Through finding dinosaur fossils we can determine what they looked like and how they lived. It is important because we can they estimate how they lived and their features, it might also tell us what the world used to be like, by some of their characteristics.
Fossils play a major role in the understanding of our current and past history of biota worldwide. From studying fossils, an placing them in chronological order, we are able to better determine what kind of living situations caused certain adaptations to occur within a certain species which result in the evolved fauna we have today, or the extinct animals we can study. A close study of Palaeontology can give us a much greater understanding as physical appearance and internal structure of the animal.
There are no living direct ancestors of dinosaurs, but dinosaurs are a branch of reptilian life which are abundant today.
Fossils, defined as the physical remains of past life, provide invaluable information to scientists. They not only provide a picture of a long-distant past, but also information that can be used to understand the evolution of today's plants and animals and clues for the future of our planet.
Trilobites: The Index Fossil There are many thousands of known species of trilobite fossils found worldwide. Trilobites are considered to be good index fossils because they evolved so rapidly, and this allows geologists the ability to date the rocks in which the trilobites are found. The discovery of trilobites is second only to the discovery of dinosaurs, and new species of trilobites are still being discovered today.
Fossils are used to show changes because they are permanent. These fossils are also old and show evolutionary changes in species alive today.
Fossils are here today because way before humans were living on land there were dinosaurs first and some people still see the fossils today from when the dinosaurs used to be here but now dinosaurs are enstinct .
Because they are alive today, birds are dinosaurs. And because of fossils.
When a dino dies, it becomes a fossil. We know that the dinosaurs existed because they left behind fossils we see today.
There is not a dinosaur that I know is living to this day but there are animals that have descended from the dinosaurs.
One reason is that there were a lot of fossils in many layers of rock and then suddenly, there are a lot fewer. Also, there don't appear to be many dinosaurs alive today. So, they went extinct. Do you really mean "how" did the dinosaurs go extinct?
Fossils exist of nearly all formerly living organisms, with some exceptions, from single celled bacteria to the largest dinosaur. Marine organisms comprise the bulk of fossils that are easily available today.
During the times of the dinosaurs, Greece did not exist. The lands looked extremely different to how they do today. Dinosaurs dominated every single continent on the globe, so, yes, dinosaurs did live in what is nowadays recognised as Greece.
Yes there is evidence of Mesozoic dinosaurs in the form of fossilised bones of hundreds of clades, ranging from embryos to adult, eggs, coprolites and trackways. There are dinosaurs living today, the birds which are theropod dinosaurs. There is overwhelming evidence that birds derived from dinosaurs. There are now many fossils that show many types dinosaurs had feathers.
The non avian dinosaur fossils are so old that no DNA is left. Therefor, you can't find the DNA from non avian dinosaurs. However, birds, which are considered dinosaurs, exist today and it isn't hard to get bird DNA.
to compare them to our animals today and if their related some how
On the contrary, all the evidence shows that, excluding birds, all dinosaurs died out long before people evolved. Dinosaur fossils date to 65.5 million years ago or later, and human fossils date to less than 2.3 million years ago. However, if you count birds as dinosaurs, then the proof is that they're still here today.
True sturgeon evolved early in the Cretaceous. They have barely changed since then, making them living fossils. Today, however, many are threatened by humans.
