Traditionally the earliest dinosaur was considered Eorapter. Examples have been found in the Ischigualasto Basin in Argentina dating from 230 million years ago.
A recent discovery of a pro-sauropod was found possibly predating this discovery in Madagascar.
Fossils themselves can very rarely be dated by any means...their age is usually judged by the geological assessment of the area and layer in which they are found
Pecten fossils are mostly found on the east coast of the United States.
They are mostly found on, or very near, the surface. They have probably been quite deeply buried at some point ( a lot can happen in, say, 70 million years) but due to tectonic movements and erosion, they finish up where we can find them. If all the Jurassic rocks were buried at about 300m, then our knowledge of dinosaurs would be impressively small.
Biogeography is the study of the distribution of species (biology) spatially (geography) and temporally (history). Biogeography aims to reveal where organisms live, at what abundance, and why they are or are no) found in a certain geographical area. Biogeography does not support the theory of evolution any more then when (history) you (biology) moved into your house (geography).
Fossils indicate several things about Earth's past: - the organisms that lived then, and by extension the organisms in their food chain - the climate in the area where the organism lived - how plate tectonics have moved landmasses that once were joined together
The Gobi Desert is known for its dinosaur fossils.
Big Bend National Park has many fossils. The fossils are not only of dinosaurs; fossils of Quetzalcoatlus, the largest known flying reptile, come from this area.
yes California the saber toothed cat is the state dinosaur.
Maybe not THE richest but certainly the most powerful and influential in world politics. Around the mid-19th century Great Britain ruled over one fourth of the worlds' land area.
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.
I believe it's Alberta because some dinosaurs have been named after places there like the Albertosaurus
The area of Dinosaur World - Arkansas - is 263,045.667456 square meters.
The area of Dinosaur National Monument is 853.255 square kilometers.
Fossils that are found over a wide area.
The area of Dinosaur Valley State Park is 6,170,322.924361728 square meters.
Well, most are found in the area where they were first found like in africa but a lot have been taken out for mueseams
Fossils are important to Alberta because you can learn more about the history. Alberta is home to Dinosaur Provincial Park, as well as the Tyrrell Museum. This area provides the province with valuable tourism dollars. Fossils are also important because with them scientists are able to learn what the climate in this region was like millions of years ago, giving them insight as to what the climate may be like in the future. Another reason fossils are important is because as their name implies that is what 'fossil fuels' are made of.
