Question

Quizplus · Accepted Answer

Siltstone or mudstone containing marine fossils are typically formed in shallow-marine environments, where there is abundant biological activity and sediment deposition. Deep-marine environments have very slow sedimentation rates and do not typically contain abundant fossils. Marine-delta and coastal-beach environments may contain marine fossils, but are unlikely to form siltstone or mudstone due to the dominance of sand-sized particles in these environments.
