Evidence best indicates that rock layers 4 and 8 were deposited during the same geologic period because both layers (1) contain the same index fossil (3) contain index fossils of the same age (2) are composed of glacial sediments (4) are found in the same area Lee Trilobite fossils are found worldwide, with many thousands of known species. Because they appeared quickly in geological time, and moulted like other arthropods, trilobites serve as excellent index fossils, enabling geologists to date the age of the rocks in which they are Index fossil definition is - a fossil usually with a narrow time range and wide spatial distribution that is used in the identification of related geologic formations. Graptolithina is a subclass of the class Pterobranchia, the members of which are known as graptolites.These organisms are colonial animals known chiefly as fossils from the Middle Cambrian (Miaolingian, Wuliuan) through the Lower Carboniferous (Mississippian).

We read the information collectively, with particular emphasis on the definition of what constitutes an index fossil, and the criteria that make it one (1. existing for a short geologic period | 2. being spread over a large area).

Suture patterns and whorl characteristics are used to identify species. Ammonite females are believed to be larger than the males. Index fossils (also known as guide fossils or indicator fossils) are fossils used to define and identify geologic periods (or faunal stages). Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.

2020-09-16 · Evolutionary paleontologists use ‘index fossils’ to assign an age to a layer of sedimentary rock and its associated fossils. Evolutionary theory assumes that a particular creature evolved from its ancestors, lived successfully for a period, then became extinct as its descendants evolved better ways of surviving.

"LORD, how manifold are thy works! In wisdom hast thou made them all: the earth is full of thy riches" (Psalm 104:24). Evolutionists consider what they call "living fossils" to be rare, the famous Coelacanth fish being the best-known example. The fossils of this fish are found only in rocks older than 70 million years (assuming the standard geologic time scale to be real), but living

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 Good index fossils need to be both -- abundant and ; vulnerable; Abundant and globally widespread over a relatively short period of time. Vulnerable to environmental change and extinction. This combined "boom-and-bust character" is what makes for a good index fossil. Some index fossils are small or microscopic, part of the floating plankton in Index fossils. 1.
