Moterites are a type of sedimentary rock primarily composed of mineral grains and organic materials, often formed from the accumulation of sediments in marine or freshwater environments. They can contain significant amounts of fossils, making them important for understanding past ecological conditions. The term may also refer to specific formations or layers within a geological context. However, "moterites" is not a widely recognized term in geology, so it may be a misspelling or a variation of another term.
