TheJURASSIC Era
Why would a dinosaur with feathers be a bad index fossil?
Dinosaurs with feathers have been found through a relatively wide range of geologic time. Not counting birds feathered dinosaurs can be found from the Jurassic period to the end of the Cretaceous period.
How are index fossils different from original fossil remains?
Index fossils are original fossil remains, just a specific subcategory of them. Index fossils are used by paleontologists to identify a particular period of time and often a subperiod of time - the specific fossil is chosen as an index fossil because it is very specific to a time period and allows the other fossils and remains around them to be identified to the same time period.
What is fossils organisms that lived a short period of time called?
They are called index fossils.
What is a measurement of the earth history divided into time period?
