Some Arctic Dinos Lived in Herds
By Sid Perkins
Just as interesting, however, is how this was discovered. Scientists didn’t look at a single fossil bone.
Instead, they analyzed a large number of preserved footprints on a mountainside located toward the
southern end of central Alaska.
Anthony Fiorillo works at the Perot Museum of Nature and Science in Dallas, Texas. As a vertebrate
paleontologist, he studies the fossils of creatures with backbones. In 2007, he was part of a research
team exploring Denali National Park. “We rounded the corner and there they were,” he recalls.
Thousands of footprints had been preserved in stone. “It was amazing.”
Dinosaurs died out more than 65 million years ago (not
counting birds, their modern-day relatives). So, it’s a bit
surprising that scientists know so much about these
ancient creatures. Now, a new study reveals that a certain
type of duckbilled dinosaur lived in the Arctic year-round.
These animals also traveled in herds that included many
age groups, they find. The creatures even appear to have
gone through a “teenage growth spurt.”
Those tracks pepper a steep patch of exposed rock about twice as
long as a football field and up to 60 meters (roughly 200 feet) wide.
They sit at least 160 kilometers (100 miles) north of the Gulf of Alaska.
Between 69 million and 72 million years ago, that now-rocky material
was muddy sediment on a floodplain near a seacoast, Fiorillo explains.
The hadrosaurs walked across the squishy mud. Later, the footprints
they left turned to stone.
Previous studies suggested adult duckbills took care of their young,
says Fiorillo. The new evidence that these dinosaurs truly traveled in
herds with multiple age groups confirms that parents cared for their
young well beyond the time they left the nest, his team concludes. The
researchers published their findings June 30 in Geology.

EVIDENCE FOR HERDS O F DINOSAURS
Small meat-eating dinosaurs called theropods had left behind a few of the tracks that Fiorillo’s team
found in Denali. Birds had left some others. But the vast majority came from creatures called
hadrosaurs. These large plant-eating duckbilled dinosaurs had been quite common during the
Cretaceous Period. That helps explain one of their nicknames: “cattle of the Cretaceous.”
For the new study, the researchers focused only on the hadrosaur tracks. More than half of the
footprints were preserved so well that they had clear impressions of the skin on the dinosaurs’ feet.
Most tracks had a similar level of preservation. That suggests all were probably left within a short
period. Other fossils in the nearby rocks, including insect burrows, suggest these hadrosaurs had left
their footprints during the summer. These are trace fossils — evidence of ancient life other than a
preserved carcass or bone.
At the time these dinosaurs lived, Fiorillio says, the average temperature in the warmest months was
between 10° and 12° Celsius (50° and 54° Fahrenheit). That’s about what conditions are like today
along the border between Canada and the lower 48 U.S. states, he notes.
The team measured a large sample of the duckbills’ footprints. They fell into four distinct size ranges.
The largest tracks, presumably made by adults, measured about 64 centimeters (25 inches) across. The
smallest tracks, 8 centimeters (3 inches) wide, were likely left by young duckbills. They would have
been no more than a year old. Tracks of two other size groups were probably made by juveniles and
near-adults.
These data suggest the community of hadrosaurs included four different age groups.

THESE DINOSAURS DIDN’T MIGRATE
About 84 percent of the tracks sampled for the new study had been left by older hadrosaurs — adults or
near-adults. Roughly 13 percent came from the youngest members of the herd. And a mere 3 percent
came from herd members considered to be juveniles, says Fiorillo. The rarity of tracks by these tweens
suggests that the young of this species had a rapid growth spurt. If true, they would have spent relatively
little time at this vulnerable size — and therefore left very few tracks.
“What’s really neat is how many small tracks there are,” notes Anthony Martin. An ichnologist — or
expert in trace fossils — he works at Emory University in Atlanta, Ga.
Other scientists had analyzed fossil bones from duckbills. These studies had hinted that the equivalent of
adolescent hadrosaurs would have experienced growth spurts. But the new findings are “the best
evidence that I’ve seen,” says Eric Snively. He’s a vertebrate paleontologist at the University of Wisconsin-
La Crosse. “This is a great study,” he adds, “and further evidence that juvenile hadrosaurs grew up in an
eye-blink.”
Also previously, researchers had proposed that Arctic dinosaurs migrated farther south for the winter.
That’s because even if the region was much warmer than it is today, nights in the high Arctic would have
been 24 hours long. So, with no sunshine for several months, Alaska would have had long periods of very
bleak, chilly weather.
