Top 10 Dinosaurs Discovered In The US

From terrifying predators to gigantic gentle
giants, here are 10 amazing dinosaurs that were discovered in the USA! 10. Dakota – The Duck-Billed Dinosaur. Dakota is the nickname given to a fossil of
a Duck-Billed Dinosaur, scientifically called a Edmontosaurus Annectens, which lived at
the very end of the Cretaceous Period. Dakota was first noticed by a then teenager
named Tyler Lyson in 1999 on a ranch near the southwestern North Dakota town named Marmarth,
which is also part of the Hell Crest Formation. Excavation for the fossil did not start until
2004 when Lyson was in college and teamed up with British Paleontologist Phillip Manning. Dakota has skin, bones, and tendons preserved
in sediment. Scientists believe that Dakota was a plant
eater, roamed the area of the United States about 65 million years ago, weighed around
between three to four tons, measured at about 35 feet long, and could run about 28 miles
per hour. Dakota is now housed at the North Dakota Heritage
Center and States Museum in Bismarck, North Dakota. 9. Tyrannosaurus Rex
While several bones for the Tyrannosaurus Rex has been found in several areas around
the United States of America, one of the most well-preserved Tyrannosaurus Rex fossils was
discovered in Montana’s Hell Creek Formation. The skull weighed in about 2,500 pounds, lived
about 66 million years ago, making its living toward the end of the Cretaceous Period, and
died around the age of 15. The skull also had about 20 percent of its
former body intact, and is about 85 percent as large as the biggest Tyrannosaurus Rex
found previously. Tyrannosaurus Rex’s are known to be meat
eaters, had razor sharp teeth, about 40 feet long, and stood up to 20 feet tall. The T-Rex skull was named Tufts-Love Rex after
to two paleontologists to uncover the skull, Luke Tufts and Jason Love. Luke and Jason were volunteers at Seattle’s
Burke Museum and part of a University of Washington expedition. Tufts-Love Rex is going to be on view at the
Burke Museum of Natural History and Culture in Seattle, Washington, once it is all cleaned,
preserved and ready for view, as Tufts-Love Rex was only found a little over a year ago. 8. Triceratops
Recently, in fact as recent as August of this year, a Triceratops was found on a construction
site in the town of Thornton, Colorado. The Saunders Construction crew was digging
for a new fire and police station when one of a geotechnical engineer on site noticed
something inconsistent with the surrounding claystone and sand. After ordering the crew to stop, water was
poured around the item, when is when they noticed it was a very unusual find. In response, they secured the area and notified
the Denver Museum of Nature and Science. Dinosaur curator Joe Sertich, who works for
the Denver Museum, states the dinosaur is a Triceratops fossil, about 66 million years
old and lived at the end of the Cretaceous period, and is believed to have been about
the size of a rhino. So far, records so that a total of 12 Triceratops
bones have been uncovered at this site. These bones include both brow horns, part
of the skull that surrounds the brain, parts of the snout, parts of the frill, which is
the shield behind its head, the lower jaw, parts of the neck, some vertebrae and ribs. The possible weight of this dinosaur has not
been mentioned, but just one rib weighed in at 40 pounds! 7.) Dakotaraptor
Unlike other dinosaurs like to Tyrannosaurus Rex, the Dakotaraptor was first found in 2005
and finally given its name in 2015. The Dakotaraptor was found in South Dakota’s
Hell Creek Formation and dated to the end of the Cretaceous period. The dinosaur was discovered by Robert DePalma
and his team. Robert is the curator of vertebrate paleontology
at the Palm Beach Museum of Natural History. This dinosaur is said to be about 18 feet
long, wings stretched about 3 feet, and is explained to be like a giant crested bird-like
dinosaur. The Dakotaraptor had long arms with one of
the lower arm bones showing quill knobs, which paleontologists believe means this dinosaur
had some feathers, however it is believed that these dinosaurs could not fly. Furthermore, the dinosaur had long rear legs
with a very large sickle claw on the second toe, which is believed was used for protection
against other dinosaurs and was measured at 9.5 inches. Dakotaraptors are believed to be able to run
quickly and were carnivores. And now for number 6 but first be sure to

Sophie the Stegosaurus, who was named after the daughter of the donor who made the dig
possible even though scientists are not sure of her gender, was found by paleontologist
Bob Simon in 2003 at Red Canyon Ranch in Wyoming. The skeleton of Sophie is one of the most
complete dinosaur skeletons in the world at 85%. It is said that Sophie roamed the lands about
150 million years ago and is considered a young adult when she died. Sophie is said to have been about 18 feet
long and 9.5 feet tall. Stegosaurus dinosaurs, like Sophie, are said
to have been plant eaters and through analyzing Sophie’s bones, scientists believe that
they moved slowly. Today, Sophie is that the National History
Museum in London where paleontologists and scientist hope to learn more about Stegosaurus
dinosaurs through studying Sophie. 5.) Lophorhothon
Lophorhothon was first discovered in Alabama’s Mooreville Chalk Formation. The remains of the Lophorhothon were discovered
