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.

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.

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.

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!

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.

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.

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.

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.

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.

Long Tom

Image: Richard Hedrick

This nickname refers to a Founding Father, one of our nation's earliest presidents, famously born in Virginia. Author of the Declaration of Independence, he also oversaw the Louisiana Purchase in 1803. Monticello was his home, now a museum and historical site. You know who we're talking about, don't you?

2

Grand Wrestler

Image: Fiona Murray-deGraaff

This is certainly a powerful nickname, right? And it was attributed to a great man who led our nation during the Civil War. Author of the famous Gettysburg Address , he is also famous for having issued the Emancipation Proclamation in 1863. His beard and stovepipe hat are forever etched in our memory. What's your guess?

3

American Fabius

Image: Matt Briney

Quintus Fabius Maximus was a Roman general known for his astute strategies during the Punic Wars. In honour of that general and for the clever tactics he deployed during a conflict in our country's history, one of our presidents earned the nickname "American Fabius". He was also nicknamed "The father of his country." Do you know who we are referring to?

4

The Human Iceberg

Image: Annie Spratt

This nickname may seem a bit harsh, perhaps even exaggerated. "The Human Iceberg" was given to our 23rd president, who led the country from 1889 to 1893, due to his rather stiff and reserved demeanor.

Before becoming president, this commander-in-chief served in the Union Army during the Civil War, and he was also the grandson of a former president! Do you know who he is?

5

Old Man Eloquent

Image: Tim Mossholder

The man who was known as "Old Man Eloquent" not only served as president, but also served in the US House of Representatives for nearly 17 years. Before becoming president, he helped negotiate the Treaty of Ghent, which ended the War of 1812. Additionally, he was the son of the 2nd president of the United States!

6

His Little Majesty

Image: rupixen

This is another nickname that points to physical features, and we could say it was not used with the best intentions. However, this president was also proudly known as the "Father of the Constitution." In addition, he served two consecutive terms and led the country through the War of 1812. If you want to know who he is, keep reading!

7

Long Tom: Thomas Jefferson

Image: Alicia Razuri

Thomas Jefferson, the 3rd president of our country, was very tall, a feature that earned him the nickname "Long Tom." He was 6' 2'', making him one of the tallest presidents in US history. According to descriptions from the time, President Jefferson was well-proportioned, and his height was above average compared to his contemporaries. Did you know that?

8

Grand Wrestler: Abraham Lincoln

Image: Ed Fr

At 6' 4'', Abraham Lincoln was slightly taller than Thomas Jefferson, but his nickname "Grand Wrestler" came not from his height but from his impressive wrestling skills. That's right! As a young man, the 16th US President was a fantastic wrestler, and his athleticism and physical toughness were outstanding qualities even in his later years.

9

American Fabius: George Washington

Image: Priscilla Gyamfi

Before becoming the 1st president of the United States, George Washington served as the Commander of the Continental Army during the American Revolutionary War. He was known for his clever, strategic use of attrition, avoiding massive battles and conserving troops, a tactic that contributed enormously to the American victory.

He earned the nickname "American Fabius" because his techniques resembled those of the Roman general Quintus Fabius Maximus, who fought against Hannibal's Carthaginian forces during the Second Punic War.

10

The Human Iceberg: Benjamin Harrison

Image: René DeAnda

Benjamin Harrison, the 23rd President of the United States, earned the nickname "The Human Iceberg" due to his reserved and formal character in both political and social interactions. However, despite this rather harsh nickname, many admired his seriousness and intellect.

11

Old Man Eloquent: John Quincy Adams

Image: Larry Ferreira

You were right! "Old Man Eloquent" is the nickname given to John Quincy Adams, the 6th President of the United States, who was also the son of the 2nd president, John Adams.

As we mentioned, he served in the US House of Representatives for 17 years, and it was during that time that his excellent oratory skills and great speeches truly stood out, earning him this peculiar yet favorable alias.

12

His Little Majesty: James Madison

Image: Richard Hedrick

Unlike Lincoln and Jefferson, James Madison was known for his short stature. His 5' 4'' made him the shortest president in US history and earned him the nickname "His Little Majesty".

Initially used by his adversaries, the moniker later took on a more humorous and even affectionate tone, with the word "Majesty" emphasizing Madison's strong and important role in shaping our nation.