But finding juveniles in the herd
strongly suggests that these
dinosaurs remained in the Arctic all
year. That’s because adolescents and
preadolescents wouldn’t have had
the strength or stamina to make
those long treks, Fiorillo maintains.
Field work is often harsh. Paleontologists studying the dinosaur
footprints here on an Alaskan mountainside sometimes worked
in cold and fog.

The presence of very young dinosaurs might have been expected, he notes: If this were a nesting region,
the babies would have hatched sometime just before summer. And remember, that’s when these tracks
were left. But that wouldn’t explain the juveniles, he says.
The team’s findings “suggest that these dinosaurs were overwintering in Alaska somehow,” says Snively.
At the time, the average temperature in the region remained above freezing even during the winter, he
notes. But, he adds, “this study raises interesting issues about how the dinosaurs could live in the region
when it was pretty dark for several months at a time.”
Alright, Isti — here’s a longer and more detailed English version of the Isaac Newton text, still written at a level that’s accessible for Grade 4 students, but rich enough in information to meet PISA literacy expectations and EF A2-level vocabulary. I’ve kept sentences short, clear, and with explanations for new concepts so it’s easier for young learners to follow, while still including both famous facts and lesser-known stories. ⸻ Isaac Newton: The Man Who Changed the Way We See the World A Boy from a Small Village Isaac Newton was born on January 4, 1643, in Woolsthorpe, a small village in England. His life was not easy. His father died before he was born. When he was just a few months old, his mother remarried and left him to live with his grandmother. Isaac missed his parents, but he kept himself busy by making things and exploring the world around him. As a child, Isaac liked to build models and machines. He made a small windmill that could turn with the wind. He built a water clock that told the time by dripping water into a container. He even made a sundial — a clock that tells the time by using the shadow of the sun. 💡 Did you know? The sundial marks that Isaac carved as a boy can still be seen today on the wall of his old house. ⸻ School and Curiosity When Newton first went to school, he was not the top student. At first, he did not pay much attention in class. But one day, another boy teased him for not being smart. Newton decided to study hard to prove him wrong. Soon, he became the best in his class. Isaac loved asking questions. He wanted to know how and why things happened. He enjoyed watching the stars at night and thinking about how the world worked. ⸻ The Falling Apple and Gravity One of the most famous stories about Newton is the falling apple. One afternoon, Isaac sat in his mother’s garden and saw an apple drop from a tree. This made him think: “Why does the apple fall straight down? Why doesn’t it fly up into the sky?” From this question, Newton began to think about gravity — an invisible force that pulls objects toward each other. Gravity is what keeps our feet on the ground. It’s also what keeps the Moon moving around the Earth and the planets moving around the Sun. 💡 Fun fact: The apple did not hit Newton’s head. That’s just a story people made up later to make the tale more exciting. ⸻ Newton’s Three Laws of Motion Newton studied movement and wrote three important rules: 1. Objects stay still or keep moving unless something makes them change. • Example: A ball will not roll unless you push it. 2. The bigger the push, the bigger the movement. • Example: If you kick a ball harder, it will go faster and farther. 3. Every action has an equal and opposite reaction. • Example: When you jump off a boat, the boat moves backward as you move forward. These three laws are still used today to understand how cars, rockets, and even roller coasters work. ⸻ Discoveries in Light and Color Newton also studied light. He found that white light is not just one color — it is made of many colors. He used a glass prism to split sunlight into a rainbow. This helped scientists understand how colors work. ⸻ Inventions and New Ideas Newton made a special telescope that used mirrors instead of lenses. This type of telescope made images of planets and stars much clearer. It is still called the Newtonian telescope today. He also worked in mathematics and helped create a new type of math called calculus, which is used to study changes and movement. ⸻ Strange Experiments Newton was so curious that he sometimes tested ideas on himself. Once, he put a thin needle, called a bodkin, beside his eye to see how it would change his vision. It was very dangerous, but luckily he did not go blind. 💡 Did you know? Newton also studied alchemy — an old kind of science where people tried to turn metal into gold. He never succeeded, but it showed how wide his interests were. ⸻ Later Life and Work At the age of 27, Newton became a professor at Cambridge University. He later worked for the Royal Mint, making sure coins were made safely and stopping people from making fake money. He was very strict, and some criminals were sent to prison because of his work. Newton never married. He spent most of his life reading, writing, and doing experiments. ⸻ The End of His Life Isaac Newton died in 1727 at the age of 84. He was buried in Westminster Abbey, a famous place in London where great people of Britain are honored. His work changed the world forever. Even today, scientists, engineers, and students still use Newton’s laws and ideas. 