What are the prerequisites for a fossil to be a useful in biostratigraphy?
To be practical, index fossils must have a limited vertical time range, wide geographic distribution, and rapid evolutionary trends. Rock formations separated by great distances but containing the same index fossil species are thereby known to have both formed during the limited time that the species lived.
What determines the type of fossil that is formed?
Explanation : The type of fossil which is formed depends on the conditions under which the organism died for e.g whether he died under cold or hot conditions, along with the reason that led to his death.
What are the two main characteristics of an index fossil?
A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time. Index fossils are the basis for defining boundaries in the geologic time scale and for the correlation of strata.
How big can an ammonite be?
1.8 metres
Do fossils have healing properties?
Fossils have a very calming and soothing energy promoting feelings of tranquility, contentment and comfort. In healing, fossils may be helpful in assisting with curing diseases and aliments of the bones, skeletal system, hands and feet.
Do fossils have energy?
Do they really begin with fossils? All fossil fuels contain carbon, and all were formed as a result of geologic processes acting on the remains of organic matter produced by photosynthesis—the process by which green plants and certain other organisms transform light energy into chemical energy.
Where are Orthoceras fossils found?
Orthoceras fossils are found all over the world. These popular fossils are found in Sweden, Morocco, and even in Antarctica. When archaeologists find orthoceras fossils, they are abundant.
What is Orthoceras fossil?
The fossils commonly known as orthoceras are extinct “straight-shelled” cephalopods that lived during the Upper Devonian period around 370 million years ago. They lived inside of their shell, had tentacles they could use to grab food and used jet propulsion, squirting water to move.
