Formation of dinosaur fossils:
The petrification process begins when a dinosaur dies and is quickly covered by sediment or underwater mud. These sediments contain tiny particles that form a loose covering over the surface of the carcass. This "blanket" protects the carcass from scavengers and also insulates it from oxygen and inhibits the decomposition of microorganisms.
The hard parts of dinosaurs, such as bones and teeth, are made of minerals. Minerals tend to break down and recrystallize underground, becoming harder, a process known as "Petrochemical process". As the sediment above thickens, the remains become buried deeper and deeper, eventually becoming fossilized.
The discovery of dinosaur fossils is the most crucial step in the study of dinosaurs. Fossils are mostly preserved in sedimentary rocks, and there is a certain pattern of fossil outcrops.
Today, paleontologists have been able to see inside fossils without destroying them through advanced instruments, and they can also see subtle internal structures that were not possible to examine in the past. This can provide insight into how dinosaurs lived, ate, grew, and moved, as well as learning about the evolutionary lineage of dinosaurs.
