because of climate change. Climate change killed the animals that lived there
As I konow they lived in Patagonia, Argentina, so probbably fossils were found there.
There are so many well preserved fossils because there are so many fossils, some will be well preserved. In certain locations at certain times the conditions will be right for preserving living tissues.
The discovery was significant because we found prove of pangea in other parts of the Earth.
Index fossils are very important to geologists because they identify geological time periods. Index fossils are found within a specific layer of rock- So when one finds the age of the rock layer, that is also the age of the index fossil.
Fossil records contain radiation, and the older the fossil is, the less radiation it gives off. Scientists study how much radiation is in the fossil record, and they find out how old the earth is.
Fossils from the Jurassic period and before abound in Alberta's badlands. Large dinosaurs are found often with fossils be nearly complete.
because they are found by waters edge
Because they are a special part of Alberta and the fossils found here are one of a kind.
Calymene celebra or trilobite is the Wisconsin state fossil. Wisconsin was heavily glaciated so not very many fossils exist. No dinosaur bones have been found.

Jellyfish have no real bones, so had no fossils in the sense of the word.
The Canadian province of Alberta is a treasure trove of ancient fossils. Thousands of dinosaur bones have been found in the rolling plains of the area. Alberta was an ancient sea bed. This likely accounts for the large amount of fossils.
Dinosaurs are reconstructed from fossils, petrified remains, trace fossils, and comparisons with existing animals.
There are so many well preserved fossils because there are so many fossils, some will be well preserved. In certain locations at certain times the conditions will be right for preserving living tissues.
So few dinosaur fossils have been found in Antarctica because the entire continent is covered in ice, making it hard to dig and/or search for large fossils.
A number of dinosaurs, such as Amphicoelias are known from only one fossil specimen. Many other dinosaurs were never preserved as fossils and so will never be known to mankind.