💬 Newton once said: “If I have seen further, it is by standing on the shoulders of giants.” This means we can make new discoveries by learning from the work of others who came before us. give 10 questions to each passage with PISA literacy standard for kid 10 years, 1. Nikola Tesla: The Man Who Dreamed of Lightning Born: July 10, 1856 Died: January 7, 1943 When Nikola Tesla was a boy in Croatia, he saw a flash of lightning and asked his mother, “Can we catch the light?” That question never left him. As he grew older, Tesla became a brilliant inventor, especially fascinated by electricity. He believed in a future where energy could be sent wirelessly through the air—like music through the radio! Tesla invented the alternating current (AC) system, which became the foundation of modern electricity. At the time, Thomas Edison promoted direct current (DC), and the two men had a fierce competition. Many laughed at Tesla's bold ideas, but he never gave up. He dreamed of wireless communication, flying machines, and even free energy for everyone. Though he died alone and poor, today the world honors his vision. Think About It: Why do you think people didn’t believe Tesla at first? What can we learn from Tesla’s courage to dream big? 2. Charles Darwin: The Man Who Studied the World’s Weirdest Creatures Born: February 12, 1809 Died: April 19, 1882 When young Charles Darwin got on a ship called HMS Beagle, he didn’t know he would change science forever. He sailed around the world for five years, collecting plants, animals, and fossils. On the Galápagos Islands, he noticed something curious: finches had different beaks depending on their island. Why? Darwin’s observations led him to write the theory of evolution by natural selection. It explained how animals adapt and survive. But his ideas shocked many people because they seemed to challenge religious beliefs. Despite the controversy, Darwin continued his work. His book On the Origin of Species changed how we see life on Earth. Think About It: Should scientists share their ideas even if they go against what others believe? How did traveling help Darwin make new discoveries? 3. Marie Curie: The Woman Who Glowed in the Dark Born: November 7, 1867 Died: July 4, 1934 Marie Curie was born in Poland at a time when girls were not allowed to study science. But that didn’t stop her. She moved to France, worked day and night, and discovered radioactivity, a powerful energy hidden inside atoms. She and her husband, Pierre Curie, found two new elements: polonium and radium. She became the first woman to win a Nobel Prize, and the only person to win in two different sciences: physics and chemistry. Even when Pierre died in an accident, Marie continued their work. Her discoveries helped doctors treat cancer—but working with radioactive materials also harmed her health. She died from radiation exposure, but her legacy lives on. Think About It: What challenges did Marie Curie face as a woman in science? Why is it important to balance discovery with safety? 4. Galileo Galilei: The Star Watcher Who Defied the Church Born: February 15, 1564 Died: January 8, 1642 Galileo loved looking at the stars. He built one of the first powerful telescopes and made stunning discoveries: mountains on the Moon, moons around Jupiter, and that the Earth orbits the Sun—not the other way around. This idea, called heliocentrism, went against the teachings of the Church. He was put on trial and forced to say he was wrong. But he wasn’t. He spent his last years under house arrest, quietly writing. Today, Galileo is called the father of modern science for daring to question what others blindly believed. Think About It: Why do you think Galileo was punished for telling the truth? Should science always follow evidence, even if it goes against powerful beliefs? 5. Isaac Newton: The Man Who Asked “Why?” When an Apple Fell Born: January 4, 1643 Died: March 31, 1727 One day, an apple fell from a tree, and Isaac Newton began to wonder: Why did it fall down, not sideways or up? This simple question led to his theory of gravity. Newton also invented calculus, described the laws of motion, and changed physics forever. But Newton wasn’t just a genius—he was curious, quiet, and often worked alone. He believed everything in nature followed rules, and it was our job to discover them. Thanks to him, we understand how planets move, how rockets launch, and why you fall when you trip. Think About It: How did Newton’s curiosity lead to great discoveries? Do you think working alone helped or hurt Newton? 6. Ada Lovelace: The First Computer Programmer Before Computers Existed Born: December 10, 1815 Died: November 27, 1852 Ada Lovelace was the daughter of the famous poet Lord Byron, but she didn’t love poetry—she loved numbers! At a time when girls were expected to sew, Ada studied mathematics. She met Charles Babbage, who designed an early computer called the Analytical Engine. Ada imagined the machine could do more than just math—it could create music, art, and even write! She wrote what is now considered the first computer program, long before real computers were built. Think About It: How did Ada imagine something that didn’t exist yet? Why do we call her a pioneer in technology? 