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.

For an aerial shell, rule of thumb is about 50-80 feet per shell inch.
1300 cm = 42.7 feet.
There are 0.3048 metres in one foot. Therefore, 1300 feet is equal to 1300 x 0.3048 = 396.24 metres.
100/1300 * 100% = 7.692%
There are 12 inches in one foot. Therefore, 1300 inches is equal to 1300/12 = 108.3 recurring (that is, 108.3333...) feet.
