Why are fossils from the Cambrian more abundant than fossils from the Precambrian?

Fossils from the Cambrian period are more abundant than fossils from the Precambrian period because the Cambrian saw a rapid diversification and proliferation of multi-celled organisms, resulting in a greater number of species and individuals that were able to be fossilized. The Precambrian period, on the other hand, was characterized by simpler, single-celled organisms that had not yet evolved into more complex life forms, making them less likely to be preserved as fossils. Additionally, the conditions for fossilization may have been less favorable during the Precambrian period, leading to fewer fossils being preserved and discovered.
