The first discoveries

The clade Dinosauria was originally defined by Sir Richard Owen in 1842, in a two hour speech that reportedly held the audience captivated. The original dinosaurs of this new group were Megalosaurus, Iguanodon and Hylaeosaurus. However, each of these animals was known only from fragmentary specimens. It wasn't until the discoveries of dinosaurs in North America in the mid-19th century that people began to get a clearer picture of what dinosaurs looked like.

It is generally accepted that the first discovery of dinosaur remains in North America was made in 1854 by Ferdinand Vandiveer Hayden during his exploration of the upper Missouri River.

Near the confluence of the Judith and Missouri Rivers (shown above) Hayden's party recovered a small collection of isolated teeth which were later described by the Philadelphia paleontologist Joseph Leidy in 1856, in the Proceedings of the Academy of Natural Sciences of Philadelphia.

An important, more complete specimen

A short two years later, Leidy had the honor of describing the first reasonably complete dinosaur skeleton the world would know, Hadrosaurus foulkii. Named after its discoverer William Parker Foulke, this specimen was recovered during quarrying of a sand pit in Haddonfield, New Jersey.

The real significance of this specimen was in its limb proportions. For the first time scientists studying these animals could see that some dinosaurs were bipedal, walking on two legs instead of on all fours. Bipedalism was a revolutionary thought for a reptilian posture.

This specimen, now on display at the Academy of Natural Sciences of Philadelphia, was originally mounted in a free-standing bipedal pose by Benjamin Waterhouse Hawkins in 1868.

The records for attendance at the Academy show that visitation increased three-fold with this new exhibit, testimony to the public's long-standing and intense fascination with dinosaurs.

For many years, Hadrosaurus foulkii was the only dinosaur on public display. Duplicate casts of the skeleton were made for other institutions both in the United States and in Europe.

Dinosaur skeletons were found for the first time in abundance in the Garden Park area of Colorado and at Como Bluff, Wyoming, in the late 1870s. These specimens initiated the First Great Dinosaur Rush in North America, driven largely by the efforts of a Philadelphia paleontologist, Edward Drinker Cope (on the left), and Othniel Marsh (on the right), a paleontologist from Yale University.

These two men started as friends but became bitter rivals in a feud of legendary proportions. The stories surrounding these two include tales of armed field parties, spies, and intercepting shipments of fossils intended for the other. Many of these stories have been exaggerated with time but they clearly point out the bitterness of this rivalry. As a result of the tremendous collecting efforts of these two paleontologists, the public became aware of the fascinating world of the Late Jurassic, and was presented the opportunity to know the largest of all dinosaurs, the sauropods.

The Second Great Dinosaur Rush took place in the badlands of the Red Deer River in southern Alberta. Dinosaur remains had been known from this region as early as 1884 but it wasn't until 1910 that this region became an active collecting area. It was here that the second great collecting rivalry took place between Barnum Brown of the American Museum of Natural History in New York and C.H. Sternberg of the Geological Survey of Canada. However, unlike the rivalry between Cope and Marsh, this rivalry resembled more of a friendly competition. Also unlike the earlier efforts, the result of this collecting provided insights into the world of the Late Cretaceous.

Early Dinosaur Discoveries in North America

One thing that I noticed was that they all had similar houses.

# data[].attributes.body
I had noticed that people were in front of stuff they liked or had wanted people to see and they also never smiled in those photos.

# data[].attributes.body
I noticed that mast people were not smiling and they we standing/ sitting near something they are proud of.

# data[].attributes.body
I noticed that most people in the images were not smiling, in front of their houses, and with their prized possessions.

# data[].attributes.body
That everyone had to work and there was not school for hardly anyone.

# data[].attributes.body
I notice that all the pictures had something that someone was admiring

# data[].attributes.body
They all had old houses

# data[].attributes.body
One thing that I noticed is some people were standing by something they like. Like the piano.

# data[].attributes.body
it looks like they built most of there houses and most of them have to work (even kids)

# data[].attributes.body
Everyone were working on one thing to help the family and them not their self or education.

# data[].attributes.body
I thought it was weird how no one smiled in the pictures.

# data[].attributes.body
They had horrible houses, no-one wanted to smile in photos, and they were very proud to own things.

