shell

I collect shells and interesting seaside items.

These strata are the product of those billions and billions of shells.

Replacement can be a marvelously precise process, so that details of shell ornamentation, tree rings in wood, and delicate structures in bone are accurately preserved.

In such cases, the original composition of the bone or shell remains, but the fossil is made harder and more durable.

The empty shell of a snail or clam may be left behind, and if it is sufficiently durable and resistant to dissolution, it may remain basically unchanged for a long period of time.

Raised beaches often consist of areas of sand, pebbles, or dunes, sometimes containing seashells or piles of debris comprising shells and bones of marine animals used by humans.

One was the grave of a human, buried with some tools, sea shells and other items, and nearby, a cat was buried in its own grave.

Trade in shell, obsidian, and other commodities seems to have been on the rise, and anthropologists suspect that the exchange of perishables (such as skins, foodstuffs) and salt was also on the increase.

They cracked the nuts and removed their shells.

If the Nightcap Oak remains…if their seeds remain locked inside their shell, they will not germinate.

Some of these coats are hard–like the shell of a nut–for extra protection.

The solid feel of the car's shell is impressive.

First through a low velocity core, and then through a high velocity shell, where their speed is increased before they are transmitted into the surrounding seawater.

They began to emerge like tortoises from their shells.

The beach was littered with broken crab shells.

We ate lobster served in its shell.

Interestingly, there are clams and snail shells; but, no fossils of fish.

The ratio of oxygen-16 to oxygen-18 found in the calcite of a foraminifer's shell depends on the temperature of the water in which the organism lived.

Many other processes may after the shell of a clam or snail and enhance its chances for preservation.

Indeed, unaltered shells of marine invertebrates are known from deposits over 100 million years old.

Isotopic analysis of shells allowed geologists to measure another glacial effect.

These shells differ in their proportion of ordinary oxygen (oxygen- and the heavy oxygen isotope (oxygen-.

Some of the shells exploded near a hospital.

Remove the baked pie shell from the baking tin.

Once the eggs have hatched the shells are left behind.

The races are in six-oared shells.

They shelled the prawns that morning.
