B) Oceans were once much rough and sea life washed inland on giant waves is an appropriate answer.
Explanation:
- Most researchers have taken into consideration those uncommon organisms a few resemble segmented worms or fronds.
- And others appear to be not anything greater than bags of tissue to have lived withinside the sea due to the fact the styles of rocks that entombed them commonly collect as sediments in marine environments.
- Almost all fossils are preserved in sedimentary rock. Organisms that stay in topographically low places (consisting of lakes or ocean basins) have the pleasant hazard of being preserved.
- This is due to the fact they're already in places in which sediment is possible to bury them and safe haven them from scavengers and decay.
