the oceans receded
The Chumash clan used shell bead money, part of the Olivella shell, a shell found mostly in the islands of California.
Ammonite can refer to both an ancient shell and an ancient people. The term "ammonite" originally referred to the extinct marine mollusk with a distinctive coiled shell that lived during the Jurassic and Cretaceous periods. Later, it was also used to describe the people who inhabited the ancient region of Ammon, located in present-day Jordan.
Probably the World Turtle, found in multiple cultures. It holds the world on its back, or even, in some myths, inside its shell.
Yes, but not a hard shell like a peanut or pistachio. Cashew nuts are an accessory fruit of the cashew tree (characterized as a drupe). They grow on the underside of a very tender fruit called a cashew apple. Although the cashew nuts don't have a hard shell, they are covered by a thin double 'shell' which contains a skin irritant called anacardic acid and urushiol. Urushiol is the same chemical the is found in poison oak, ivy, sumac, and Japanese black laqer tree.
The electron outside the shell donate its electron to the one inside the shell
Absolutely yes, fossils of some shell creatures, like snails can be found in dry valley floors.
Yes, scallops can form fossils. Fossils are formed when the hard parts of an organism, such as the shell of a scallop, are preserved in sedimentary rocks over long periods of time. Scallops have been found in fossil form dating back millions of years, providing evidence of their ancient existence.
a trilobite is an hard shell and it was found 230 millions years ago...
You can find the Helix, Shell and Old Amber fossils. However you can only gain two in the game. Helix or Shell as the trainer you fight in Mt Moon that found them will only allow you to take one. The Old Amber can be found at the back entrance to Pewter Museum (you will need Cut)
Yes, shell-shaped minerals can be found in rock cavities known as geodes. These geodes can form in sedimentary or volcanic rocks and can contain minerals such as quartz, calcite, or amethyst that have crystallized within the cavity. While not actual fossils, geodes are a type of mineral formation often found in rock cavities.
Marine fossils form when creatures die and sink to the bottom where there is little oxygen, and are covered with sediment. If sediment continues to accumulate, after many years its weight will crush the deposit, and in combination with well known chemical processes, can cement it into sandstone. Later, if the sea floor it lifted by any of a number of (again, well understood) geological processes, what was once the sea floor can become part of a mountain. Such a mountain can form in a few million years, where fossils have been forming for 3 BILLION years.
a shell
The sarcodine with a shell made of calcium carbonate is Foraminifera. These single-celled organisms secrete intricate shells that are commonly found as fossils in marine sediment.
fossils are small living organisms that existed millions of years ago. They mostly have a shell which is the fossil that you can sea. Sedimentary rock is formed when lots of small particles and pieces of rock and often dead organisms, (the fossils) drift down to the sea bed and over millions of years get compressed together to form the rock. The fossil that you see was once a living shelled organism which dies and was preserved as the sedimentary rock formed
The difference between The differeence between the Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of thee evolved predators. The difference between Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of the evolved predators.rian fossils Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of the evolved predators.
The 5 types of fossils are ...Imprint Fossils- an organism leaving an imprint on sediment that later hardens into rock.Mineralization Fossils- when minerals replace wood or bone to create a piece of petrified wood or a mineralization bone fossilsFrozen Fossils- when something like an animal gets taped in ice and remains their frozenCast Fossils- when it fills up a hollow moldfossils in amber- when an insect gets stuck in amber
inorganic minerals replace the bones and shells in fossils. However, some recent demineralization experiments have indicated that some original connective tissue may remain, even in very old fossils.