in the 1940s and consisted of a fragmented and disarticulated skull, and incomplete postcranial
skeleton, less than one half of the entire skeleton was found. The Lophorhothon was named in 1960 by paleontologist
Wann Langston Jr. The Lophorhothon lived 65 to 99 million years
ago in the Cretaceous period. This dinosaur would have been about 14 feet
long, would walk on 2 or 4 legs, and was estimated to be a juvenile as this dinosaur was smaller
than the average adult sized Lophorhothon. 4.) Claosaurus
The Claosaurus was first discovered in Smokey Hill River, Kansas in the late 1800s. It was identified as a Claosaurus by Othniel
Charles Marsh in 1890 after being identified as a Hadrosaurus by Marsh in 1872. The parts of the dinosaur skeleton found were
the articulated postcranial skeleton and partial skill fragments. A Claosaurus is known to have a slim body
and feet, long legs and tail, and small arms. They can grow anywhere from 12 to 15 feet
long and usually 6 feet tall, and weighed around 1,000 pounds. Today, the Claosaurus is housed at the Yale
Peabody Museum in New Haven, Connecticut. 3.) Ankylosaurus
While parts of different Ankylosaurus skeletons have been found throughout the 20th century
in the United States, the most recent discovery occurred in Judith River Formation in Montana
last year. The discovery of the Ankylosaurus, who is
now called Z. crurivastator because of its resemblance to Zuul in the 1984 “Ghostbuster’s”
movie. Z. crurivastator was discovered by researchers
from the Southern Alberta Dinosaur Project while they were looking for T. Rex remains
and stumbled on to Z. crurivastator’s tail. After further digging, the researcher’s
discovered that Z. crurivastator remains were miraculously intact, which makes Z. crurivastator
the most complete Ankylosaurus dinosaur in the world. Like other Ankylosaurus dinosaurs, Z. crurivastator
had a long, spiked tail of a little over 6 feet long. Altogether, Z. crurivastator was 20 feet long
and would have probably weighted about 5,500 pounds. Z. crurivastator is said to be about 75 million
years old, which means it would have lived in the Cretaceous Period. Furthermore, the researchers found that some
of the dinosaur’s soft tissues were preserved, which can further advance the research about
the Ankylosaurus dinosaurs. Today, Z. crurivastator is at the Royal Ontario
Museum in Toronto, Canada, where it continues to be preserved and analyzed by the museum’s
paleontologists’ Victoria Arbour and David Evans. 2.) Appalachiosaurus
The Appalachiosaurus was first discovered in July of 1982 by geologist David King in
Montgomery County, Alabama in the Demopolis Chalk Formation area. The dinosaur wasn’t named until 2005 by
paleontologists Thomas Carr, Thomas Williamson, and David Schwimmer. Through two different excavations, the remains
of the Appalachiosaurus are about 40 percent complete. When David discovered the dinosaur, he found
fragments of skull, limbs, a hind foot, and pelvic elements. In the second excavation, completed by personnel
from the Red Mountain Museum in Birmingham, Alabama, uncovered more of the Appalachiosaurus’s
bones. This dinosaur is thought to be a juvenile
as it is measured at 23 feet, which is only about two-thirds the size of an adult Appalachiosaurus. It is believed that the Appalachiosaurus would
have weighed about 1,300 pounds and to have lived during the Cretaceous Period, about
79 million years ago. The tail of the Appalachiosaurus was used
mainly for balance as it walked on its hind legs. The Appalachiosaurus is now housed at the
McWane Center in Birmingham, Alabama, which is the place where two museums, including
the Red Mountain Museum combined. While the pieces of the Appalachiosaurus is
not always on display, the McWane Center is known to put pieces on display from time to
time. 1.) Maiasaura
The Maiasaura dinosaur is one of the few dinosaurs with a female name and this is for good reason,
as the name means “good mother” and this is what a Maiasaura was known to be. The Maiasaura was first discovered in 1978
by Laurie Trexler at Two Medicine Formation in Montana and named a year later by Jack
Horner & ‬Robert Makel. One of the most important areas that Maiasaura
has been discovered is known today as “Egg Mountain” in Montana, which is an area full
of nests with eggshells, babies, juveniles, and adult Maiasaura dinosaurs and has been
the only finding that has shown how dinosaurs treated their young. Altogether, since its first discovery in 1978,
about 200 specimens have been uncovered. Maiasaura’s are believed to have been about
30 feet long, around 8 feet tall and weighed in about three to four tons. A baby Maiasaura was under 14 inches long
and would weigh about one and half pounds. These dinosaurs lived in the Cretaceous Period
around 70 to 80 million years ago. They also show a unique featured compared
to other dinosaurs of their kind, as they have a little knob between their eyes. Because of the number of specimens that were
found in Egg Mountain, several studies have been conducted at about Maiasaura, including
what their lifestyle would have been like. Scientists believe, through these studies,
that Maiasaura’s traveled in herds, believed to have been to protect each other and their
young from enemies and would stay around their young (however we are not sure for how long). Thanks for watching!! Which one of these would you have liked to
