Fossil treasures

10 jaw-dropping dinosaurs discovered in America

Image: Fausto García-Menéndez

The territory of the United States is a real goldmine for paleontologists. Over the years, some of the most impressive and well-preserved dinosaur fossils in the world have been discovered in our country. From the likable Apatosaurus to the fearsome Tyrannosaurus rex, the finds have provided a fascinating glimpse into prehistoric life. Read on to learn about the 10 most famous and influential American dinosaurs.

1
Anchisaurus

Anchisaurus is one of the first dinosaurs discovered in American territory, although it was not correctly identified at the beginning. The first fossil of this herbivore was found in East Windsor, Connecticut , in 1818, but it was then believed to be part of a human skeleton. In subsequent years, other specimens of this species were uncovered in the area.

It measured 8 to 20 ft in length and lived 210 million years ago in the Portland Formation, Northeastern United States. In the late Triassic and early Jurassic periods, the Connecticut Valley was a dry, steep depression, and it was possible to pass from here to the east and the center of what is now Africa. This explains why some dinosaurs lived both in America and other continents.

Triceratops

One of the most iconic dinosaurs found in America is the Triceratops, a herbivore that lived 70 to 65 million years ago, right at the end of the Age of Dinosaurs, in the Late Cretaceous. Its name derives from Greek and means "face with three horns". One of the largest horned dinosaurs**,** it stood around 7.5 ft tall and weighed about 5 rhinoceroses, the equivalent of 10 tons.

Fossils of this dinosaur have been found in abundance in the Hell Creek Formation in Montana and South Dakota. No fossils of this dinosaur have been found on any other continent. Triceratops has been the state dinosaur of Wyoming since March 1994.

3
Allosaurus

Allosaurus was one of the largest carnivores of the Jurassic period and its remains in the United States have been found mainly in the Morrison Formation, which covers states such as Colorado, Utah, and Wyoming. It lived 155 to 145 million years ago in North America, Africa, Australia, and possibly China. Also, did you know that the Allosaurus fragilis is the state fossil of Utah?

This bipedal dinosaur was an agile hunter with powerful jaws and sharp teeth. It was a theropod, not as huge as the largest carnivore, Tyrannosaurus rex, but just as fearsome. Allosaurus was bigger than an elephant and heavier than a rhino. Its name means "different lizard" due to its rare concave vertebrae.

4
Stegosaurus

Another inhabitant of the Morrison Formation was the Stegosaurus, famous for its dorsal plates and spines on its tail, which it used for defense. Stegosaurus used to walk on all fours, grazing on low vegetation. Its head was perfectly adapted to this way of feeding. It was first described in 1877 by Yale paleontologist Othniel Charles Marsh, and its name means "roof(ed) lizard".

This Jurassic herbivore has been discovered in several states in the western United States. Scientists have found many fossils, showing that it was a very common creature for 10 million years, despite its tiny brain, small head, and useless teeth. The discovery of the Stegosaurus has helped them better understand the anatomy and behavior of armored dinosaurs.

5
Tyrannosaurus rex

Is Tyrannosaurus rex the most famous dinosaur on the planet? Portrayed by pop culture to the hilt, this formidable predator is known for its gigantic size, razor-sharp teeth, and bipedal posture. However, its popularity has a logical explanation. T. rex is also one of the best-represented dinosaurs in the fossil record, with several complete specimens discovered, particularly in the states of Montana, South Dakota, and Wyoming.

Based on bones found in the late 19th century, paleontologist Henry Fairfield Osborn recreated the first drawing of this gigantic creature. He named it Tyrannosaurus rex, meaning "tyrant lizard king," because it is believed to have been the most dangerous dinosaur and the largest land carnivore of all time. Although it is estimated that up to 1.7 billion T. rex dinosaurs lived on Earth, only about 30 nearly complete skeletons have been found. Think about that!

