It is expected that seafloor samples taken farther from land usually contain a greater proportion of biogenous sediments because sediments are thinnest on the seabed closest to spreading centres (young seafloor) and thicker distant from the ridge (older seafloor with more time for accumulation). Additionally, sediments are substantially thicker close to continents.

More about seafloor sediments:

Terrigenous, pelagic, and hydrogenous sediment are the three different types of sea floor sediment. Terrigenous sediment is deposited on the continental shelf, continental rise, and abyssal plain and is derived from the land.

Clay particles and tiny marine animal skeletons that progressively sink to the ocean floor make up pelagic sediment. Minerals that precipitate from seawater on the ocean floor, such as manganese nodules, are abundant in hydrogenous sediments.

Would you expect to find dinosaur fossils in undisturbed rocks that are above the iridium
MrRissso [65]

Answer:

All dinosaur fossils found by archeologists have been found a few centimeters below the iridium layer. So, the possibility of finding dinosaur fossils above the iridium layer is very slim.

Explanation:

Over 65 million years ago, dinosaurs roamed the earth but were canceled out as a result of an extraterrestrial impact on the earth's crust. Research proved that an asteroid brought the end of dinosaurs as the element iridium was found in the earth (since iridium is abundant in asteroids and not the earth's crust).

Records of fossils found have been between 13 to 60 centimeters below the iridium or the K-T boundary as it is called.
