According to young-Earth creation views, when were most fossils formed?

According to young-Earth creation perspectives, the belief is that most fossils were formed during Noah's Flood. This viewpoint holds that the catastrophic event described in the biblical account led to the rapid burial of organisms, which consequently resulted in fossilization. The flood is seen as a dramatic, worldwide event that would have generated the conditions necessary for the fossilization process, such as sedimentation and rapid covering by materials, thereby preserving remains in a much shorter timescale than what is typically proposed by conventional paleontology.

This belief contrasts sharply with the idea that fossils formed over millions of years, as is commonly accepted in mainstream geology and paleontology. The young-Earth creation view posits a much younger timeline for Earth's history and the processes involved in fossil formation, emphasizing a more immediate and direct connection between biological extinction and sedimentary processes associated with the flood rather than gradual, gradualistic changes over extensive geological time.
