Thank you for your question.
The highest nutritional source of calcium is found in: Sesame Seeds.
They contain 975mg per 100g serving. which is 98% of the Daily Value.
Make sure they are whole (Unhulled) and not Decorticated.
This is Because 93.8% of the Calcium is found in the hull of the Sesame seed.
For Comparison:
1 cup (244grams) of Whole Cows Milk contains 276mg of Calcium. (28% of the Daily Value)
1 cup (244grams) of Whole Sesame Seeds contains 1404mg of Calcium (140% of the Daily value)

-If i find a higher source of calcium, this answer will be updated-
The highest calcium enriched foods would come from the dairy food group. These foods include milk, cheese of all sorts, yogurts. They are the highest in calcium.
cheese and yogurt
Because calcium is a soft metallic element, and a hammer (presumably made of iron) is harder and more dense than the calcium.
Some calcium rich food that would be good to eat would include most foods under the dairy group, such as milk and yogurt. Some other calcium rich foods include broccoli, spinach, almonds, sardines, and oranges.
dense
From most dense at the core to least dense proceeding outward.
Diamond No its calcium.
broccoli
Dairy products derived from skim milk are going to have the highest calcium content.
non-fat milk
Calcium is needed to repair bone tissue making them strong and dense.
There are lots of sources of calcium in food. For example the most common sources of calcium in food include yogurt, cheese, milk, juices and soy. If you feel you are not getting enough you can buy calcium supplements.
Calcium metal is more dense than water. If you had a block of calcium and dropped it in a container of water, it would sink. Note! Calcium reacts with water! Calcium metal is stored in a container beneath kerosene or another liquid to isolate the metal from air. Calcium will chemically react with the moisture in air and will thus be decomposed.

Fortification The addition of calcium to orange juice products by food manufactures is most properly termed nutrient fortification.
Nutrient-dense food
by drinking less milk or a calcium defficency
It;s White, or silvery. And it's not very dense
Eating food with calcium can make you taller.
