Fossils can be found all over the world, usually in sedimentary rock, which comprises the bedrock of the majority of the planet. Limestone and shale are particularly good fossil medium.
There were many dinosaur fossils found in South America. Certain species of dinosaur can only be found in South America such as Argentinasaurus and Giganotosaurus
the oldest fossils can be found the deepest in the ground. in other words, the deeper the fossil, the older it is (unless something has happened to the ground, such as an earthquake etc.)
The vast majority of fossils are found in sedimentary rock.
Probably, yes. California has some of the largest concentrations of Smilodon fossils in the world and I would assume that, with its close proximity, Nevada would have some too.

No, fossils are actually very difficult to find. The majority of fossils found are marine invertebrates. They are usually found in sedimentary rock. However, there is plenty of sedimentary rock that contains no fossils at all.

Yes, hundreds of species of fish can be found in the fossil record.

It can help show that continental drift happened, if you find the same fossils on different continents. This would mean that the continents had to be close together if the fossils are found on land.
Similar species of fossil can be found on separate, but adjacent, continents
Modern animals may be related to fossilized organisms.

The type species of Spinosaurus is Spinosaurus aegypticus, and it is known from fossils found in Egypt. The other possible species is Spinosaurus maroccanus, and it is known from teeth found in Morocco.
The vast majority of fossils are found in sedimentary rock.
Amargasaurus fossils have been found in Patagonia, Argentina. This dinosaur species lived during the Early Cretaceous period, approximately 130 million years ago.
