Ordovician age bedrock has yielded a variety of fossils, with one notable example being the trilobite. These ancient marine arthropods thrived during the Ordovician period and are commonly found in sedimentary rocks from that time. Other significant fossils include brachiopods and graptolites, which provide valuable insights into the marine ecosystems of the Ordovician.

What fossil of an organism that was common in one time period in multiple areas?

One well-known fossil of an organism that was common across multiple areas during a specific time period is the trilobite. These marine arthropods thrived during the Paleozoic Era, particularly in the Cambrian and Ordovician periods, and their fossils have been found on every continent. Their widespread distribution and diverse forms make them valuable index fossils for dating and correlating the age of the rocks in which they are found.


Where was the first human fossil found?

No one knows what the first fossil found was - humans have been collecting the oddly shaped stones for thousands of years around the world. It has only been in the last couple of centuries that fossils have been recognized as the remains of ancient and extinct animals.


Why were there no plants during the Cambrian time era?

There were simple plants in the Cambrian Period(542 - 488.3Ma). Fossil algae has been found in Cambrian Rocks. Evidence of primitive algae from the Precambrian Super-Eon has also been found but exact classification has not been established. It is true that embryophytes (Plants we most recognise) did not evolve until the Ordovician Period(488.3 - 443.7Ma).
