Fossil limestone rock

Formed over millions of years, limestone is a sedimentary rock

INTRODUCTION. Rocks, minerals, and fossils found on the surface of Dallas and Tarrant Counties were deposited in the Mesozoic Era and Cenozoic Era. (See Geologic Time Chart) The resulting formations are either of Cretaceous Age, 145 to 66 million years ago (ma) or Quaternary Period, 2.58 ma to present. In Dallas County, the Cretaceous Period ... Real fossils will only turn up in particular rock formations in certain areas around the world. Using data from the Paleontology Database, this (very cool) interactive map can show you everywhere on Earth where dinosaur fossils have been found. (Of course, before breaking ground in a dino-heavy region, make sure you're obeying the law.Sedimentary rock - Limestone Formation, Calcium Carbonate, Fossils: Limestones originate mainly through the lithification of loose carbonate sediments. Modern carbonate sediments are generated in a variety of environments: continental, marine, and transitional, but most are marine.

Professor Cam Nelson. Scientifically, you know, limestone is important because it contains many fossils, and those fossils can be used to date the rock so that the geological period of time in which the limestone’s formed can be determined. The same fossils can tell us a lot about the environment in which the limestone formed.
