The main difference was that in the Pre Cambrian there were no large animals. As a result, there were no coral reef to make limestones. The Pre Cambrian is a very long period of time though (4 billion years). There are some major differences between early and late pre Cambrian rock.

What phylum was dominant during the Cambrian Era about 540 million years ago?
During the Cambrian Era, the dominant phylum was Arthropoda, which includes ancestors of modern insects, crustaceans, and arachnids. This period saw a rapid diversification of life forms in what is known as the Cambrian Explosion, leading to the emergence of many major animal phyla. Other significant phyla during this time included Mollusca and Annelida. The Cambrian period marked a crucial evolutionary step, setting the foundation for complex life on Earth.
What are the eras of the CAMBRIAN?
The Cambrian Period is divided into three eras: the Early Cambrian, Middle Cambrian, and Late Cambrian. These eras refer to different stages or time intervals within the Cambrian Period, which lasted from about 541 to 485 million years ago. Each era is characterized by different geological and biological events, including the diversification of early animal life.
