Sediments can be deposited by wind or water but water moves most.
Loess is wind deposited particles. Alluvium is water deposited soil.
The particles are one part but the place they settle impacts how they become rock because the geologic process will be different at the bottom of a deep marine sea than it is in a shallow off shore shelf.
Only the very smallest particles will be moved to mid-ocean but there will be many plankton and other organic deposits.
Coastal particles will vary in sizes . Water temperature will have more impact on the organic contributions here. Shallow tropical waters have coral and can form limestone.
There are multiple characteristic that all dinosaurs shared. Some of the synapomorphies include:
- Vertebrates; skeletons with back bones that surrounds a nerve cord.
- Amniotes; specially adapted for life on dry land.
- Diapsids; two holes located above and behind the eye sockets on each side of the skull.
- Archosaurs; antrobital ferestra, a hole between the nasal hole and the eye socket hole.
But still all of this doesn't separate them from all others, what is unique to them is that all of the 'true dinosaurs' were land dwellers.