6
Deinonychus

This small but ferocious theropod lived during the Cretaceous period about 115-108 million years ago. Deinonychus is known for its sickle-shaped claws on its feet, used for hunting. Its name, unsurprisingly, means "terrible claw". Like all bipeds, it moved only on its hind legs and is believed to have been able to run at 25 miles per hour: more than the average Olympic champion.

Deinonychus fossils were found in Utah, Oklahoma, Montana, and Wyoming, in rocks of the Cloverly Formation and Antlers Formation. The study of this species, beginning in the 1960s, revolutionized the way scientists thought about dinosaurs, providing fascinating new insight into smaller predators.

7
Ankylosaurus

Ankylosaurus is one of the best-known armored dinosaurs, which lived at the end of the Cretaceous period. It had bony protrusions on its head and all over its body as protection against the teeth and claws of predators. The armor was made up of small plates of bone welded together, constituting a shell as effective as that of turtles.

This gigantic herbivore roamed the jungles of North America about 68-66 million years ago, almost as well protected as a modern tank. The first specimen of Ankylosaurus was found in 1906 in the Hell Creek Formation, near Gilbert Creek, Montana. Other fossils of this species were discovered in other parts of Montana and Alberta, Canada, in the following years. However, to this day, it has not been possible to obtain a complete skeleton.

8
Hadrosaurus

The first Hadrosaurus fossils were discovered by William Parker Folke, an amateur paleontologist, in 1838 in Haddonfield, New Jersey. The excavation site, known as the Hadrosaurus foulkii Leidy site, is now a National Historic Landmark. Hadrosaurids are known for their duck-billed mouth, with a powerful jaw containing several rows of teeth for chewing all kinds of leaves.

In 2004, scientists found a mummified Hadrosaurus specimen in North Dakota. This fossil is extremely unusual and valuable, as dinosaur soft tissue including skin and muscle is rare. This find allows us to learn more about this species and how they lived 67 million years ago.

9
Diplodocus

Diplodocus means "double beam" and is so named because of the double bones in its tail. This was one of the longest animals on earth. It was about 79-85 ft long, 15 ft high, and weighed 15 tons. It could reach the tops of towering trees for food, and its small head allowed it to forage in vegetation where few other dinosaurs could reach.

Although some Diplodocus fossils were discovered earlier near Cañon City, Colorado, the most notable find came a few years later. In 1899, Funded by Scottish-American steel tycoon Andrew Carnegie, members of the Carnegie Museum of Natural History found a well-preserved Diplodocus skeleton in the Morrison Formation of Sheep Creek, Wyoming. With these fossils, the museum created a composite mount that became very popular and even got to tour the world.

10
Apatosaurus

Apatosaurus is one of the best-known sauropods that inhabited North America during the Jurassic period. These herbivorous giants, with their long necks and tails, have also been discovered in the Morrison Formation, mainly in Colorado and Utah. It is believed to have lived 150 million years ago, at the end of the Jurassic period.

Apatosaurus could reach 69-75 ft in length, 20 tons in weight, and was one of the largest sauropods. It had a long neck containing 15 huge bones supported by powerful muscles that allowed it to feed on the leaves of the tallest trees. Perhaps this dinosaur sounds familiar. It has been the inspiration for numerous beloved animated characters: Littlefoot from The Land Before Time and Arlo and Poppa Henry from Pixar's The Good Dinosaur are Apatosauruses.

Life finds a way

From raccoons to foxes: take a look at 12 types of "urban wildlife"

Image: jennifer uppendahl

For many Americans, seeing a black bear scratching its back on a pole in a city street is not that strange. Many mammals, birds, reptiles, and insects that eat a wide variety of foods are moving in and changing their behaviors as they learn urban survival skills.

1
Coyotes

Image: Ray Hennessy

Coyotes have a natural talent for survival, and they are built to thrive in any environment, including cities where food is readily available everywhere.

