Glutamic acid is a natural constituent of many fermented or aged foods, including soy sauce, fermented bean paste, and cheese, and is also a component of hydrolyzed protein such as yeast extract. The sodium salt of glutamic acid, monosodium glutamate (MSG), is a widely used additive in the food industry.
Paleontologistâs estimate that only a small percentage of the dinosaurs that ever lived have been or will be found as fossils, because their bodies simply decayed. The word fossil comes from the Latin word fossils, which means, âdug upâ. Most fossils are excavated from sedimentary rock layers. Sedimentary rock is rock that has formed from materials like sand, mud, and small pieces of rock. Over long periods of time, these small pieces of debris are squeezed and are buried under more and more layers of sediment that piles up on top of it.
Report Abuse. Fossils are generally found in sedimentary rocks formed by soft silts and muds. The soft sediment preserves the fine details in the bones, teeth, and leaves of plants. Sometimes sediments fill an opening in a bone or shell and leave behind a cast of the inside of the living thing.ossils cannot form in metamorphic or igneous rocks since metamorphic rocks are formed under extreme pressure and heat and igneous rocks are formed from magma both of which will destroy the fossil.