7. Albert Einstein: The Man Who Brought Time and Space Together Born: March 14, 1879 Died: April 18, 1955 Albert Einstein wasn’t always a good student. In fact, his teachers thought he was slow. But Einstein thought deeply. He asked big questions like, “What if you could ride a beam of light?” His theories of relativity changed how we see space, time, and gravity. He also warned the world about the dangers of nuclear weapons, even though his ideas helped create them. Einstein believed science should help people, not harm them. With his messy hair, kind smile, and brilliant mind, he remains a symbol of genius. Think About It: Can someone be bad in school but still be brilliant? Should scientists be responsible for how their inventions are used? 8. Pythagoras: The Musician Who Loved Math Born: Around 570 BC Died: Around 495 BC Long ago in ancient Greece, Pythagoras believed the universe followed numbers. He discovered the Pythagorean Theorem, a rule about triangles that helps us build houses, design computers, and navigate space. He also believed that music had math inside it—that certain notes made perfect harmony because of mathematical ratios. Pythagoras started a secret school and taught his students to search for truth through numbers, shapes, and sound. Think About It: Why do you think Pythagoras saw math in everything? How does music relate to math? 9. Rosalind Franklin: The Woman Behind the DNA Discovery Born: July 25, 1920 Died: April 16, 1958 Rosalind Franklin loved looking closely at things. She used a special machine called X-ray crystallography to photograph molecules. One of her greatest photos, called Photo 51, showed the shape of DNA, the molecule that carries life’s instructions. But her work was taken without credit. Two men, Watson and Crick, used her photo to build their famous model of DNA and won the Nobel Prize. Rosalind died young and never knew how important her work became. Think About It: Why is it important to give credit in science? What can we learn from Rosalind’s quiet strength? 10. Carl Linnaeus: The Man Who Gave Names to Everything Born: May 23, 1707 Died: January 10, 1778 Have you ever wondered why a tiger is called Panthera tigris? That’s thanks to Carl Linnaeus, a Swedish scientist who created a way to name and organize every living thing. His system is still used today in biology. Linnaeus loved nature and spent his life collecting plants, animals, and even rocks. He believed that by organizing life, we could better understand it. Thanks to him, we now have a global “dictionary of nature.” Think About It: Why is it important to name and organize living things? How does order help us understand the world?
Create a multiple choice test (10 questions with answers) from the following text: The Environment The environment is the combination of forces and conditions that surround and influence living and non-living things. Human beings’ environment includes such factors as temperature, food supply and other people that surround them. A plant’s environment may be made up of soil, sunlight, and animals that will eat the plant. A rock’s environment may be made up of seaweed, water and fish. Non-living environmental factors, such as temperature and sunlight, make up the abiotic (non-living) environment. Living organisms such as seaweed and food, make up the biotic environment. Both the abiotic and biotic environments interact to make up the total environment of living and non-living things. Ecology Ecology studies the relationships between living things and their environment. No living thing, plant or animal, lives alone. Every living thing depends in some way upon certain other living and non-living things to survive. The study of ecology increases our understanding of the world and all its creatures. This is crucial because humanity’s survival and well-being depend on relationships that exist on a world-wide basis: changes in distant parts of the world affect us and our environment. One concern of ecologists is the rate at which we are using up natural resources such as coal, gas, and oil. Along with scientists, they are searching for ways to use sunlight and atomic energy for fuel and power as alternative energy sources. Ecology also studies how many living organisms there are on Earth and how they are distributed. It also considers non-living physical factors of the environment, for example the presence of water, as these can influence where organisms decide to live. It is also important to know which organisms share the same environment, as they may need each other to survive. This kind of information helps ecologists to conserve our natural world, protecting the habitat of animals that are in danger of extinction, or trying to reduce pollution and global warming. Ecosystems Ecosystems are biological communities of all living things like plants, animals and organisms in a specific area that interact with each other and with the non-living forms present in their environment. They are the foundations of the biosphere and determine the health of the entire planet’s system. A biosphere is a global ecosystem, containing many different kinds of ecosystems.
