No. Many sediments interbreed at the bottom of rivers. You might have some sand that becomes sexually attracted to a piece of gravel. All the little pieces of sand fight each other to see who gets to mate. When one the sand particles attracts the rock's attention, she selects him, and they breed. The silica genes in the sand are mixed with the limestone genes in the gravel, and they have cute little baby geodes!

Tubiflex is a species of tubificid seqmented worm that inhabits the sediments of lakes and rivers on several continents.

The three types of ocean floor sediments are Terrigenous, Biogenous, and Hydrogenous sediments.
Plants grow on new sediments because these sediments often provide a nutrient-rich substrate that supports plant life. Additionally, the loose, well-aerated structure of newly deposited sediments facilitates root expansion and water drainage, promoting healthy growth. Over time, as organic matter accumulates and soil develops, these areas can become increasingly hospitable for a diverse range of plant species.
A simple bistro type set for two would be best for singl man.
Index fossils (also known as guide fossils, indicator fossils or zone fossils) are fossils used to define and identify geologic periods (or faunal stages). They work on the premise that, although different sediments may look different depending on the conditions under which they were laid down, they may include the remains of the same species of fossil. If the species concerned were short-lived (in geological terms, lasting a few hundred thousand years), then it is certain that the sediments in question were deposited within that narrow time period. The shorter the lifespan of a species, the more precisely different sediments can be correlated, and so rapidly evolving types of fossils are particularly valuable. The best index fossils are common, easy-to-identify at species level, and have a broad distribution-otherwise the likelihood of finding and recognizing one in the two sediments is minor. --- Wikipedia
