82 million years…
A fossil sat unnoticed in a museum drawer for more than 40 years — until one scientist realized it was something extraordinary: the first dinosaur fossil ever discovered in Antarctica, dating back 82 million years. On today’s “Hot Take with Jesse Weber”: We break down how a single fossil reshaped our understanding of Earth's ancient past, what it reveals about prehistoric Antarctica and why overlooked discoveries can change science forever. What do you think is still waiting to be discovered? Drop your questions, comments and hot takes in the chat!
