Fossils can be discovered through various methods, but two common ways are:
-
Excavation: Paleontologists and fossil hunters often conduct systematic digs in areas where fossilized remains are likely to be found, such as sedimentary rock formations, riverbeds, or sites known for past geological activity. These excavations can involve digging with tools to carefully uncover and collect fossils.
-
Erosion and Natural Exposure: Fossils can also be revealed through natural processes like erosion, landslides, or riverbank cutting, which remove sediment layers and expose fossilized remains at the surface. These fossils can then be found by casual observers or researchers exploring exposed rock formations.
