To accurately answer your question, I would need to know which specific fossils you are referring to, as different fossils can originate from various geologic periods. If you provide the names of the fossils or their characteristics, I can help identify the geologic period during which they formed.

What is the jursssic period?

The Jurassic is the second of the three periods of the Mesozoic. It was named for the Jura Mountains, where many of its fossils have been found.


What 3 criteria do fossils have to meet un order to be considered an index fossils?

To be considered index fossils, fossils must meet three key criteria: they should have a wide geographic distribution, indicating that the species existed over a broad area; they must be limited to a short time range in the geologic record, allowing for precise dating of rock layers; and they should be easily recognizable and distinctive, facilitating identification. These characteristics make index fossils valuable for correlating and dating geological formations.


Which era contains fossils of dinosaurs?

Dinosaurs lived during the Mesozoic Era, which is divided into three periods: Triassic, Jurassic, and Cretaceous. Fossils of dinosaurs have been found primarily from the late Triassic to the end of the Cretaceous period.

What three kinds of information can geologist gather from a study of fossils?

The three kinds of information can geologists gather from a study of fossils is amber fossil, trace fossil, and the carbon film. Wait a second, no that's not right. Those are just three kinds of fossils. Those aren't three kinds of information.1. Fossils tell scientists the types and sizes of animals that lived in the distant past;2. Tests made on fossils tell scientists approximately how long ago they lived;3. The types of materials in which fossils are found tell scientists the area where the fossil first died, the cooling rates of some different materials, and the times of lava flows, as well as other items of information;4. Comparing different fossils of the same type, from different areas, tells scientists the times of certain geologic events, such as an ice age, or a volcanic eruption;5. The layers of rock (or soil) in which fossils are found can tell scientists some of the geologic history of the geographical area in which the fossil was found. For example, sometimes seashell fossils are found in the rock of high mountains! That can only mean that the high mountain was once on the floor of an ocean or river. Over time, plate movement, volcanic eruption, and earthquakes have moved the old ocean floor (or river bottom) 'way up to the top of a mountainThere you go.

Can you make a sentence comparing age of three fossils using ancient?

By definition, we could say all three fossils are 'ancient'. Fossils provide an ancient record of plants and animals.