As it has been noticed multiple times, coyotes have deciphered how semaphors work and wait for the red light to cross the street.

2
Black bears

Image: Bruce Warrington

Studies have shown that female black bears living in urban areas aged one to one and a half years weighed nearly twice as much as their country counterparts. Some of those urban female bears produced cubs, while none of the rural bears of the same age reproduced.

Curiously, bears seem to know when it is trash day and will scavenge for food in trash cans on those dates specifically.

3
Raccoons

Image: Ralf Volkmer

Raccoons that live in urban environments are more exploratory than their country cousins, taking more time to investigate the squares. Some raccoons even figure out how to yank bungee cords off of trash cans .

These city animals are also more social, traveling in pairs more often than their rural relatives.

4
Bald eagles

Believe it or not, in the 1960s, the bald eagle was on the verge of extinction due to the use of pesticides. But since those pesticides have been banned, their population has rebounded, and they're no longer on the list of endangered species.

City eagles need only a place to nest and a clean source of food, which can even be a trashcan, and they’ve figured out how to use city infrastructure like cellphone towers, bridges, and cranes along waterways .

5
Pigeons

Image: Dawood Javed

Possibly the most urban animal on the list, aside from rats, pigeons are uniquely suited to urban life. They can recognize human faces , so they know which people have fed them before.

These creatures have an incredible ability to distribute themselves, so there are never more pigeons than available food. A park with twice as much food as another park will also have twice as many pigeons.

6
Booklice

Image: Brett Jordan

Whether we see it or not, our homes are filled with insect life. One of them, booklice, has found that the starch in book bindings makes an ideal food source.

Booklice have adapted to suck the moisture directly out of the air and can live off that vapour for three weeks, avoiding dehydration.

7
Squirrels

Image: Mark Brennan

Squirrels and urban environments have gotten along for a long time now. There’s ample food and shelter, and few natural predators. They’ve learned to live in much greater densities in cities than they do in other environments, and they can tell which humans will feed them .

8
Sparrows

Image: Carlos Quintero

The sparrows that live in New York City have become night owls, staying out later to feed because the bright lights around buildings draw plenty of insects .

9
Rats

Image: Joshua J. Cotten

Almost no one would call a rat clean, but contrary to popular belief, city rats tend to carry fewer diseases and parasites than rural ones because they have less contact with livestock excrement from farms, and their human neighbors don’t harbor many parasites.

10
Ospreys

Image: KaroGraphix Photography

Ospreys have seen their numbers grow in North America partially because they have forsaken trees in favor of building their 250-pound nests on power poles, cell phone towers, channel markers , and other human-made structures.

11
Crows

Image: Veronica Dudarev

Crows are very smart creatures, and they have learned to use the city infrastructure to their advantage. These birds drop nuts and bones from great heights to crack the hard outer shells so that they can reach the food inside. City crows simply drop the previously impenetrable food into the street and let the cars crack it open .

12
Tomcods

Image: John Werner

Nature can adapt to almost anything, and tomcods are living proof of this. A very polluted segment of the Hudson River is home to these humble fish, who have adapted to its contaminated waters through genetic variations that allow them to thrive in such conditions.

One hit is better than none

12 famous actors who could never escape their most famous role

Image: Julee Juu

What movie do you remember Macaulay Culkin from? Or Tobey Maguire? Or Helen Hunt? The fact that we all remember them from the same movies is not a coincidence. Some actors make such a strong impression in a single role that it sticks with them for the rest of their lives.

Take a look at these 12 famous stars who everybody knows for a single role. Which one do you think is more than a one-hit wonder?

1
Edward Furlong

Moving on from childhood is a natural transition for most people, except for child actors, who often experience it as a kind of identity loss, since they are publicly connected to their younger selves.

Edward Furlong is forever known as John Connor , the kid from Terminator 2: Judgment Day . Though he has appeared in some movies in minor roles, he never truly moved beyond his most famous role.

