What observation did scientists make about dinosaurs not being lizards?

There have been a number of observations. First of all, although they are still considered reptilian, analysis of ancestor animals shows that dinosaurs were more closely related to crocodiles than to lizards. More importantly, however, dinosaurs have a number of characteristics not found in modern reptiles. While modern reptiles have their legs jutting out to the sides while dinosaurs walked with their legs vertically beneath them.
Many dinosaurs, particularly the two-legged carnivores known as theropods, have skeletal features that are closer to those of birds than to those of reptiles. Finally, while evidence shows that some dinosaurs had scales, a growing number of dinosaurs are being found to have had feathers.

Why did scientists assume dinosaurs were cold blooded?
The first traits of dinosaurs that scientists noticed were reptilian. In fact, the first animal to be called a dinosaur was iguanadon, named for its iguana-like teeth. So from their discovery until the mid-20th century, scientists regarded dinosaurs simply as giant reptiles. It was not until the 1960s that new discoveries started to point toward an at least some dinosaurs being warm blooded.
How did scientists react to Linnaeus theory?
They gasped and some died from excitement and danced and jumped for joy before being wiped out with the dinosaurs:)
Which dinosaur is considered by scientists to be a reptile but not a dinosaur?
Your question is logically impossible. You must mean, "What prehistoric reptile is not considered by scientists to actually be a dinosaur?" The answer is that there were many mammal-like reptiles that predated the dinosaurs and were not dinosaurs. One example being Dimetrodon, which went extinct millions of years before the first dinosaurs evolved. Dinosaurs were not reptiles, but shared characteristics with both reptiles and birds. They were actually more like birds.
Currently there is a controversy over whether which of the following organisms is a direct descendant of dinosaurs?
Recent discoveries have virtually proved the the birds are the only living descendants of dinosaurs.In fact the similarities between birds and some avian dinosaurs have lead scientists to begin to consider birds as not only evolving from dinosaurs but actually being dinosaurs in their own right.
What animal is a cousin to the giraffe?
Oddly, the closest living relatives of crocodilians are birds, due to crocodiles being related to dinosaurs. After that, the next closest relatives would be lizards and snakes.
What does direct observation do?
Observation changes the force being observed.
When dinosars ruled the earth who was next on earth?
The time period of the dinosaurs was called the age of reptiles. This is when reptiles dominated Earth, like dinosaurs, lizards, etc. But when the dinosaurs died out 65 million years ago, most of the reptiles died. this is when mammals took control and started dominating. But humans didnt come out to being until around 4 million years ago.

What is a basilisk lizard?
Not closely. They are both reptiles, are so are related in that sense, just as you are related to a rabbit (or a fox or a bear...). If we go far enough back, lizards and dinosaurs share a common ancestors, which was probably something that looked superficially like a lizard, or the surviving tuatara which is found only in New Zealand. However, the dinosaurs' real surviving relatives are birds and crocodiles