# data[].attributes.body
That life was really hard

# data[].attributes.body
The houses were made out of sod and the families were big.

# data[].attributes.body
I can infer that the life was tough, noticing the sod houses and that the people weren`t smiling.

# data[].attributes.body
How come all the woman were wearing dresses and boys dress shirts

# data[].attributes.body
I can infer that life was hard for the people, and that they were poor, because they didn't have a lot of belongings, and the ones that they did have were not exactly fancy.

# data[].attributes.body
They were all on a prairie, there were few trees and they all had sod houses.

# data[].attributes.body
Why couldn't they smile or why did they take the photos at their valuables

# data[].attributes.body
What I think they all had in them is they all looked poor, and had loads of land.

# data[].attributes.body
Since they didn't really have anything I'm guessing they had to work real hard.

# data[].attributes.body
I noticed that none of them were smiling and they were all wearing lots of layers of heavy clothing when there was no shade outside because there were no trees.

# data[].attributes.body
that they have to work hard and that they didnt have many recourses. Also they were very poor and were proud of expensive things.

# data[].attributes.body
I can infer that they didn't have much resources.

# data[].attributes.body
How come not many people were wearing nice clothes?

# data[].attributes.body
I can see the people are squinting because of the sun, but they are wearing long sleeves and long pants, even the men.

# data[].attributes.body
All the woman wore dresses past their ankle.

# data[].attributes.body
I can infer that most of the people were farmers.

# data[].attributes.body
Why does everyone have there WHOLE family there was not one of just parents or kids.

# data[].attributes.body
They probably all had to work 24 hours and tough jobs.

# data[].attributes.body
NO ONE SMILED :0

# data[].attributes.body
It was weird how everyone had to sit down and it didn't madder if they were taller or not.

# data[].attributes.body
I think that My Daniel is going to be about Julia Creath remembering when she was a kid and she found a dinosaur with Daniel. I'm pretty sure Mrs. Freeman said that herself. Or its on the back of the book.

# data[].attributes.body
Why did they all have really big and long dresses

# data[].attributes.body
Julia Creath remembers back to when she was a farm girl and her brother died because he was obsessed with dinosaur fossils

# data[].attributes.body
How did that person get a organ?
It would be hard to put that in a covered wagon.

# data[].attributes.body
I feel like My Daniel is going to be about someone loves dino fossils and wants to learn more and does and goes out and tries to find more.

# data[].attributes.body
I believe that My Daniel is going to be about how she remembers her life as a young person live and her brother

# data[].attributes.body
I can infer that they had to work very hard each day, and they did not have any of the modern amenities that we have today, or machines to help with the farming. I also think that because they lived pretty much in the middle of nowhere, they couldn't go to the store to get groceries. They had to grow everything themselves.

# data[].attributes.body
They all worked very hard and didn't play video games all day long.

# data[].attributes.body
I feel like it will be about how paleontologists live.

# data[].attributes.body
Its going to be about how her brother died and how she found a dinosaur even though everyone was looking for bones.

# data[].attributes.body
I think that Daniel probably died from someone trying to find a dinosaur and killed him to get it first, so I think the story is about Julia telling the story of Daniel.

# data[].attributes.body
I think that Julia is going to remember all of this stuff.

# data[].attributes.body
Why didn't they take the pictures inside the house if it was so hot outside?

# data[].attributes.body
Is it hard for them to get started living in the prairie.

# data[].attributes.body
I think that My Daniel Will have an interesting setting with a lot of dinosaur foot prints and bones.

# data[].attributes.body
I think that the book will be about Julia and Daniel participating in the dinosaur rush and finding dinosaur fossils.

# data[].attributes.body
I think it will be about the grandmother remembering a long time ago when her brother was still alive.

# data[].attributes.body
I think it will be about how Daniel would have been the first to discover the dinosaur when...

I don't know I didn't read the story yet