2
Macaulay Culkin

Image: Liubomyr Vovchak

One of the most famous child actors of all time, Macaulay Culkin, became a phenomenon with Home Alone , released more than 30 years ago. The film made him a household name.

Since then, Culkin has appeared in a few minor roles, but nothing approaching the impact of the movie that made him famous.

3
Carrie-Anne Moss

Released in 1999, The Matrix quickly became a cultural phenomenon, and Carrie-Anne Moss shot to fame as Trinity .

She later appeared in the sequels and in a few Marvel projects, but Trinity remains her most iconic and defining role.

4
Tobey Maguire

Tobey Maguire became a Hollywood star thanks to his role as Peter Parker in Spider-Man (2002) , with his upside-down kiss scene becoming iconic.

He returned for Spider-Man 2 and Spider-Man 3 before the franchise was rebooted with a new actor. But he reprised the role in Spider-Man: No Way Home (2021), earning widespread acclaim from fans. So far, it remains the biggest role of his career.

5
Helen Hunt

Image: Ralf Sauter

Helen Hunt won four Emmys and three Golden Globes for Mad About You , and later earned an Oscar for As Good as It Gets .

Despite these honors, her later roles didn’t match the staying power of those roles. The Sessions (2012) marked one of the last peaks of her career in terms of critical acclaim, even though she has continued to take on other roles since then.

6
Demi Moore

Image: Taylor Heery

Demi Moore has often made headlines for her personal life, and while her acting career has included other notable roles ( G.I. Jane , A Few Good Men ), there is one that has truly stood the test of time.

Ghost (1990) , in which she starred alongside Patrick Swayze , remains her most successful and iconic role to this day.

7
Elijah Wood

Image: Ergo Zakki

Elijah Wood has taken on a variety of roles in films like Eternal Sunshine of the Spotless Mind and Green Street Hooligans , as well as series like Wilfred and Dirk Gently’s Holistic Detective Agency .

But despite his diverse work, most people still remember him best as Frodo Baggins from The Lord of the Rings trilogy .

8
Anthony Perkins

Image: Maxime Roedel

Perhaps one of the earliest examples of an actor best known for a single role, Anthony Perkins is remembered above all for his portrayal of the murderous motel owner Norman Bates in Alfred Hitchcock’s 1960 thriller Psycho .

He reprised the role in three sequels, none of which matched the success of the original film.

9
Christopher Reeve

Image: MeSSrro

Christopher Reeve became forever linked with Superman , a role that brought him both fame and typecasting. He chose roles carefully, hoping to protect the image of the character he had defined.

In his 1998 memoir Still Me , Reeve reflected on life before and after his 1995 accident, noting that Superman had both opened and limited doors in his acting career.

10
Hugh Jackman

Image: Jack O'Rourke

A man of many talents, Hugh Jackman is an actor, singer, and producer. But he is forever linked to the character that brought him international fame: Wolverine , from the X-Men film franchise .

Although he’s acclaimed for roles in The Greatest Showman and Les Misérables and has appeared in numerous films and stage shows, winning many awards, he is still best known to this day for his role as the mutant superhero.

11
Daniel Radcliffe

Image: Artem Maltsev

Another famous child actor, Daniel Radcliffe, rose to fame at age twelve for portraying the title character in the Harry Potter film series . He starred in all eight films, from Harry Potter and the Philosopher’s Stone to Harry Potter and the Deathly Hallows – Part 2 .

He has since appeared in a variety of roles, but none has matched the impact of his most famous one.

12
Mark Hamill

Image: Venti Views

The last entry on this list is one of the most iconic examples of an actor identified with a single role. Mark Hamill is best known for starring as Luke Skywalker in the Star Wars franchise .

And although he has also built a strong career as a voice actor (notably as the Joker), the movies were such a cultural phenomenon that his persona became forever linked to this character.
