It is clear that internal engine corrosion is prevelant and it is bad. Doing the math with general round numbers, if an engine overhaul costs $30,000, at 2,000-hour TBO, the cost is $15 per hour. Shorten the life of that engine by 500 hours and you have just lost $7,500. The causes â the debate. Scientists have long known how the process of corrosion occurs.

Fosssils are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers (strata) is known as the fossil record. Types:-. 1  mold fossils (a fossilized impression made in the substrate-a negative image of the organism). 2  cast fossils (formed when a mold is filled in). 3  trace fossils = ichnofossils (fossilized nests, gastroliths, burrows, footprints, etc.). 4  true form fossils (fossils of the actual animal or animal part).