George Washington had wooden teeth

Image: Todd Trapani

Washington suffered from dental problems throughout his adult life and did wear several sets of false teeth. However, he did not wear wooden ones.

They were made from materials like ivory, metal, and springs . The "wood" myth probably comes from the staining of ivory and from 19th-century caricatures.

2

Salem witches were burned at the stake

Image: Sofia Holmberg

We hold the long-standing belief that the accused Salem "witches" were burned like European witch victims.

However, in the Salem (and colonial New England) trials of 1692–1693, convicted witches were almost always executed by hanging ; burning at the stake was not the legal penalty under English law in the colonies.

3

Paul Revere rode and shouted, "The British are coming!" alone

Image: Mikhaël Noury

He may be riding alone in the Boston statue that represents the dramatic midnight ride in which he warned of the British troop movements.

But in reality, Revere was one of several riders who spread word of the British troop movements; Longfellow’s 1860 poem amplified and simplified the story, including the shouted line, which would have been unlikely among colonists.

4

Betsy Ross designed the first American flag

Image: Heather Newsom

We have heard again and again the myth that Betsy Ross stitched the first Stars and Stripes after being asked by George Washington. In reality, this tale grew from a family tradition promoted more than a century after 1776. Historians have found no contemporary documentation proving that she designed the first official flag.

The flag’s creation was likely more complex and collective. Ross has always remained a folk symbol, but there is no proof that she was the sole designer.

5

Mrs. O’Leary’s cow started the Great Chicago Fire

Image: raquel raq

The myth: a cow kicked over a lantern in Catherine O’Leary’s barn and caused the 1871 conflagration. The cow story originated in sensational newspaper reporting and later became part of folklore.

Investigations have never produced conclusive proof, and modern historians treat the O’Leary–cow tale as an unfair scapegoating and probably apocryphal. The fire’s precise origin remains a mystery.

6

"Molly Pitcher" was a famous woman who operated a cannon at Monmouth

Image: Foysal Razu

The story of Molly Pitcher, a single heroic woman who supposedly took over a cannon when her husband fell, may have been created to represent several women . The best documented candidate is Mary Ludwig Hays, but the legend also reflects the broader contributions of women who supported troops during the Revolutionary War, with or without having been widowed.

7

Davy Crockett died fighting to the last at the Alamo

Image: Eric Francis

Did Crockett heroically fight to the death amid hand-to-hand combat at the Alamo? Well, that was indeed the location of his death, but sources conflict about the manner.

Some eyewitness accounts and Mexican records suggest he may have been captured and executed; other accounts describe him dying in combat. The neat heroic portrait was shaped by 19th-century myth-making.

8

The Declaration of Independence was signed on July 4, 1776

Image: The New York Public Library

It is widely believed that all signers of the Declaration of Independence scribbled their names on it on July 4, which is why we celebrate that date.

Congress adopted the Declaration on July 4, but most delegates did not sign the parchment copy until August 2 of that year (and a few added their names even later). July 4 became the commemorative date for adoption and celebration, not the universal signing day.

9

The Pilgrims’ "First Thanksgiving" centered on a big roast turkey, like today

Image: Tyler Donaghy

No, the 1621 harvest meal at Plymouth did not feature the same turkey-centered feast we picture now.

Accounts mention venison and wildfowl, but the menu and ritual context were very different from modern Thanksgiving dinners. The idea of an annualized, turkey-centered national holiday developed much later (19th century onward).

10

Thomas Edison single-handedly invented the light bulb

Image: Tamas Pap

Many believe that Edison alone invented the incandescent light bulb out of whole cloth. But electric light was the product of decades of work by many inventors (from Humphry Davy to Swan and others).

Edison’s contribution was significant improvements and the critical development of a commercially viable, manufacturable system, but he did not "invent" electric light in isolation.

11

Pocahontas dramatically saved John Smith from execution

Image: EricThriller

The myth holds that Pocahontas heroically rescued Captain John Smith by throwing herself over him at the moment of execution.

Disney may have amplified the romantic and dramatic aspects of this story. John Smith’s account of a dramatic rescue appears in later writings and is debated by historians. Many scholars now interpret the scene as a ritual adoption or a ceremonial act rather than a literal rescue, or they suspect Smith embellished the story.
