The presumed animal fossils first appeared during the Archaean Cambrian period. There is no clear indication why they appeared this late into history.
Magic
Large numbers of fossils begin to appear around 530 million years ago. It is called the Cambrian Explosion, because it occurred in the Cambrian period. The Cambrian period was the first part of the Paleozoic era.
Dinosaurs
That is correct. The fossil record shows that human fossils appear in Africa long before they appear anywhere else.

molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.
Animal life first appeared in the oceans around 600 million years ago during the Ediacaran period.

Archaeopteryx was the first animal discovered that had both defining bird and dinosaur traits.
The oldest animal fossils on Earth are significant because they provide important clues about the early evolution and diversity of life on our planet. By studying these fossils, scientists can better understand how animals first appeared and evolved over time, shedding light on the history of life on Earth.
Just keep trying, the first time you look for fossils, they are quite rare, but once you have found a fossil for the first time, they appear more commonly.
Cycads first appeared in the fossil record during the early Permian period, around 280 million years ago. They are often referred to as "living fossils" due to their ancient lineage and resemblance to plants from that era.
